How to See (and Remove) the Apps and AI Agents Connected to Your Google, Microsoft and Apple Accounts

When you connect an AI agent to your email or calendar, you usually see a screen like “ChatGPT wants to access your Google Account” with a list of permissions and an Allow button. Clicking Allow doesn’t give away your password, it gives the app a token, a kind of key, to specific parts of your account. That’s good design.

The catch: the key keeps working until you revoke it. Most people have dozens of forgotten keys handed out to apps, games, browser extensions and, increasingly, AI tools. Every one is a door. Here’s how to check them.

Why this matters more with AI agents

AI agents are unusually capable guests. An agent with access to your email can read it, and depending on the permissions, send from it. Because agents also read content written by strangers, they can be targeted by prompt injection. The less an agent can reach, the less can go wrong. Reviewing connections is the single most effective habit for staying in control.

Google

Google’s help page is titled “Manage links between your Google Account & apps from other developers.”

1. Go to myaccount.google.com/linkedapps and sign in.
2. You’ll see apps grouped by how they’re connected.
3. Select an app and choose See details to review what it can access.
4. Remove access if you no longer use or recognise it, and confirm.

Google distinguishes two kinds of link:

Type	What it means	What removing it does
Sign in with Google	You use your Google account to log in to that app	Stops automatic sign-in; your data stored with the app stays there
Has access to your Google Account	The app can access specific data, such as Gmail, Calendar or Drive	The app can no longer access that data, and related features may stop working

The second type is the one to scrutinise. Look especially for anything with access to Gmail, Drive or Contacts.

Microsoft (personal accounts)

For Outlook.com, Hotmail, Xbox and other personal Microsoft accounts:

1. Go to microsoft.com/consent and sign in.
2. You’ll see a list of apps and services connected to your account.
3. Select one to see which data it can access.
4. Choose Remove these permissions and confirm.

Microsoft (work or school accounts)

If your email is provided by your employer or school through Microsoft 365:

1. Go to myapplications.microsoft.com.
2. Hover over an app and select the … menu, then Manage your application.
3. Review the permissions. The top section shows permissions you granted; you can Revoke permissions there.
4. Permissions granted by your administrator appear separately and can’t be removed by you, ask your IT team if something looks wrong.

For work accounts, also check your organisation’s rules before connecting any AI tool at all.

Apple

Apple’s equivalent is Sign in with Apple, which lets you log in to apps with your Apple Account (and optionally hide your real email address).

On iPhone or iPad:

1. Open Settings and tap your name.
2. Tap Sign in with Apple (on some versions under Sign-In & Security).
3. Choose an app, tap to stop using your Apple Account with it, and confirm.

On the web: go to account.apple.com, then Sign-In and Security > Sign in with Apple.

Apple notes that if a developer has several apps linked to one sign-in, stopping use with one affects all their apps. If you used Hide My Email, you can manage forwarding separately in iCloud settings.

Don’t forget the AI apps themselves

Connections go both ways. Inside ChatGPT, Gemini, Claude, Perplexity and similar tools there’s usually a Connectors, Apps or Connected apps section listing which of your services the AI can reach. Review it too, and switch off anything a current task doesn’t need.

Also check scheduled tasks in those apps. A forgotten weekly task can keep using its access long after you’ve stopped reading the results.

What to remove

Remove an app’s access if:

• you don’t recognise it;
• you haven’t used it in months;
• it has broader access than its job needs (a quiz game with access to your Gmail, say);
• it’s an AI tool you tried once and never went back to.

Keep access for tools you actively use, but re-check what they can do. If an app offers a narrower permission (read-only instead of read-and-send), prefer that.

Make it a habit

Put a recurring reminder in your calendar every three months: “Review connected apps. Google, Microsoft, Apple, AI tools.” It takes five minutes and closes doors you forgot you’d opened. For the full picture of agent permissions, see are AI agents safe to use?
