Frictionless Wallets, Part 3: Biometric Login with Passkeys
3 min read
This is the final part of the series on making on-chain wallets feel like normal apps. Part one delegated non-financial signing to a device key-pair; part two replaced the seed phrase with a social login backed by a 2-of-3 secret. Part three removes the last piece of friction: unlocking the wallet with the device's biometric authenticator - Touch ID, Face ID, or a platform passkey - no seed phrase, no browser extension.
As with the rest of the series, this serves the Cardano ecosystem first and works across the chains EffectStream supports.
