Reset admin password

Sometimes you installed Open source software such as Moodle in local host. You forgot the admin password and smtp password reminder is not set properly. You can access MySQL database, but password is md5 encrypted.

There is one way to solve this. In password field enter:
d41d8cd98f00b204e9800998ecf8427e 
Because MD5("") = d41d8cd98f00b204e9800998ecf8427e, so now your password is a empty string.
So you can login as admin without password. And reset password after login.

You can also directly  reverse md5 encrpted password online via:

Then you know the admin login password.
