About account authentication

After I sign up for an account on GitHub, I can’t log in. I tried to log in with the email address I bound to GitHub, but found that authentication was required.
At first I didn’t want to authenticate, but if I did, I wouldn’t even be able to log in for the first time. So I decided to authenticate. Finally, the verification results tell me that the age does not match.
Region: China. Age: 13 years
Is there any limit to this? I just wanted to practice the networking techniques I learned.

Hi :wave:t6: thank you for writing in. At this time the only solution for signups is verification or upgrading to a pro tier or higher account.
