Use your Google Account to sign in to other sites or apps
You can use your Google Account to sign in to third-party sites and apps, which means you won't have to remember individual usernames and passwords for those sites and apps.Using Google to sign in to a third-party site or app
Some sites and apps offer Google Account sign in as an option. This feature allows you to sign in and create an account on that site or app using your Google Account information.
You should grant permission only if you trust the site or app.
Google sends a random code to third-party sites or apps to enable you to sign in with your Google Account. This code doesn't reveal any personal information. These sites or apps are also able to request the name, email address, and profile picture associated with your account.
When you sign in to a third-party site or app using your Google Account, the service may ask Google for the name, email address, and profile picture associated with your account. The site or app could also ask for access to data in any of the Google services you use. You should grant permission only if you trust the site or app.
If you've used Google to sign in to a third-party site or app, you can revoke future access to your information at any time. Just follow these steps:
- Sign in to My Account. If you use an account through your work, school, or other group, sign in and visit the Manage Account page, and replace "example.com" with your domain name.
- In the "Sign-in & security" section, choose Apps with account access.
- Choose Manage apps.
- Choose the site or app you no longer want included and choose Remove.
Note: The third-party site or app may retain information from the Google Account you used to access it and/or the Google Account information you allowed it to access. Google is not affiliated with third-party services that ask for authentication. Google simply provides sign-in technology to these sites.
Facebook does not use Google Account sign-in, therefore changing your Google Account password will not change the password for your Facebook account.
Important: Google does not review or endorse websites and applications that allow you to sign in with a Google Account, and takes no responsibility for those sites. If you do not trust the site or app that is requesting access, you should not confirm that you want to use your Google Account to sign in.
