What's happening
Two-factor codes are only sent when someone is trying to sign in or authorise something. If one arrives and it wasn't you, the likely explanation is that someone else has entered your password and is being stopped at the second step — which is exactly 2FA doing its job.
What to do
Never read the code to anyone, and never approve a prompt you didn't start. Change your password to a new, unique one right away, review your sessions, and report it via reporting suspected fraud. This is a good moment to add a passkey too.
