Understand what kind of passkey you are dealing with
Google Account passkeys are not all managed in the same place. The removal path depends on how the passkey was created. A passkey you created manually in your Google Account is listed with your other passkeys and can be removed from account settings. A passkey automatically created by an Android device is tied to that device and is handled through device management instead.

For a passkey automatically created by an Android device, Google directs users to Manage all devices and sign out of that device. Source
Decision table: match the situation to the right action
| Situation | Where the passkey lives | First action |
|---|---|---|
| You manually added a passkey to your Google Account | Google Account security settings | Remove the passkey under Security and sign-in, then Passkeys and security keys |
| The passkey was created automatically by an Android device | The Android device and its Google Account link | Go to Manage all devices and sign out of that device |
| A credential-manager prompt keeps appearing after removal | The credential manager on the device | Check the credential manager’s saved entries, not just the Google Account |
Manual verification checklist
- Confirm the passkey type: was it manually created in your Google Account, or did an Android device create it automatically?
- For a manual passkey, open Security and sign-in, then Passkeys and security keys, and remove the correct entry.
- For an Android-created passkey, open Manage all devices and sign out of the device you no longer control.
- After removal, check the credential manager on any device where the passkey was used, because a saved entry may remain there.
- If you still see prompts, review the credential manager’s stored credentials rather than assuming the Google Account change failed.
Removing a passkey from the Google Account may not remove a saved credential-manager entry; persistent prompts should be checked in that manager. Source
Removing a passkey is a credential-removal task, not a guarantee that every trace of the device is gone. It does not by itself prove the account is secure, and it does not replace reviewing active sessions or other sign-in methods. For broader account-audit guidance, see our related methodology articles on session lists and public-footprint checks.
What TraceSeek can and cannot do
TraceSeek is a username search app that checks 3,000+ platforms for public username matches. It cannot change platform settings, access private content, prove ownership, or find all accounts by phone or email. A public username match is a lead, not proof of ownership. A first scan is free and typically takes 20-30 seconds.
