Devise provides you with this functionality already. Have a look at https://github.com/plataformatec/devise/wiki/How-To%3a-Allow-users-to-edit-their-password — IngoAlbers, Oct 08 '15 at 20:28

You want Devise's valid_password? method.

> user = User.find(1)
> user.valid_password?('invalidpassword')
=> false
> user.valid_password?('therealpassword')
=> true

Devise already provides you with this functionality. It should probably work out of the box using the edit_user_registration_path.

Have a look at https://github.com/plataformatec/devise/wiki/How-To%3a-Allow-users-to-edit-their-password to find some more information.
