After setting up a passkey on a security key, you can remove it anytime from your Microsoft account if it is compromised or missing.
You must remove a passkey from a security key if your security key is lost or stolen so that nobody else can use your security key to access your accounts. If you suspect your passkey has been compromised, remove it immediately to prevent further unauthorized access to your accounts.
