My Problem
I must have turned on google to autofill for a login on my site, however it is trying to now autofill that login data whenever I want to edit
Sometimes even autocomplete=off would not prevent to fill in credentials into wrong fields, but not user or nickname field.
Fix: browser autofill in by readonly-mode and set writable on focus
(focus = at mouse click and tabbing through fields)
Update: Mobile Safari sets cursor in the field, but does not show virtual keyboard. New Fix works like before but handles virtual keyboard:

Explanation: Browser auto fills credentials to wrong text field?
@Samir: Chrome auto fills any input with a type of password and then whatever the input before it is
Sometimes I notice this strange behavior on Chrome and Safari, when there are password fields in the same form. I guess, the browser looks for a password field to insert your saved credentials. Then it autofills username into the nearest textlike-input field , that appears prior the password field in DOM (just guessing due to observation). As the browser is the last instance and you can not control it,
This readonly-fix above worked for me.
