All three major tech giants—Facebook, Google, and Apple—offer a quick and easy method of registering and logging in to websites. These features allow websites and apps to access certain data from your Google and Facebook accounts while remaining simple and convenient to use.

Your username, email address, legal name, phone number, and friend lists are just a few examples of personal data. Regardless of the platform, there are times when you don’t want to allow access to certain websites and apps. A website you once logged into just to read an article or an app you haven’t used in a very long time are some examples of this scenario. Even if you change it, they will still have access to your data on each service.

Fortunately, you can quickly identify which websites have access to your information and easily revoke those permissions at any time. Here we will discuss ways to revoke such permissions for different platforms.

For Apple:

The Sign in with Apple button is a little different from the other sign in options. This way, you have more control over your data. Apple only allows other people to see your name and email address, but you can use any nickname you like. Apple also claims that it does not monitor your usage.

Steps to follow:

Open the Settings app on your iPhone, iPad, iPod Touch, or Apple Watch, then tap your name.
Go to “Apps that use Apple ID” under “Password & Security” on the next screen.
You will then be taken to a list of approved applications.
Select “Stop using Apple ID” by selecting the website in question.

For Google:

Your account settings control permissions for Google authentication.

Steps to follow:

Visit the Google home page.
To sign in to the account you want to edit, click Sign In in the upper right corner.
If you do, your profile picture will be displayed on the home page instead of the login button.
Select “Manage your Google Account” by clicking on your profile picture.
On the next page, click Security on the left sidebar, then scroll down to the Sign in to other sites area.
Click Sign in with Google below it.
You can get a list of all the apps and websites that authenticate with your Google profile.
Entries in the list can be clicked to reveal the data that each site has access to.
However, you cannot remove some permissions. Permissions can only be fully revoked using the Remove Access button.
For Facebook:

Click on your profile picture at the top of the left sidebar after logging into your account.
Under Settings & Privacy, go to Settings.
Scroll down a bit and tap on Apps & Websites.
Now in this section you can learn about how your data is shared and which apps and websites have access to it.
You can select “Remove” for each item in the list to prevent it from accessing your Facebook information.
