When changing the password from web interface it always sets the same value to both password/username, so if I set username "Admin" and Password "12345" it saves settings with Username "12345" Password "12345"
It is your autofill feature of your browser. Tell your browser not to remember the password for the page and it won't automatically populate it. I have seen this before.
