Email or Authenticator option in lieu of OTP mobile alerts

I know many don’t like to give out their mobile phone numbers except to trusted sources. ChatGPT, in my opinion, isn’t a trusted source. Financial institutions and government agencies are, though.

I’d like to see other verification methods aside from mobile number verification. VOIP doesn’t work either.

I know some other unhinged apps like Telegram also insist on an actual mobile number. I know some may not mind because they play musical chairs with their carriers and switch often, so they don’t have any value or care in giving up their mobile number. It’s basically a disposable number for them anyway
