It will soon. I think I have to sort it out before April 4. My passwords are already >20 random characters, so I wasn't going to do it until they told me to.
If you are using pass to store those, check out pass-otp and browserpass, since GitHub still allows TOTP for MFA. pass-otp is based on oathtool, so you can do it more manually too if you don't use pass.
