A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
The message indicates that the current verification method is blocked or unavailable, often due to unusual activity, too many attempts, or security policies. When this happens, the system requires a different verification method or time to clear the block.
Take these steps in order:
- Try a different verification method
- If the account has more than one method configured (alternate email, another phone number, Microsoft Authenticator, security key), choose a different one when prompted.
- The block may be tied only to SMS or to a specific number, so using an alternate email or another method can allow sign-in.
- Switch network and device
- Switch between Wi‑Fi and mobile data, or try a different Wi‑Fi network.
- If possible, try the sign-in or reset flow from another device (for example, a different phone or PC). This can help if the block is related to the current network or device.
- Stop repeated attempts and wait
- Multiple failed or repeated sign-in and verification attempts can trigger additional blocking.
- Wait at least 24 hours without trying again. Do not keep requesting codes or restarting the flow, as this can reset the time lock.
- If the block persists, wait longer (up to a week) before trying again.
- Use the sign-in helper
- Run the sign-in helper tool, which is designed to diagnose sign-in and verification issues and show available recovery options: use the Sign-in helper link provided in the documentation.
- If this is a work or school account with Microsoft Entra multifactor authentication
- Repeated attempts can cause Entra MFA to temporarily prevent additional sign-ins.
- Use a different MFA method if one is configured (for example, app notification instead of SMS).
- Contact the organization’s IT administrator or Help desk and ask them to:
- Check Microsoft Entra sign-in logs for blocked or suspicious attempts.
- Reset or reconfigure MFA methods if necessary.
- If still unable to receive any codes
- If no verification method works and no codes are received, it may be necessary to wait until access to the registered phone or email is possible, or to add/update methods once sign-in is restored.
- Support agents cannot send verification codes, password reset links, or change security details on the account for security reasons.
- For additional technical help, go to Contact Microsoft Support from the documentation and select Get Help, then Contact Support if more assistance is needed.
If the password itself is the issue (forgotten or stopped working), follow the documented flows for resetting a forgotten password or using the Sign-in Helper tool to recover access, then update security info as soon as sign-in is restored to avoid being locked to a single method.
