P4 CLI Reference | 2025.1

# P4LOGINSSO

Client-side single sign-on (SSO) script.

Triggers of type `auth-check-sso` fire when standard users run the `p4 login` command.

Two scripts are run: a client-side script is run on the user’s workstation, and its output is passed (in plaintext) to the P4 Server, where the server-side script runs.

## Notes

If this value is not set on a server that is configured to use SSO-based login, the user will either have to use password authentication or the user will be denied the ability to log in. See Single signon and auth-check-sso triggers in the P4 Server Administration Documentation.
