Windows and Microsoft sites are asking for a security key because a security key sign-in method is registered on the Microsoft account and/or set as the default sign-in option. To stop being prompted for a security key, remove it as a sign-in method and use another verification method instead.
Use these steps:
- Sign in with another verification method
- When the prompt appears and asks for a security key, look for a link such as Sign in another way.
- Choose a different method that is already set up (for example, text message, email code, or Microsoft Authenticator) and complete sign-in.
- If Sign in another way does not appear, no other methods are configured. In that case, contact the account administrator or support to get temporary access and then add more methods.
- Remove the security key sign-in method from the Microsoft account
- After signing in, go to the Microsoft account Security page: https://account.microsoft.com/security
- Select Manage how I sign in (or More security options / Advanced security options, depending on what is shown).
- Under Ways to prove who you are, locate any Security key entries.
- Remove the security key entries so they are no longer offered as a sign-in method.
- Add and prioritize other sign-in methods
- Still on the Security page, add at least two other methods (for example, phone number for SMS, alternate email, or Microsoft Authenticator app) so that two-step verification can use them instead of a security key.
- If two-step verification is enabled, ensure there are multiple working methods so that Sign in another way always has options.
- On Windows lock screen
- At the Windows 10 lock screen, if a security key icon is shown, select another sign-in option (such as PIN, password, or Windows Hello) from the sign-in options icons.
- After signing in, Windows will continue to offer the last-used method by default, so using PIN/Hello instead of security key will make those the primary options.
If a security key is not wanted at all, removing it from the Microsoft account and always choosing another sign-in method will stop the repeated “insert your security key” prompts.
