What is the purpose of a session lock

Active session lock prevents the same browser profile from being opened on multiple devices simultaneously. This protects your data, fingerprint settings, and sync status, avoiding confusion.

Why Session Locks Are Useful

Protect data: Avoid losing cookies, form data, or unsaved work
Prevent sync issues: Prevent profile sessions from conflicting across devices
Maintain fingerprint consistency: Avoid detecting conflicting profile behavior

How Session Locks Work

When the configuration file is running on Device A, it cannot be opened simultaneously on Device B. If you try to open it, you will see a padlock icon instead of the start/stop button.

How to Unlock or Stop an Active Session

Normal Stop

Click the 'Stop' button in the profile list. This allows you to safely end the session and unlock the profile.

If the configuration file remains locked

Hover the mouse over the lock icon, then click "Unlock" or click "Unlock All" at the top right of the dashboard
Refresh the page – the padlock will disappear

If you do not see the 'Unlock Profile' button

Stop all running profiles
Disconnect the agent
Delete the .lock files in the /%username%/mlx folder

/%username%/mlx

.lock

Refresh the dashboard
Reconnect the agent
You should now see the "Unlock Profile" button – click it to unlock

Professional Tips

Always use the Multilogin 'Stop' button to close profiles
If problems occur, make it a habit to refresh the dashboard

Frequently Asked Questions

Why is my configuration file still locked after closing it?

It may have crashed or not closed properly. Please use the above unlocking steps to fix it.

Can I force open the profile on another device?

No — this is intentional. This is to ensure the security of your data and identity.

What does the padlock icon mean?

This means the session is still running somewhere – or Multilogin thinks it is running.
