2 Week Default
By default, the web session length for Google services is 14 days. These settings apply to all desktop web sessions, as well as some mobile browser sessions.
Native mobile apps, like Gmail for Android and iOS, aren’t impacted by these settings.
Admins can modify durations
Workspace admins have the ability to specify the duration of web sessions for Google services (e.g. four hours, seven days, or infinite). Unless a user logs out beforehand, they’ll be automatically signed out at the end of that duration and prompted to re-enter their login credentials.
