how to unloack user devise rails

To unlock a user in Devise for Ruby on Rails, you can follow these steps:

1. Open the terminal and navigate to your Rails application directory.
2. Open the user model file (usually user.rb) located in the app/models directory.
3. Look for the line that includes :lockable in the devise method call. It should look something like this: devise :database_authenticatable, :registerable, :recoverable, :rememberable, :validatable, :lockable.
4. Comment out or remove the :lockable option from the devise method call.
5. Save the changes to the user model file.
6. Restart your Rails server to apply the changes.

By removing the :lockable option, you are disabling the lockable feature in Devise, which allows users to be locked out after a certain number of failed login attempts.

Please note that unlocking a user in Devise may have security implications, as it removes the protection against brute-force attacks. Make sure to consider the security implications before making this change.
