Hi luckylumine,
Thank you for posting in the Q&A Forums.
I. Confirm the cause of the problem
Phone number not updated: Your 2FA settings are still bound to the old phone number, which may be the main reason why you cannot receive the verification code.
Account lockout: Multiple failed login attempts may result in the account being temporarily locked to protect account security.
CAPTCHA sending restrictions: Some systems limit the frequency of CAPTCHA sending to prevent abuse.
II. Solutions
- Use alternate verification methods
Alternate mailbox: Check if you have set up an alternate mailbox on GitHub (or other related services). If so, you can receive verification codes or a link to reset your password through that mailbox.
Recovery Codes: If you saved Recovery Codes when you enabled 2FA, you can use them to bypass 2FA login.
- Contacting Your Service Provider
Customer Service: Visit GitHub's official website or Help Center to find customer service contact information (e.g. email, live chat, or phone support). Explain your situation to them and provide enough authentication information to prove that you are the real owner of the account.
Account Recovery Process: Follow your service provider's instructions to complete the account recovery process. This usually includes steps such as answering security questions and providing identification documents.
- Check your network and device
Network Connection: Make sure your device is connected to a stable network and check for any network issues that may be preventing you from receiving CAPTCHAs.
SMS blocking: Check if your device has any apps or security software installed that may be blocking SMS messages and turn them off or adjust the settings to allow CAPTCHA SMS messages to go through.
- Try other login methods
Third-party authentication apps: If you are using a third-party authentication app (such as Google Authenticator or Microsoft Authenticator) instead of SMS CAPTCHA, make sure that the app is properly installed and set up as your 2FA method.
Change device: Try logging into your account using a different device to rule out device issues causing login failures.
