Who are you?
In the physical world, you’re identified by your name, passport, driver’s license, bank account logins, and other credentials. But how do you prove who you are online—when ordering something, transferring money, or logging into your company network?
That’s where your digital identity comes in.
A digital identity is a set of data that uniquely identifies a person, organization, application, or device on the internet. It is used to verify the identity and authorize access to specific resources or data online. Your name, email address, date of birth, home address, IP address, and social media profiles are the main contributors to your digital identity.
Your digital ID is your online persona. It is how you navigate the web, interact, and authenticate yourself for services like social media, banking or work meetings. It also extends beyond individuals to organizations, devices, and software, creating a trusted network. Technologies like identity and access management software and decentralized identity solutions help create and manage secure digital IDs today.
A good digital ID is verified, unique, privacy-focused, and gives users control over their data. Businesses rely on digital IDs to enhance security, compliance, and customer experience, ensuring they know exactly who or what is accessing their network.
Read on to learn why digital identity is important, its key concepts, types, challenges, use cases and how to secure your digital identity with identity and access management.
A wide range of entities possess a digital identity, including:
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:
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.
Digital identities consist of various components like include identifiers, attributes, and other related information. These elements work together to represent an individual, device, or organization in the online world. Let's see them in detail.
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:
These identifiers link users to digital platforms, ensuring the correct person is granted access to the appropriate resources. They also help in tracking activity and personalizing user interactions.
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. Examples of digital identity attributes include>
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).
Understanding what makes up a digital identity is only part of the picture. Authentication and authorization are two critical processes in online identity and access management makes secure interactions with different systems, resources, and services possible. Without proper authentication and authorization, digital identities remain vulnerable to misuse. Let's learn more about these two concepts.
Authentication is the process of verifying the identity of a user, system, or entity trying to access a particular resource or system. Often, digital credentials are used for authentication. It vouches for the identity of the digital entity through some form of trust and authentication.
Common authentication factors include:
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.
As mentioned earlier, digital identity extends beyond humans to devices and software applications. Here are the three types of 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.
An individual's digital identity can be interpreted in four ways:
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:
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.
There are various digital IDs we use every day, each with its own unique purpose and characteristics. Here are some examples:
We all use digital identities in some form, whether we're logging into a website, shopping online, or even accessing healthcare services. Digital identities help make these interactions more secure and efficient. Here are a few common ways they're used in everyday life across different industries:
Security is the first and foremost reason why digital identity management 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.
Despite the immense benefits and opportunities digital IDs offer, it comes with the following risks and challenges.
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.
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.
of hacking-related breaches occur using brute force tactics or lost or stolen credentials.

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

The world is gradually moving toward a time when individuals’ online identities match their real-life identities and provide a global and accurate view of who they are, what they do, and how they see themselves.
As digital identity solutions continue to develop and mature, we can expect to see even more innovative and secure ways to manage our digital identities. This will enable us to reap the full benefits of digital identity, such as the ability to access services more easily and securely and to share our data with others in a controlled and privacy-preserving way.
