Microsoft sends texts like "Use 1234 as Microsoft account security code" when you sign in or change settings. It is real if you asked; never share it.
A real security code text gives only the code. A message asking you to call a number, tap a link to "keep your account", or pay anything is a scam. Microsoft does not phone people to ask for codes.
Choose another method on the sign-in screen, such as email or an authenticator, or read when Microsoft does not send the code.
Work and school accounts are managed by your organisation, not by you. If a code for a work account does not arrive, or you changed phones, contact your IT team: they can reset your sign-in methods. Personal account steps, such as the recovery form, do not apply to work accounts.
Yes, if you just tried to sign in or change settings. Otherwise ignore it and check your account.
Someone may be trying your email address. Check sign-in activity and use a strong password.
Use an authenticator app or passkey instead, then remove or keep the phone only as a backup.
