Single Sign-On (SSO)

Single Sign-On (SSO) is an authentication method that enables users to securely authenticate with multiple applications and websites by using just one set of credentials. SSO works based on relationships (two-factor authentication) set up between an application and an authenticator, like LastPass or Google Authenticator. This trust relationship is often based upon a certificate that is exchanged between the authenticator and the service provider. This certificate can be used to sign identity information that is being sent from the authenticator to the service provider so that the service provider knows it is coming from a trusted source. In SSO, this identity data takes the form of tokens which contain identifying bits of information about the user like a user’s email address or a username.

What does this mean for an SMB?

Single Sign-On is a tool SMBs should consider adopting to assist in authenticating and managing users within your organization. Check out our article on Two-Factor Authentication to see what CyberHoot recommends in regards to strongly authenticating users. Any SSO solution you adopt must also support multi-factor authentication to properly secure users and their accounts.
Simplified User Access and Account Management
SSO is a great solution not only to simplify authentication across any organization, but also to keep your enrolled user lists and master database of active and inactive users current.  Managing a large number of online Software-as-a-Service solutions can be a daunting task.  However, SSO can greatly simplify the work of managing those solutions while simultaneously simplifying the number of passwords your users must remember to access the solutions.  It’s truly a Win-Win and something to be strongly encouraged in any company.
