Set up a passcode, fingerprint or facial scan to sign in to Slack

If an org owner requires a mobile passcode for their Enterprise Grid organisation, members and guests with unmanaged mobile devices must use a passcode or biometric authentication, such as a fingerprint or facial scan, to sign in to the Slack app on iOS or Android.

What to expect

  • If an org owner requires a mobile passcode, you’ll be prompted to enter a six-digit passcode the next time you open the Slack mobile app. You’ll also have the option to set up a fingerprint or facial scan if you have a compatible device. 
  • If your device ever fails to recognise your fingerprint or facial scan, you'll be prompted to enter your six-digit passcode.
  • Org owners can choose for you to authenticate every time you reopen the mobile app or when you’ve been away for more than 5 minutes, 15 minutes, 30 minutes, or 1 hour.
  • Org owners can choose how much information appears in notifications on your mobile device to keep potentially sensitive information secure.

Tip: If you forget your passcode, you can sign out of the Slack mobile app, re-authenticate with single sign-on, then reset your passcode and your fingerprint or facial scan.


Set up your mobile passcode 

  1. From your mobile device, open the Slack app.
  2. Follow the prompt to set a six-digit passcode that you'll use to access the Slack mobile app.
  3. If your device is compatible, follow the prompts to set up a fingerprint or facial scan to sign in.

Once your mobile passcode has been set up, the Slack mobile app will load and you’ll be able to access the workspaces in your Enterprise Grid org.
