What Is Digital Identity? How to Create a Secure Digital ID

March 7, 2024

digital identity

Who are you? 

Often, you identify with your name, where you were born, what you've studied, who you work for, and where you live. You’ve got a passport, driver’s license, employee badges, bank account logins, and personal identification numbers. You have a lot of identifiers in the physical world.

But how do you prove who you are in the online world - when you want to order something online, do an online bank transfer, or log in to your company network as you work from home? 

That’s where your digital identity comes in. 

Digital ID is how you navigate the web, interact with others, and authenticate yourself for a plethora of services - from online banking to team meetings at work. It's your online persona, your virtual thumbprint, and, in essence, it's 'you' in the digital domain.

This digital identity extends beyond individuals to include organizations, devices, software programs, and applications. Just as the computers authenticate an individual's presence online, they also validate the identity and permissions of connected devices and applications in the network, thereby creating a web of trust.

A good digital ID is verified, unique, established with an individual’s consent, protects user privacy, and ensures control over personal data.

Businesses and other organizations use digital IDs to strengthen security and compliance and improve customer experiences. Their IT and security teams get to know precisely who and what systems are accessing their network and what resources are being utilized, all through the digital IDs assigned to individuals, systems, and entities on their network. 

Technologies like identity and access management software and decentralized identity solutions help create and manage secure digital IDs today. 

Why is digital identity important?

Security is the first and foremost reason why digital identity is important. It provides a means to verify the identity of individuals, devices, and entities online. This authentication is essential for secure online interactions and transactions and to prevent unauthorized access, identity theft, and fraud. By establishing a robust digital identity framework, individuals and organizations protect themselves against rising cyber threats.

Companies, in particular, use digital IDs to secure data and restrict unauthorized users from accessing business-sensitive information with identity and access management. It reduces the risk of data breaches and the resulting operational, financial, and reputational damages from such attacks. 

Privacy control is the second major reason why digital IDs are important. With the ability to manage and authenticate their digital identities, people can choose what data to disclose and to whom. This empowers users to safeguard their data privacy in an era where personal data is highly valuable and susceptible to misuse.

For example, imagine you're using a social media platform, and you want to share some personal information, like your birthday, with your friends, but you don't want this data to be visible to everyone on the platform. With your social media ID and privacy control settings, you can select the specific information you want to share, in this case, your birthday. If you change your mind in the future or if you no longer want to share your birthday, you can easily adjust your privacy settings to restrict or expand access.

Digital IDs also provide convenience with instant virtual authentication. It builds trust between users, organizations, and services. It ensures that users are engaging with legitimate entities, promoting confidence in online interactions that happen, be it for essential amenities like banking, healthcare, government services, and e-commerce or for other purposes like social media networking. 

Apart from these reasons, digital IDs reduce paperwork, time, and costs associated with manual procedures for businesses by automating identity verification and authentication processes. This improves operational efficiency and business agility. Digital identity solutions also assist organizations in meeting the regulatory requirements for data protection and privacy, reducing legal risks and potential liabilities.

Who processed digital IDs?

A wide range of entities possess digital IDs, including: 

  • Individuals: Anyone using a computer or the internet
  • Devices: Computers and connected Internet of Things (IoT) devices possess their own form of digital identity, identified using IP addresses, MAC addresses, etc. 
  • Organizations: Private companies, government bodies, and civil society organizations maintain a range of digital identities for themselves and their employees, including (third-party) co-workers) for the people they serve (customers, citizens). 
  • Software programs, applications, network systems, databases, microservices, and application programming interfaces (APIs) in an organization’s network have digital identities to authenticate themselves to ensure trust in data exchanges

Digital identity vs. identity vs. users vs. accounts

It’s very easy to get confused with the terms "digital identity," "identity," "users," and "accounts.” 

But they have distinct meanings. Here's a brief breakdown of each term to clarify the differences: 

  • Identity refers to the unique attributes and information that define an individual, entity, or system. Identity is the broadest concept, encompassing all aspects of who someone or something is. Often, it includes your name, date of birth, physical address, email address, and more.
  • Digital Identity is a subset of identity that specifically pertains to an individual or entity's online presence and interactions. It includes online profiles, login credentials, digital behaviors, characteristics, and other attributes. Even a pseudonymous profile linked to a device ID can be a digital identity. 
  • Users are individuals or entities in a digital platform, computer system, or network using digital IDs. 
  • Accounts are specific, often password-protected, access points within digital systems or platforms to manage and control access. It stores information about users, such as their name, email address, password, privileges, and permissions. While accounts are important to verify a user’s digital identity in a platform, it’s not essential in all cases.   

For example, a person may have an account on Facebook with a username and password to be a user of the social networking site. Their username, profile picture, friends list, posts, likes, comments, and other activities on Facebook become a part of their digital identity. This Facebook profile is once again part of their identity.  

Key concepts of digital identity

Here are five basic concepts that shape digital identity. Understanding this is necessary to comprehend how digital identities are created, managed, and secured. 

Digital identifiers 

Digital identifiers are unique pieces of information that represent the digital identity of individuals, devices, or organizations. They are highly context-specific, meaning digital identifiers can be completely different for various systems and applications. 

For instance, the digital identifiers of an individual on an e-commerce platform might be a username or email address, while in the context of an organization they are working in, it could be an employee ID or a specific role-based account. 

Digital identifiers are used to:

  • Authenticate users to online services 
  • Authorize access to resources 
  • Track user activity 
  • Target users with advertising 
  • Provide personalized experiences

Common digital identifies include:

  • Username
  • Email address
  • Biometric identifiers like a fingerprint or facial scan 
  • Device ID  
  • Uniform resource locator (URL)
  • Internet protocol (IP) address
  • MAC address
  • Government-issued identifiers like social security number in the U.S. or Aadhar number in India, driver’s license  

Digital identity attributes

Digital identity attributes are pieces of information that describe a digital identity. Attributes can be static, like name, date of birth, work experience, and job title, or dynamic, like browsing history, location data, purchasing behavior, and financial data. 

Note the distinction between digital identifiers and digital identity attributes is not always clear-cut. For example, a username can be used to both identify a user and to describe them (e.g., a username that includes the user's name or job title).


Authentication is the process of verifying the identity of a user, system, or entity trying to access a particular resource or system. Credentials are used for authentication. 

Common authentication factors include: 

  • Something you know ( a password or PIN or security question like “What’s your nickname?”). 
  • Something you have (a smart card or mobile device, a verification code sent to your email or phone number). 
  • Something you are (biometric data like fingerprints, voice recognition, or facial recognition).


Credentials are pieces of information that are used to verify digital identity. It vouches for the identity of the digital entity through some form of trust and authentication. The verification can be through a simple password or PIN or more complex, like a digital certificate or two-factor authentication token.


Authorization determines what actions or operations an authenticated user or system is allowed to perform within a given system or resource. Once a user or entity is authenticated, authorization specifies the level of access and permissions granted, defining what the user can or cannot do.

Typically, a person’s identity determines the permissions they have. For instance, your CEO might have access to all data in your organization, while you might have access to only the data you need for your work.

Types of digital identity

As mentioned earlier, digital identity extends beyond humans to devices and software applications. Here are the three types of digital identity.

1. Human digital identity

Human digital identity is associated with individual people and represents their online presence and interactions. Based on the purpose and platform an individual uses it for, it can be social media identity, email-based identity, government-issued identity, corporate identity, or customer identity. It’s important to remember that the digital identity for personal use is often different from the ID used for business purposes, and enterprises keep it that way to reduce the risks of data breaches

4 dimensions of human digital identity

An individual's digital identity can be interpreted in four ways: 

  •  Digital identity as a credential includes key information that people traditionally use to identify themselves. This information can be found on government-issued documents like driver’s licenses, passports, birth certificates, or health cards.
  • Digital identity as character can be summed up as an individual’s self-portrayal online. This identity is controlled solely by the individual who shapes online profiles through their commentary, activities, and self-descriptions.
  • Digital identity as user is the collection of information related to an individual’s digital behavior. It is typically collected by counterparties with which an individual interacts along with third parties to whom an individual has given permission. The picture of an identity is constructed through an accumulation of actions that reveal habits, interests, preferences, and priorities.
  • Digital identity as reputation is derived from information that is publicly available and created by reputable third parties. An identity is revealed through an individual’s history. These records often follow an individual and can impact things like employment opportunities, renting opportunities, and more.

2. Machine digital identities

These identities represent non-human entities, like devices, including computers, smartphones, IoT gadgets, applications, and services. The media access control (MAC) address of your computer is an example of device ID. 

Today, machine identity management, the process of assigning, monitoring, removing, and organizing digital IDs of devices and applications in an organization’s network, has become a top priority for the IT and security teams for three reasons:  

  • The explosion of a number of devices and applications that are connected to enterprise networks.
  • The adoption of hybrid and multi-cloud environments.
  • The shift to work from anywhere on any device norm.

3. Cloud digital identity

Cloud digital identity is used to securely access cloud-based services and applications. Cloud identities are central to cloud security, given the rising cloud adoption. Today, many IAM solution providers offer cloud-based services for fine-grained access control and visibility for centrally managing enterprise cloud resources. 

Types of digital IDs used daily with examples

There are various digital IDs we use every day, each with its own unique purpose and characteristics. Here are some examples: 

  • Government-issued digital IDs to avail government services online. Estonia has state-issued digital ID to pay bills, vote online, sign contracts, access their health information, and much more.
  • Employee digital ID used to access the company network and resources. For instance, I use my work email address to log into my company laptop.  
  • Digital banking ID to access online banking services, check bank account details, and make digital payments
  • Social media digital IDs like Facebook, X (formerly known as Twitter), Instagram, and LinkedIn accounts.

Challenges and risks of digital identity 

Despite the immense benefits and opportunities digital IDs offer, it comes with the following risks and challenges. 

Security and privacy risks

Digital IDs have inherent privacy and security risks. Your personal identifiable information (PII) that’s online is susceptible to potential data breaches and other cyber attacks.  

Common digital identity attack vectors

Digital identity attack vectors include: 

For individuals, losing personal data can lead to identity theft, financial and reputational loss, and emotional distress. 

For enterprises, even a single account breach can not only result in losing sensitive data but also compromise the whole network. Stolen or lost credentials can be used for account takeover, privilege escalations, ransomware, and other cyberattacks on the enterprise infrastructure. This is why user identities are hot commodities in the dark web, where “privileged accounts” and credentials of enterprise accounts are traded every day.

Complexity and lack of standardization 

Digital identity is a complex ecosystem involving a variety of stakeholders and technologies. A person has 90 digital identities. These identities are managed by the government, public and private companies, and other service providers. Different approaches to digital identity by different entities make it difficult to implement and manage digital identity solutions efficiently.

Further, many governments are still exploring and implementing new regulations to protect the personal data privacy and digital identity of their citizens. However, the standard varies across countries. As a result, companies have to meet different regulations like the EU’s General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and many more. They are also expected to follow other guidelines, such as the Cybersecurity Framework.

The lack of common standards creates issues for the effectiveness and robustness of an identity system, including problems with interoperability and interconnectivity.

Despite the challenges, the benefits individuals and enterprises get from digital identity are substantial. To maximize these benefits while mitigating risks, it's essential to use a robust digital identity management system with the necessary security features.

How to protect your digital identity: best practices for individuals and enterprises

Whether you're a consumer or part of a company’s security team, the following tips will help you keep your digital identity safe.

For individuals

As an individual, all it takes is a few extra precautionary steps to safeguard your online presence from breaches and frauds, and they ain’t tough. So, here are a few simple things for you to get started.  

  • Use strong, unique passwords. Avoid using easily guessed words or phrases such as your name, birthday, or address. Need be, use a password manager.
  • Enable MFA for your accounts. MFA adds an extra layer of security as you need a code from your phone or another device in addition to your password when logging in to an account.
  • Be mindful of the information you share online. Only share personal information with websites you trust. Avoid sharing your SSN, credit card number, and other sensitive data on social media or in public forums.
  • Review your privacy settings on social media and online accounts. See who can view your profile information, posts, and friend list, and make sure you’re not sharing your details with people you don’t intend to. 
  • Be suspicious of any emails or websites that ask for your personal information, especially if they come from an unknown sender or look suspicious to dodge phishing attempts.
  • Install and regularly update antivirus software. If possible, encrypt sensitive data on your devices and regularly back them up. 

For enterprises

Companies have a much larger number of digital identities to manage, including employee accounts, customer accounts, and machine identities, distributed across a variety of systems and applications, on-premises and in the cloud. This makes it challenging to track and manage all of them effectively. Further, organizations are subject to a variety of industry-specific government regulations. 

Here are some specific steps that enterprise IT teams can take:

  • Enforce strong password policies and implement MFA for employees. IAM solutions are the best bets for managing user accounts and access privileges with ease.
  • Establish strict remote work protocols so that employees access enterprise systems and data in a secure manner with mobile data security tools
  • Monitor your systems for security threats using networking monitoring tools and intrusion detection systems. Also, protect endpoints with endpoint protection suites
  • Educate your employees on cybersecurity threats. Let them know how to create strong passwords, spot phishing scams, and keep their devices shielded.

The future of digital identity: emerging trends

Technological advancements, challenges to existing centralized digital identity management systems, evolving needs, and changing user expectations are rapidly transforming the digital identity landscape. Here are four key emerging trends that are likely to shape the future of digital identity. 

Government IDs on the rise

Today, governments around the world are heavily investing in digital identity services and frameworks not only as primary means of establishing and authenticating an individual but also for accurate and efficient delivery of government services. Countries like Austria, Estonia, India, Korea, Portugal, Spain, and Uruguay already have their digital IDs linked to their population registry. Australia, the European Union, and many other countries are in the process of implementing their digital identity system. 

By 2024, it’s expected that 5 billion digital IDs will be issued globally by different governments.

Did you know? India has the largest national digital ID system in the world, with more than 1.2 billion enrollments for its Aadhar digital ID. 

Government digital IDs provide immense benefits for businesses, too. For example, government-issued digital IDs make it easy to verify a person. Banks, financial institutions, and telecommunication companies speed up the know-your-customer (KYC) process using government-issued digital IDs. Organizations use it to verify customers and employees. 

New biometric authentication methods

Biometric authentication methods, such as fingerprint, voice, and facial recognition, are becoming increasingly sophisticated and secure. It’s more attractive than the traditional way of keying alphanumeric passwords. They are effective against brute force attacks and phishing and provide user convenience as they don’t have to remember many passwords.

DLT-powered decentralized digital identity

The use of distributed ledger technology (DLT) and blockchain to create decentralized digital identity systems has been on the rise to address the problems faced by traditional, centralized, and federated identity systems.  

A decentralized identity system gives individuals more control over their own data and makes it easier to share their identity with others without having to go through a central authority. Companies, especially banking and financial services, are eager to adopt the technology to prevent fraud and improve customer authentication and regulatory compliance. It’s estimated that the global decentralized identity market will surpass $100 billion by 2030. 

A parallel trend on the rise is the move towards sovereign self-identity (SSI) systems. SSI allows individuals to create their own digital identities and share them with others without having to go through a central authority, supported by decentralized identity solutions.
