# Authentication

<Warning>If you're deploying Sourcebot behind a domain, you must set the [AUTH\_URL](/docs/configuration/environment-variables) environment variable.</Warning>

Sourcebot's built-in authentication system gates your deployment, and allows administrators to manage users and their permissions.

# Session lifetime

By default, session cookies remain valid for 30 days from the time they are issued, after which the user is signed out and must authenticate again.

You can change this by setting the [`AUTH_SESSION_MAX_AGE_SECONDS`](/docs/configuration/environment-variables) environment variable to the desired lifetime in seconds.

A session is guaranteed to remain valid for at least its configured lifetime. The JWT verifier applies a small clock-skew tolerance when checking expiry, so a session may continue to be accepted for a brief additional window past that point before it is rejected.

# Troubleshooting

* If you experience issues logging in, logging out, or accessing an organization you should have access to, try clearing your cookies & performing a full page refresh (`Cmd/Ctrl + Shift + R` on most browsers).
