Changing Deafult 'Sign in As a Different User' in Google

Hi Sitepoint!
Sorry if this is in the wrong forum. Not sure where it should go, if not here.

I’d like to know how I can change what e-mail/username and password deafult pops-up when I click on ‘Sign in As A Different User’

Right now when I click it, an old e-mail that I don’t use anymore pop-ups. I’d really like to be able to interchange between my two accounts across all of Google’s services, and not have to type it in again every time.

Thanks for your help!

It’s probably stored in your browser, so look for the option that lets you delete saved forms and passwords.
