Well I have a smartphone but I still don't want a shitty app for each service.

What's all this about SMS being insecure? I never heard of phone numbers being hijacked in my country (except in the case of physically stolen phones ofc). Is this another consequence of US making it so easy to steal an identity?

TOTP does not require one app for each service, plus phone scams and sim cloning is rampant. Seems you have limited experience un both subjects

> TOTP does not require one app for each service

That is, if your vendors all agree on something.

> Seems you have limited experience un both subjects

Yes, also limited experience on identity theft. Care to comment on my suspicion?

TOTP is a standard; if your vendor supports it, that _is_ them agreeing on something.

I have a bunch of vendors (e.g. Microsoft, Google, Gitlab, VPN, others) in the same OTP app in my phone, so my belief is that they seem to agree just fine.

There are of course examples of vendors that don't. I think Steam is one of them. And my bank.
