Manage session duration

For added security, you can set up session duration to limit how long your members are signed in to Slack. 

How it works

• When you set up session duration, you can choose to have members sign back in whenever they close Slack or after a certain time period.
• To minimise disruption, you can warn your members before their sessions expire and give them the option to re-authenticate at that time. Members will be warned two hours before the session expires, with a final reminder 15 minutes before they’re signed out.
• Changes to session duration take effect on the day that you make them and will end member sessions randomly over the timeframe that you’ve selected. For example, if you set a session duration for seven days, session expirations will begin that day and continue gradually over the next seven days until all members have been signed out.
