Assuming you've lost your password to a wordpress installation, but you still have access to your host's panel and/or database, here's how to reset your password:
- Navigate to the Users Table
- edit the row containing your username.
- locate the userpass field
- Replace with a new password hash using md5()
echo -n NEWPASSWORD | md5sum
In Windows Powershell,
"NEWPASSWORD" | Get-Hash -Algorithm MD5
