Recover lost or hacked WordPress password from PHPMyAdmin / MySQL.

Imagine someone somehow manages to break into your WordPress dashboard, and changes it’s password and email. If you request a “Forget Password”, the reset password link will be mailed to the new email, not to your email. The result will be – you losing control over your WordPress-powered site. I think that’s enough to picturize that traumatic situation.
