I have several gmail accounts for different purposes. When logging in to access any of my accounts, the drop-down list that appears on the sign-on page comes up with six accounts. A couple of them are correct and when clicked on take me to the correct account. But there are two others that I have to manually change in order to access those accounts. Also, the passwords associated with those accounts are old passwords and I always have to type in the more recent password. How do I update the drop-down list of email addresses and the related disguised passwords that appear? Also on that list is an account I do not use any more and would like to have it removed from the list. How can I make these changes?
Which browser do you use? In Firefox for example, go to Edit -> Security -> Saved passwords, search for google, and delete all entries for your google accounts. Then log in with your new accounts and confirm that you want your browser to save the new passwords.
