To sign into Gmail without phone verification, there are a few methods you can try, especially if you’ve lost access to your phone or simply prefer not to use it for verification. Here are some steps:

1. Use Backup Email: If you've previously set up a recovery email address, Gmail may give you the option to receive a verification link at that email. Check your inbox and follow the link to log in.

2. Answer Security Questions: If you set up security questions during account creation, Gmail might prompt you to answer them. Providing the correct answers may allow you to bypass phone verification.

3. Trusted Device Login: If you’ve previously logged into your Gmail account on a trusted device (like your computer or tablet), try accessing Gmail from that same device. Gmail may recognize it and allow you to log in without phone verification.

4. Authenticator App: If you use an authentication app like Google Authenticator, you can generate a code from there instead of relying on SMS-based phone verification.

5. Contact Google Support: If none of the above methods work, contacting Google support might be necessary to recover your account.

Ensure that your security settings are updated to prevent future lockouts. Google Account Recovery
