Passwordless authenticationfor businesses
Remove the password as the weak point. Block-Auth handles login with cryptographic signature (wallet sign-in), social login, passkeys and TOTP: two factors in a single request and nothing reusable to steal or phish. It’s built on decentralized identity.
The password is the breach that never closes
The vast majority of breaches start with a stolen or reused credential. As long as a password exists, there’s something to phish, leak and sell. Passwordless takes that target off the table.
