Hive Authentication is quite innovative as it combines cryptographic signing, censorship resistant blockchain technology, the ability to reset the keys without reseting your identity, and the account recovery process. Hive is an excellent choice for decentralized online identity management.
SIM cards are not much inferior to TOTP apps on vulnerable smartphones imo. Both can be jacked but you need social engineering, inside job, or physical access to jack a cold SIM card.
Metamask and all EVM are quite impractical when you need to reset your keys. I don't understand how soulbound tokens could work in the real world using EVM based infrastructure.
