Single Sign-On (SSO) Explained

Single Sign-On, commonly known as SSO, is an authentication process that enables users to access multiple applications using a single set of login credentials.

Benefits of SSO

• Enhances user experience by reducing the number of times users have to log in.
• Reduces password fatigue from different username and password combinations.
• Decreases the risk of forgotten passwords and reduces IT costs related to password recovery.
• Improves identity protection by limiting the potential exposure of authentication credentials to malicious actors.

How SSO Works

When a user first logs into an SSO-enabled application, the SSO server authenticates their credentials (usually a username and password). Upon successful authentication, the SSO server issues a token. When the user then attempts to access a second application, this token is used to verify their identity, so they don't have to log in again. This token-based system allows seamless transitions between connected applications during the user's session.

Conclusion

While SSO offers many advantages, organizations need to implement it securely. It's essential to keep in mind that while it simplifies the user's experience, it also presents a single point of access to multiple systems. Thus, securing this access point is crucial.
