Tell HN: Moving Away from GitHub (2FA)

I have forty-something days to enable 2FA on my GitHub account. Nothing against 2FA in general, but GitHub requires me to either provide my phone number (for sms), or install apps (GitHub app or one to get 2fa codes). Passkeys are available but only if I have already 2fa via sms/codes.

Why can’t I just provide a second email as 2FA? That would be so easy to implement. I move around frequently and I don’t really have a permanent phone number (besides I don’t really take my phone with me that much) and I don’t want to rely on yet another app on my phone to login to things.

I use GitHub as a free place to have backups of code I don’t mind being public. So, 2FA is not really something I need (I understand it’s a must for other types of users).
