So you have multiple Google accounts that you work with on a regular basis? Maybe a Gmail account for work and one for private messaging? Or a work and home Google+ or YouTube account? Or maybe your whole family is using one PC and sharing a single account on that PC?
If that is the case you may appreciate the option to add multiple accounts to Google’s sign in page. When enabled, it lets you stay signed in to all accounts and displays a selection screen on the sign in page that basically lets you select the account that you want to log in with.
First thing that you need to do is enable the feature here on this official Google account page. It displays a list of all current accounts, and an add link to add another user account to Google. You can add as many Google accounts as you like to the service. Each time you do that, you are asked to enter the associated email address, e.g. the gmail address or the email from another service, and the password.
Once you are done you can click on the email address at the top right to switch between accounts. When you select sign out, you are logged out of every account. On the next log in, you are asked to pick one of the available accounts and enter the associated password to complete the sign in process and access that account’s information on services such as Gmail, Google+ or YouTube.
This works best for accounts that are all associated with you obviously, since you do not necessarily want friends or family to access your private or work related accounts when they use the computer. To avoid this, I suggest you create accounts for each user on the system.
If you do not want to use the multi sign-in option anymore, you can disable the account chooser again on this page to do just that.
You can alternatively remove accounts by clicking on the edit button in the account list to do so. This option is only available if you are not currently logged in.
There are situations where you should not mix your account with someone else’s. Say you are at a friend’s house and want to check your Gmail emails. Instead of joining your account with the Google account of your friend, you could do one of the following things instead:
- Ask your friend to log out of Google so that you can log in. Or ask for permission to sign out of the account.
- Use the web browser’s private browsing mode if your friend does not want to be logged out.
- Use a different web browser, or a different operating system account if available.
Remember to log out of Google whenever you are finished working if you are not working on your own computer. Google notes that you may log into some of their services and third party services without the need to supply a password to do so. The only way to prevent your friends, family or co-workers from accessing your account accidentally or on purpose is to sign out whenever you are not working on the computer.
