You cannot install a barebones TOTP app on your Nokia 3310 because it is closed source.
Most services don't offer third party TOTP because they are pressured into pushing their shitty proprietary apps.
But TOTP not only is more secure but it's completely offline. It's close to the best solution and totally exists right now
Most of the new alternatives seem focused on pushing lock-in traps and are complicated for users to understand or use. If they're going to lose user tracking of the phone number they want something even worse to replace it, not something open like TOTP.
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?
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?
There are of course examples of vendors that don't. I think Steam is one of them. And my bank.
