I lost 2FA access to my old GitHub account, and there was no way to recover it.

After talking with GitHub support, they said I could only get my old username back.

I have to import my old repositories manually to this new account for the rest.

Private repositories also got lost. There were many projects.

I have manually imported old repositories into this account now. My old account can be accessed from here: - https://github.com/himanshuchandola-zz
