Hey there,
Are you still having issue with this?
I think it will be much more difficult to reset the password without Database access, I can’t think of many ways to change it without CRM / DB access.
Do you know if any other users have access to the CRM?
If they are admin-type users, they could reset your password from within the CRM
Otherwise, I found this thread: Forgotten admin password
In which amariussi describes resetting the password via creating a PHP script
Are you able to reset through this method?
