GitHub will disable non-2FA accounts?
otpauth:// is a de-factor standard, since Google Authenticator uses it: https://github.com/google/google-authenticator/wiki/Key-Uri-...

Creating 2fa with pyotp
Random question if you're using TOTP why not just give the user the secret when signing up as a Google Authenticator URI encoded in a QR code? Then you won't need to futz around with sending it to them afterwards. You can even use a library like qrcode.js so you don't generate the barcode server side either.
- why are all the totp secrets different styles?

Does changing an email that has TOTP setup affect the "secret"?
(Examples> https://github.com/google/google-authenticator/wiki/Key-Uri-Format)
- Google Authenticator open source fork archived
- TOTP tokens on my wrist with the smartest dumb watch
- LastPass gehackt, Nutzerdaten aber anscheinend sicher
- Is google authenticator Private & Secure (Trustworthy) enough to be used for 2StepVerification?

Twilio, the people who own Authy, got hacked
If we're talking about the encrypted Authy TOTP secrets and IF they get cracked or guessed, Authy does store the email in the name of the item. Having the name, service and the secret within the QR code's URI is normal and the standard for TOTP. The only thing the hackers won't have is the password.
