Cloudflare should probably deprecate their Authy provider, considering they support other more secure MFA options (hardware and virtual WebAuthN). I believe Wise (ex TransferWise) and Plastiq also use Authy natively for SMS OTP server side, but provide no mechanism to disable SMS 2FA (boo).
Thank you for correcting me, Cloudflare was presented as an Authy token that would be destroyed when I deleted my Authy account and some of the docs I found led me to believe this was still actively in use. I retract the Cloudflare part of my above comment.
No need to apologize. We did use Authy for a long time but allowed more general TOTP solutions from 2017 and have really pushed hard for people to use hardware keys.
