Knit
Passwordless sign-in for every app
An identity server that gives your apps passwordless sign-in with passkeys, social login, and QR-code sign-in on any device — one account your users take to every app.
What Knit is
Knit is an identity server for businesses whose apps need secure, passwordless authentication. Your users sign up and sign in with passkeys — fingerprint, face scan, or device PIN — social accounts they already have, or by scanning a QR code on another device. No passwords to remember, no OTPs to type.
Why it’s different
Most identity solutions either lock you into a specific ecosystem or still rely on passwords. Knit puts passkeys first — the most secure and convenient sign-in method — while supporting social login and QR-code sign-in as seamless alternatives. Users can connect a social account or add a passkey on a second device, so losing a phone doesn’t mean losing the account.
Highlights
- Passkey sign-in. Users sign up and authenticate with their device’s built-in biometrics or PIN — fingerprint, face scan, or screen lock. Works on any modern phone, tablet, or laptop. No passwords to manage.
- Social login. Let users sign in with Google, Microsoft, Apple, Facebook, X, or Telegram. They use what they already have; you get verified identities.
- QR-code sign-in. Perfect for shared computers, kiosks, or TV screens. Users scan a QR code with their phone — no typing, no credentials on the shared device. New devices are approved from a phone the user already trusts, with full or login-only access.
- Backup sign-in. Users keep a connected social account or a passkey on a second device, so a lost phone doesn’t lock them out. Knit warns them while they have no backup.
- App directory. Users see every app they can access in one place and open any of them with a single click.
- OpenID Connect provider. Any app that supports OIDC can use Knit as its identity provider — internal tools, partner portals, or customer-facing apps.
