I have autofill saved for my Chrome-Gmail account. I accidentally typed in the password field. Now the password field is being populated with the wrong info I typed. Chrome is not reverting to the original password. It has been over a year since I typed in the password field manually so I don't remember what the dots were. Is there a way to force chrome to populate the field with the correct password that was last used to successfully login.
