8 Best Free SSO Software Tools in 2019

September 11, 2019

We sure do spend a lot of time signing on.

Not only is it time-consuming, it’s often a humbling experience. (For example, how often have you asked yourself something like, “Was the ‘B’ in this password capital or lowercase?” quickly followed by “Am I losing my mind?”)

Single sign-on software offers a solution for business users struggling to keep track of their umpteen different logins—191 on average, according to a 2017 report by LastPass. With one rock-solid set of credentials, or even a face scan, users of this software can access all of their important apps and databases.

How single sign-on helps your business 

Except for a few masochists out there, the daily routine of logging into a million different accounts is a chore at best. Single sign-on solutions is one way around it.

Whether you’re seeking added convenience for your clients or for your office staff, these free single sign-on tools can help eliminate the time and stress that goes into entering passwords. And for IT teams, these products can help add a layer of control and security to your network’s daily technology usage.

To sweeten the deal, there are several worthwhile options on the market that are free to download and use.

SSO software is not to be confused with password managers, which helps users remember their respective logins for different accounts and autofill them when desired. If password managers were like a map to help you find your way, SSO is like a key that opens all the doors at once. “One and done,” as they say.

The benefits of single sign-on technology are especially realized with interlinked, on-premises systems or families of software. Some platforms are designed to be used with certain brands or software types, and a number of platforms in this category are multipurpose security tools that fall into other categories as well.

Whatever the case may be, a successful deployment of SSO in your business—with a little help from your IT team—can be a shot in the arm to your team’s productivity. In some cases, developers will use these tools to add convenience and security to their customer-facing apps. In other cases, SSO can be a saving grace in one’s personal life, consolidating the time spent pounding the keyboard and preventing a headache or two in the process.

To help get you started, we’ve assembled a handful of SSO platforms that don’t require a financial commitment. The products featured here have more than 120 verified user reviews* on G2 as of July 9, 2019, and represent only a portion of the 90 products in the Single Sign-On category.
