To verify your Microsoft account without a phone, follow these options:
Use an alternate email: If you have a secondary email linked to your account, request the verification code be sent there.
Security questions: If you set up security questions when creating your account, answer them to verify your identity.
Authenticator app on another device: If you’ve set up the Microsoft Authenticator app on another device (like a tablet or computer), use it for verification.
Account recovery: Visit Microsoft’s account recovery page to reset your account and verify your identity using other available methods.
