# Single sign-on (SSO)

Overleaf Commons supports a standard SAML single sign-on (SSO) configuration.

With Overleaf Commons SSO, new users can create their Overleaf accounts and enrol in the subscription (if eligible) by logging in with SSO. Users who already have an Overleaf account can link their SSO identity to their existing Overleaf account and join the subscription if eligible. We recommend that all authenticated users at an institution be authorized to log in to Overleaf, and if there are restrictions on which users should be added to the subscription, users' entitlements can be verified using data sent at log in time.

Users can log in to their Overleaf accounts with SSO either through your portal page or our[ main SSO login page](https://www.overleaf.com/sso-login).
