# Log out

Bearer tokens are valid for a limited period of time. User bearer tokens will expire after 24 hours of inactivity, and application bearer tokens will expire after 10 minutes of inactivity. An application may terminate its session to immediately invalidate its bearer token.

> [!TIP]
> TIP
> 
> It is a good idea to do this before an application exits to limit the possibility of a stolen bearer token being used to access the Fortanix DSM server.
