To remove a passkey from a Microsoft account, it must be removed both from the account’s security settings and, if applicable, from the Windows device where it is stored.
For a personal Microsoft account:
- Go to your Microsoft account Advanced Security Options page at https://account.live.com/proofs/manage and sign in.
- Under Ways to prove who you are, find the passkey you want to remove.
- Select that passkey and choose Remove.
For a work or school (Entra ID) account:
- Go to Security info at https://mysignins.microsoft.com/security-info and sign in.
- In the list of sign-in methods, select Delete next to the passkey you want to remove.
- After deleting it from Security info, remove the corresponding passkey from your device (for example, from Windows passkey settings as below).
To remove a device-bound passkey stored locally on Windows 11:
- Open Settings on the Windows device.
- Select Accounts > Passkeys (or use the shortcut Passkeys).
- In the list of saved passkeys, locate the passkey to remove.
- Select … (More) next to it and choose Delete passkey.
If the passkey is synced via another provider (for example, Microsoft Password Manager in Edge or a third‑party credential manager), manage and delete it from that provider instead.
