MODERATORS
It's up to every individual website to use whatever specific type of hash function they want, so absent of really technical users that know how to change the cipher, they all just default to SHA-1 for maximum compatibility.
And some TOTP apps don't interpret the
algorithmparameter correctly, which makes it safer to go with the default SHA-1.Lemmy in fact was using SHA-256 for its earlier TOTP implementation and reverted back to SHA-1 since some people locked themselves out due to poor support in some TOTP app (among other issues, another was that the activation workflow never asked you to confirm the code you enrolled was working and generating the correct code...).
damn it.
