Apps You Connected Months Ago May Still Have Access to Your Account

Introduction

Think about the last time an app asked you to “Sign in with Google” or “Sign in with Microsoft.” You probably clicked the button, approved a few permissions, and went about your day.

What you may not realize is that the app could still have access to your account months or even years later.

These connections can be incredibly convenient, but they can also create a cybersecurity risk that is easy to forget, especially because you rarely see them.

What Are You Actually Approving?

When you connect an application to another account, you may be asked to give it permission to access certain information.

In many cases, it makes sense. A calendar app might need access to your calendar, while a scheduling tool may need your email address and contacts. A photo-editing service might ask to access photos stored in your cloud account.

The problem comes when we click Allow without actually looking at what we’re allowing.

An app might request permission to read your email, access files, view contacts, or perform other actions within your account. Once you approve those permissions, the connection can remain active until you revoke it.

How often do you do spring cleaning on your programs?

Your Password Isn’t Always the Key

These connections commonly use something called OAuth, which lets one service access another without using your actual password.

That is generally a good thing! Unfortunately, it also means changing your password may not necessarily remove every third-party connection that you previously approved.

If a connected application becomes compromised, an attacker may try to abuse the permissions that application already has. In other words, they may not need to steal your password if you already gave the app another way into your information.

What Is Consent Phishing?

Cybercriminals can also intentionally abuse this process through an attack called consent phishing.

Instead of creating a fake login page and stealing your password, the attacker creates a malicious application and convinces you to authorize it. For example, you might receive a message saying someone shared a document with you. You click the link, legitimately sign into your account, and then see a screen asking you to approve its access.

The login page may even be real. The dangerous part is the permission request that comes afterward. If you click Allow, you could give the malicious application access yourself.

Even legitimate applications can become a problem when you stop using them. Maybe you connected a scheduling app two years ago, tested an AI tool for a week, or authorized an application for a project that ended months ago. If you never revoked those permissions, some connections may still exist.

Take time to review what apps you have installed and what they can do inside your accounts.

Take a Look at What’s Connected

Every few months, review the applications connected to your important accounts.

When you do, ask yourself:

• Do I recognize this application?

• Do I still use it?

• Does it really need the permissions it has?

• Is this application approved for work use?

If you don’t recognize a program, don’t simply leave it there because you’re afraid removing it might break something. For a work account, contact your IT department and ask them to investigate it.

For personal accounts, revoke access to applications you no longer use or trust.

Conclusion

We spend a lot of time worrying about who knows our passwords, but passwords are no longer the only way applications access our information. Every Allow button matters too.

Pay attention when an application asks for access, and periodically clean out connections you no longer need. It only takes a few minutes, but it can close doors into your accounts that you completely forgot were open.

Sometimes good cybersecurity isn't just about stopping someone from getting access; it's also about remembering who you already gave it to.
