+# How to unlock a locked user
+
+Log into your server with root privileges. Then start a Ruby on Rails console.
+
+Start the console with this command:
+
+```bash
+gitlab-rails console production
+```
+
+Wait until the console has loaded.
+
+There are multiple ways to find your user. You can search for email or username.
+
+```bash
+user = User.where(id: 1).first
+```
+
+or
+
+```bash
+user = User.find_by(email: 'admin@local.host')
+```
+
+Unlock the user:
+
+```bash
+user.unlock_access!
+```
+
+Exit the console, the user should now be able to log in again.
