Audit & Revoke Access After an AI Agent Uses Your Accounts

When an AI agent has used your accounts, you need to check what it could see and do, then remove its access. This guide shows you how to audit permissions, revoke them safely, and secure your accounts against future use. You’ll need access to your account settings and, ideally, a password manager to track what you change.

What You’ll Need

• Access to the email account you use for account recovery (to confirm changes).
• Your phone for two-factor authentication (2FA) codes, if enabled.
• A list of the services you use (email, social media, cloud storage, etc.).
• A password manager or a secure note to record changes (optional but recommended).

Step-by-Step

1. List every account the AI agent might have touched. Start with your primary email, cloud storage (Google Drive, Dropbox, OneDrive), social media, and any service where you’ve granted third-party access. If you used the AI to send messages, post content, or modify files, include those platforms.
2. Check your email for new sign-in alerts or verification codes. Look for messages from services you didn’t initiate. These often indicate that the AI agent logged in or attempted to. Open each alert and note the device, location, and time.
3. Review active sessions and devices. For each major account (Google, Microsoft, Apple, Facebook, etc.), go to Security or Privacy settings and find “Where you’re signed in” or “Active sessions.” Look for unfamiliar devices or locations. If you see one, sign out of that session immediately.
4. Inspect connected apps and third-party access. In the same security settings, find “Connected apps,” “Third-party access,” or “Authorized applications.” Review each entry. Look for anything you don’t recognize, especially with names like “AI assistant,” “automation,” or random strings. Revoke access by clicking “Remove” or “Revoke access” next to each suspicious app.
5. Check API keys and tokens. For developer-oriented services (GitHub, AWS, Google Cloud, etc.), go to API settings or IAM (Identity and Access Management). Look for keys or tokens that were created recently. If you see any you didn’t create, delete them. Also rotate existing keys if you suspect they were exposed.
6. Review email forwarding and filters. In your email settings, check for forwarding rules or filters that might be sending copies of your messages elsewhere. Remove any you don’t recognize. This is a common way for agents to exfiltrate data.
7. Change your passwords. For any account the AI agent accessed, change the password immediately. Use a strong, unique password for each account. Enable two-factor authentication (2FA) if you haven’t already.
8. Sign out of all sessions after changing passwords. Most services have an option to “Sign out of all devices.” Use it. This forces any lingering agent sessions to end.
9. Check your billing and payment methods. Look at recent transactions for any charges you don’t recognize. If you see any, dispute them with your bank or the service provider. Also remove any stored payment methods from the AI agent’s platform.
10. Monitor your accounts for a few days. After revoking access, keep an eye on your email and account activity for any new sign-ins or changes. If something still looks off, repeat the audit or contact the platform’s support.

Common Mistakes

• Only checking one account. If the AI agent had access to your email, it could have used it to reset passwords on other services. Audit all linked accounts, not just the one you think it used.
• Forgetting about API keys. Many people revoke app permissions but miss API tokens that are stored in code or configuration files. These can be used silently.
• Not changing passwords after revoking access. Revoking access only stops the agent’s token. If it saved your password, it can log in again. Change passwords for any account the agent touched.
• Ignoring email forwarding rules. A forwarding rule can send copies of your emails to an attacker’s address without you noticing. Always check this.
• Using the same password across accounts. If the agent got one password, it might try it on other services. Use unique passwords for each account.

Tips

• Use a password manager. It helps you create and store strong, unique passwords for every account, making it easier to rotate them after an incident.
• Enable two-factor authentication everywhere. Even if a password is compromised, 2FA can block unauthorized access.
• Set up login alerts. Most services can notify you via email or text when a new device logs in. This gives you early warning.
• Review permissions regularly. Do a quarterly audit of connected apps and sessions, even when you haven’t used an AI agent.
• Use a dedicated email for AI sign-ups. If you frequently try new AI tools, use a separate email address so a breach doesn’t expose your primary account.

Troubleshooting

• You can’t find the “connected apps” section. Try searching the help center for “third-party access” or “authorized applications.” Each service has a different name. If you still can’t find it, use the service’s support chat or contact form.
• You see an app you don’t recognize but can’t remove it. Some apps are required for core functionality (e.g., “Google Sign-In”). If you’re unsure, search the app’s name online. If it’s a known service you use, leave it. If not, try revoking and see if anything breaks.
• You changed your password but still see suspicious activity. The agent might have a stored session token that wasn’t invalidated. Use “Sign out of all devices” to force a logout. If it persists, contact support.
• You’re locked out of an account. Use the “Forgot password” flow. If you have 2FA enabled, you should be able to recover via backup codes or your phone. If not, contact the platform’s support and explain you’ve been compromised.
• You suspect the AI agent is still active. Check if the AI platform has a “connected accounts” section in its own settings. Revoke access there as well. Some AI tools let you disconnect integrations directly.

Frequently Asked Questions

• How do I know if an AI agent actually accessed my accounts? Look for unusual sign-in alerts, new devices in your session list, or unexpected changes to settings. If you didn’t initiate those actions, assume it did.
• What’s the difference between revoking an app and changing my password? Revoking an app invalidates that app’s access token. Changing your password invalidates all tokens and requires new login. Do both for maximum security.
• Can an AI agent access my accounts without me knowing? If you granted it permission (even accidentally), yes. That’s why regular audits are important.
• Should I delete the AI agent’s account entirely? If you don’t use it anymore, yes. But if you need it, at least disconnect all integrations and change your password.
• How often should I audit my connected apps? At least once a month, or after any suspicious activity. If you use many AI tools, consider doing it more frequently.
• Will revoking access affect my other apps? Only the app you revoke. Other connected apps remain unaffected. However, if you sign out of all sessions, you’ll need to log in again on all your devices.
