If you need to sign out of your Claude.ai account across all devices, you can do this through your Account Settings on the web version of Claude.ai. This is particularly useful if you've forgotten to log out on a shared device or suspect unauthorized access to your account.
*Note that this option is not currently available in the Claude mobile apps for iOS or Android.
To log out of all active sessions:
Visit Claude.ai in a web browser
Sign in to your account
Click on your initials in the lower left corner
Select "Settings" from the menu
Navigate to the "Account" section
Click the "Log Out" button
Confirm your choice when prompted
This action will immediately sign you out of your account across all devices where you were previously logged in, including:
Web browsers
Mobile devices
Desktop applications
To regain access to your account on any device, you'll need to authenticate again using either Google login or a login link sent to your email address.
Unable to access your account?
If you're unable to sign into your account to log out of all sessions, contact our Support team by clicking on the message icon in the bottom right of any Help Center page (more on this here).
