How to unlock a locked user from the command line

After ten failed login attempts a user gets in a locked state.

To unlock a locked user:

1. SSH into your GitLab server.

2. Start a Ruby on Rails console:

   ## For Omnibus GitLab
   sudo gitlab-rails console -e production
   
   ## For installations from source
   sudo -u git -H bundle exec rails console -e production

3. Find the user to unlock. You can search by email or ID.

   user = User.find_by(email: 'admin@local.host')

   or

   user = User.where(id: 1).first

4. Unlock the user:

   user.unlock_access!

5. Exit the console with Ctrl+d

The user should now be able to log in.
