We proudly present the TotpAuthenticator. One step closer to zero trust and one step away from web2. You can now use 2FA authentication for your business contacts your web-applications or even your IOTs without a centralized database storing your keys and authenticating users. The Blocqchain takes over!

Hashing

How to calculate and submit hash:

convert TOTP (eg. 123456) to bytes/hex with ethers. Padding left!!! Then sha256 it and insert 0x at the start. That's it, now it should match the sha256 on-chain.
