I am an international student and I literally hate when they don't let me put in 2 different numbers. I get locked out when I travel. For example, twitter

There is a setting for a fallback number on https://github.com/settings/two_factor_authentication/config...

Use Google Voice or some other similar service that'll let you receive SMS via the web.

Wow thanks for that. I have Google voice account for forever and never thought about this.

Edit: This also connects every other account to my Google account, so I should only worry the Google account.

Bear in mind that if one login and password lets you get to both the password reset email and your SMS 2nd factor, you've turned two factor auth back into one factor auth. (So, then, turn two factor auth on your Google account...)

You are definitely right, but even though other accounts 2nd factor auth can be passed via password reset email, that would require a login to my gmail, but my Google account also has a two factor auth.

Edit: sorry for repeating you, I just show your footnote parentesis

Be careful with that. A lot of automated SMS systems can't send to Google Voice.

Yup. I was not aware that some phone numbers were more equal than others when it comes to SMS service.

Good to know!

Use an app, not the SMS service. Or get a spare phone to carry your "primary" SIM card in, receiving texts abroad are typically free.
