This is my issue with authy(the 2fa provider that twitch and others use). TOTP needs 2 things to function, a shared secret and a synced clock. No phone number.

This is my issue with authy(the 2fa provider that twitch and others use). TOTP needs 2 things to function, a shared secret and a synced clock. No phone number. No email. No account. No personal information. All you need is a secure connection to send a 16-32 bytes of data and to both have synced with an NTP server recently, yet there's no way to get the shared secret from authy without giving out personal information.
