Signing-in to Google Apps

Common questions about signing-in with Google Apps

Google maintains a page of Known Issues with Google Accounts; the sections you see are generated on-the-fly depending on whether you are logged in or not. To see the sections for transitioned accounts and multiple sign-in you will need to be logged in to your Google Apps @ Cambridge account; if you are not logged in to this account you will see the generic Known Issues page, which does not have the information about transitioned accounts.

  1. What happened to Google's authentication architecture?

    Google changed the way that authentication to Google Apps domains works. Essentially they sorted out a confusing situation in which a single email address could be associated with both a Google Apps account and a standard Google account. The resulting simplification makes Google Apps accounts work more like standard Google accounts, was in the interests of users and Google alike, and allows Google to move forward with a number of new services.

  2. Why can't I sign in to my Google Apps @ Cambridge and my personal Google account at the same time?

    Because of the way Google's authentication works it is not possible to do this at the same time from the same browser. If you really need to do this you will either have to use different browsers (or possibly different sessions in the same browser) or use Google's multiple sign-in service. You can enable multiple sign-in from:
    Settings > Google Account settings.

  3. I'm using multiple sign-in and sometimes I can access an app and sometimes I can't. What's going on?

    Starting from scratch, the first account you log in to becomes your default account. When you access a new app you are initially authenticated under this account. If this account doesn't have access to the app (e.g. you wanted Blogger but you logged into your Google Apps @ Cambridge account first) you will get a 'Service is not available' message.

    If you want to use your personal Google account and your Google Apps @ Cambridge account at the same time it may be better to log in to your personal account first.

  4. I had a Google Account using my address and I now have a Google Apps @ Cambridge account. I don't want both. Can I delete one?

    • If you decide that you don't want the personal Google account that uses your address you can delete this yourself. See Google's help pages on account deletion.

    • If you decide that you no longer want your Google Apps @ Cambridge account then email the UIS Service Desk ( and ask for the account to be deleted. Note that deleting the account will immediately and irrevocably destroy any information (i.e. your Google Apps @ Cambridge calendar(s)) stored in that account.
