If an unfamiliar app, integration, or automated agent appears to be using your account, secure the account through the provider’s official app or website, revoke access you do not recognize, and check whether money, personal information, or your device may also be at risk. Account logs may show unusual activity without identifying whether a person, app, or agent initiated it, so focus first on stopping access rather than guessing who was responsible.

1. Start from a trusted channel

Open the provider’s official app or type its known website address yourself. Do not follow sign-in links or call phone numbers in unexpected messages about the incident. If financial information may be involved, contact the bank, card issuer, or payment service through its official app or website, or use the number printed on a statement or payment card. Do not give an unexpected caller your password or verification code, or let them remotely access your device. The FTC’s scam guidance recommends using known official channels.

2. Secure the account you can still access

  1. Change the password. Set a strong, unique password for the affected account. Change it on any other account where you reused it. The FTC recommends changing passwords after a scam or account compromise. FTC: What To Do if You Were Scammed.
  2. Turn on two-factor authentication. Enable it in the account’s security settings, especially for email, financial, and other sensitive accounts. The FTC explains available methods, including security keys, in Use Two-Factor Authentication To Protect Your Accounts. Check that any security key or method you choose is supported by your provider.
  3. End other sessions if the provider allows it. Use the account’s sign-out-all-devices or session-management control to remove access from other devices. The FTC includes signing out of all devices in its recovery advice for hacked email and social accounts: How To Recover Your Hacked Email or Social Media Account.
  4. Check recovery contacts. Make sure the recovery email addresses and phone numbers belong to you. Remove or correct details you do not recognize.

3. Find and remove the access route

Review sign-ins and account changes

Check recent sign-ins and account changes for unfamiliar sessions, altered recovery details, or messages and posts you did not send. The available history depends on the provider and may not show every action. For example, Microsoft’s Recent activity page covers the previous 30 days for Microsoft accounts, but Microsoft cautions that it does not show all account activity. That window and limitation are specific to Microsoft, not a general rule for other services.

Inspect connected apps and permissions

Look for connected apps, integrations, or permissions you do not recognize or no longer need. Revoke access where the provider gives you control. Removing a permission can disrupt an app’s features; Microsoft warns that “Removing permissions or accounts may break some app functionality.” Its My Apps portal guidance also distinguishes permissions you granted from administrator-consented access. If an organization granted the permission, ask its administrator to remove it.

Consider tokens and work accounts

A password change may not revoke every app permission or access token. For social-media accounts, CISA advises limiting third-party app access, reviewing app privileges, and monitoring unusual activity and permission changes. It also notes that compromised API keys or tokens can allow impersonation without the account password. See CISA’s social-media account guidance. If this is a work or school account, report the activity to your administrator; centrally managed permissions or integrations may require their action.

4. If you are locked out, use official recovery

Go directly to the provider’s official account-recovery process if your password no longer works or your recovery details have changed. Avoid recovery links sent by strangers or unsolicited support contacts. After access is restored:

The FTC’s hacked account recovery guidance covers recovery steps for email and social accounts; other providers have their own procedures.

5. Check your device only if device access is plausible

If you think the agent was installed on or operated through your phone or computer, update its security software and run a scan; remove any problems the software identifies. Then change passwords and enable two-factor authentication. These are steps the FTC recommends when someone has given a scammer access to a device, not evidence that unfamiliar account activity by itself means your device is infected.
