For anything? Why not? Surely you don't believe SMS-based TOTP is safer, right?
Wut. TOTP doesn't involve sending an OTP. That's the point.
"SMS-based TOTP" is a nonsensical phrase
"Time-based One-Time Password" literally says nothing about the delivery method. Who said it can't involve remote sending?
And what would you call it, then, SOTP?
Anyway, regardless of the terminology-nitpicking, my point still stands.
The point of being time based is to not send it. That's the whole point. To avoid that vecotor of attack.
Do you think the SMS codes are not time-based on the companies' ends? How are they deriving the digits, then?
They are not time based, correct.
Interesting, I didn't know that. So how do they derive the digits?
Best practice for a cryptographic nonce is to generate them randomly every time
