Alright! I understand that there is a custom wordpress login url. Also you need to login to a user’s profile. If that’s the case, I suggest a simple hack(If you legally have rights to access/modify the database). Try this:
- Go to cpanel and login to phpmyadmin and open the database for your website/blog.
- Find ‘wp_options’ table and search for a record ‘active_plugins’. Now remove everything in the value to deactivate all plugins(Some plugin may have changed you login url, So this step.)
- Then go to ‘wp_users’ table and you’ll find all the user details here. You cannot change password as it is encrypted. So change the user email to a working email. Save the record.
- Now go to the default wordpress login url(http//www.yourdomain/wp-admin). Press ‘Lost password’ and Enter the email you’ve entered for the user. You will get a confirmation email. Change the password. Done!
