Access and security
Single sign-on
Microsoft Entra ID and Google, configured per deployment.
Entra ID and Google appear as sign-in options only when they are configured. They are not a paid tier feature — see Plans.
Signing in through a provider grants no membership
It proves control of an email address and nothing else. A new user arriving through single sign-on lands on onboarding exactly like anybody else, and joins an organisation only by invitation, by directory provisioning, or by creating one. Otherwise anybody inside a large directory could sign in and land inside somebody's HR data.
To provision and deprovision accounts automatically rather than on first sign-in, see Directory provisioning.
