今天在renew我的github学生包的时候提醒必须要开2FA验证，Github推荐了几个软件，但是问题来了，这些软件都是要付费的，万一停止付费我还能登录我的GitHub账号吗？

Setup authenticator app

Authenticator apps and browser extensions like 1Password, Authy, Microsoft Authenticator, etc. generate one-time passwords that are used as a second factor to verify your identity when prompted during sign-in.

Download your recovery codes

You can use recovery codes as a second factor to authenticate in case you lose access to your device. We recommend saving them with a secure password manager such as 1Password, Authy, or Keeper.
