Can't login to my Drupal website admin! I can't login My drupal website (D 7.23) now.
I have changed the password and tried to login back, but still the problem exists. After I reset the password by using the one time password and can log in, but when we log out and try again to login, it will be a failed one.

Please help me to solve it.

Drush can generate a one-time login link.

drush uli


Reset password

drush upwd --password="givememypasswordback" admin
