A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
Microsoft may temporarily block specific verification methods (like SMS or app codes) if there is unusual activity, too many repeated requests, or heavy suspicious traffic from a region. This can cause messages such as “this verification method is not working” or “try another verification method,” even when the account details are correct.
To get back in:
- Try a different verification method
- If SMS is failing, use any alternate email or other method already configured on the account to receive the code.
- If the Authenticator app is blocked, use SMS or email instead, if available.
- Try a different network
- Switch between Wi‑Fi and mobile data, or try a different Wi‑Fi network. Network changes can help if the block is tied to a specific IP or region.
- Wait before retrying
- Avoid repeated sign‑in or code requests; too many attempts can extend or reset the temporary block.
- Wait at least 24 hours before trying again. If it still fails, wait longer (up to about a week) before making many new attempts.
- Use the sign‑in helper
- Run the sign‑in troubleshooter to identify the issue and see available recovery/support options: use the Sign-in helper link in the guidance below.
- If still blocked
- If no verification method works and codes never arrive, support agents cannot send codes or change security details for security reasons. In that case, follow the sign‑in helper and support paths described in the article’s “Need more help?” section.
Note: VOIP numbers cannot be used for verification; only mobile numbers are supported.
