A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
The calls and voicemail are consistent with Microsoft’s automated sign-in or verification system trying to complete a sign-in or security check on an account that has your phone number configured for verification.
Key points and actions:
- Why this is happening
- Microsoft may send calls or texts when someone (possibly not you) tries to sign in or use a feature that requires identity verification on an account that has your phone number set as a security method.
- If a verification code or sign-in attempt is triggered but not completed correctly, messages like “we didn’t receive a response” or “we can’t sign you in at this time” can be generated.
- If you did not initiate any sign-in, it can mean either:
- Someone mistyped their phone/email and used your number by accident, or
- Someone is trying to access an account that uses your number.
- What to do immediately
- Do not respond to the call, press keys, or provide any information in response to the voicemail.
- Do not click on any links from texts related to these calls.
- Instead, go directly to the Microsoft account site by typing
https://account.microsoft.comorhttps://account.live.cominto a browser (not via links in messages) and review:- Recent activity
- Security alerts
- Security info (phone numbers and email addresses on the account)
- If the account is yours
- Confirm that the phone number listed in your security info is correct.
- If there are sign-in attempts you do not recognize, follow the guidance to help keep the account secure and update security settings as needed (change password, review devices, etc.).
- If the account is not yours or the number is misused
- If the number was added to someone else’s Microsoft account by mistake, the owner of that account must remove or change it in their security info.
- If the calls persist and you are sure you do not use this number with any Microsoft account, consider blocking the number on the phone and contacting the mobile provider for additional options.
- General safety guidance
- Microsoft will not proactively call to offer unsolicited technical support.
- If unsure whether a message or call is genuine, always sign in directly via
https://account.microsoft.cominstead of using any link or callback number from the message.
