Reset Password will not work

All,
I have been trying to change my password from ‘myPHPAdmin’ pretty much all day and I can’t get it to change.

I used these instructions with no luck: https://www.tamba2.org.uk/wordpress/phpmyadmin/

I follow the instructions, put in a new password in the myPHPAdmin database hit the Go button, go to the login screen and try to enter my new password and it does not work.

Can someone please help me?
