An account takeover means someone else has gained access to an account that should be under your control. Signs may include unfamiliar messages, changed recovery details, or sessions you do not recognize. The goal is to recover control and understand what the unwanted access allowed.
Understand the idea
Start with the service’s official recovery route. Secure the email account used for recovery if it is also affected. Review active sessions, recovery addresses, extra sign-in methods, and connected applications. A password change is important, but it may not remove every existing route into the account.
- Regain
Use the provider’s official recovery route.
- Remove
End unauthorized sessions and reverse unwanted access changes.
- Review
Check what the account did while someone else controlled it.
A practical example
Imagine friends receiving unusual messages from your social account. You recover it through the platform, change the password, end unfamiliar sessions, and remove an unknown connected app. You also check whether the same password was reused elsewhere and warn contacts through a trustworthy route.
What to do next
- Secure the recovery email account if it may also be affected.
- Follow the provider's official account-recovery route; do not pay an unknown recovery specialist.
- Replace the password with a unique one and review supported MFA or passkey settings.
- Remove unfamiliar recovery addresses, phone numbers, factors, devices, sessions, and application grants as the service allows.
- Inspect changes made during the compromise, such as inbox forwarding, profile edits, stored payment changes, or sent messages.
How to check the result
Confirm that recovery details belong to you and that unwanted access no longer works. Keep a timeline and report unauthorized purchases or disclosures to the relevant provider.
I can sign in again. What should I check next?
Review recovery email and phone details, sessions, connected apps, and service-specific changes such as mailbox forwarding. Check linked accounts if the same password was reused.
