Lost phone or new phone? Revoking access¶

Each device has its own access, so you can lock out a single phone without affecting your other devices.

Nextcloud (calendar, contacts, files)¶

Sign in to https://<cloud-address> on a computer.
Click your profile picture → Settings → Security.
Under Devices & sessions, find the phone and click ⋯ → Revoke. Both the Nextcloud app and the calendar/contacts sync appear here (often as separate entries).

Delete the app password of that phone, as described in App passwords.

If you used your mailbox password on the phone instead: change your password immediately and update it on all other devices.

Lost or stolen?

Please also tell us if a phone is lost or stolen, so we can check for anything unusual.
