How to revoke third-party app access from Google Account

If you’re a Google user, you’ve probably had to connect a third-party app to your account. For example, if you’ve even signed in with Google on another app, you’ve given that app access to your Google account.

Google has one of the richest ecosystems, allowing third-party apps to leverage their API to build on top of Google. For example, OneCal leverages the Google Calendar API to sync Google Calendars and provide scheduling links.

Depending on the functionality of the app you’re using, it might access your Calendars, your contacts, YouTube, and much more.

Although third-party apps are rigorously tested and approved by Google, sometimes it’s better to revoke their access from your Google Account. Some reasons why you should revoke the third-party app access from your Google Account are: that you might not use the app anymore, the app is compromised, or the third-party app is conflicting with another third-party app.

Whichever your case is, in this article, we’ll explain how to revoke third-party app access from your Google Account.
