Apps with access to your account
On the Apps with access to your account page, you can see a list of sites and applications. These are sites and applications to which you’ve granted permission to access your Google Account, and you can see on this list to what parts of your account they have access.
For example, you might have downloaded an app that helps you schedule workouts with friends. This application might have requested access to your Google Calendar and Contacts to suggest times and friends for you to meet up with.
There are several levels of access an application can have to your Google Account, but here are few examples:Full account access
When you give an app full account access, it can see and change nearly all information in your Google Account. But even with full access, an app can't:
- Change your password
- Delete your account
- Pay with Google Wallet on your behalf
Before you give an app full account access:
- Make sure the app is installed on your computer, phone, or tablet.
- Make sure you trust the app.
If you've granted full account access to an app you don't trust or recognize, we recommend that you revoke this permission by clicking Remove access.
Tip: Certain Google applications may be listed under full account access. For example, you might see that the Google Maps application you downloaded for your iPhone has full account access.
These apps have access to basic data from your account, like your name, email, gender, or country. You might also see that the app can "Sign you in using your Google Account." That means that you can sign in to these apps with your Google username and password as long as you’re signed in to Google, saving you the hassle of remembering new passwords or creating a new account.
Permissions for some apps and sites might include read and write access, which means that they can post information about your activity on their app or site to Google products you use. For example, you have an app on your phone that lets you track how far you run. If this app has read and write access to Google+, it can post the number of miles you run to your Google+ page.
