Single Sign-On

An authentication mechanism that allows users to log in once with a single set of credentials and gain access to multiple applications or systems without needing to log in separately to each one.

Single sign-on dramatically improves user experience by eliminating password fatigue. For business software used alongside other tools, SSO integration is often a requirement for enterprise customers and a significant factor in product adoption.

A founder's project management tool integrates SSO through Google Workspace. Her B2B customers can log in with their existing company Google accounts, eliminating the need to create and remember separate credentials and making adoption frictionless for entire teams.
