Expert Opinion

Imagine receiving a robotic voice at 3 a.m. asking you to press the # key for a login. That’s a typical MicrosoftMFA call, used to confirm you’re the one trying to access an account. If you didn’t start a sign‑in, let the call go to voicemail and don’t press any keys – the system can’t verify you without your initiation. Keep an eye on your phone bill for unexpected charges and consider blocking the number if it becomes frequent. For added safety, enable the Microsoft Authenticator app, which eliminates reliance on phone calls. Report repeated unwanted calls to your carrier and to Microsoft’s support team.
