Despite its simplicity, logging into other apps using a Google or Facebook account is far from recommended by cybersecurity experts. The reason is simple: A little carelessness is all it takes to leak a large portion of user data.

Earlier in October, Facebook warned one million users that their accounts could be hijacked by 400 pieces of malware designed to spoof their login credentials. This happened because of fake buttons.

According to a technical expert and columnist Washington Post It’s best to create a unique account for each website and app you want to log into, and ideally save a password for each, says Jeffrey Fowler.

This is because of the vulnerability of the sensitive pressure of permissions granted to websites and apps that are rarely read by users. As with Facebook, there can be time-saving login buttons, for example, fake techniques to steal personal information.

The risk also applies to those who do otherwise. So, anyone who hacks a Google or Facebook account will also have access keys to those sites. Another reason is that companies can monitor online behavior and view usage of these platforms using their Google and Facebook accounts on third-party websites.

In late August, former Google engineer Felix Krause determined that Facebook and Instagram’s parent company, Meta, was able to track every step of users clicking sites on its social networks. That’s what we’re talking about in this report.

Check connected apps and websites

When asked a Google spokesperson, he said users have “choice and control” when choosing which details of data sharing they want to access. But the question arises: is this information understandable by users? Who reads the fine print?

Sign in to your Google account and open Permission Center. All third-party programs and access points will be there. When you click on the name of the site, the “Revoke access” button will appear. Click on the one you want to disable.

Sign in to Facebook and go to Apps & Websites settings. There, just choose which unnecessary links you want to remove. Facebook automatically disables unused links after 90 days.
