Sign-in
Passkeys that really verify.
Passkeys let your users sign in with their face, fingerprint or device PIN. Synq checks every step itself, and a passkey made for one brand never works at another.
Offered as people type
A “Use a passkey” button, and the email field offers saved passkeys as the person types. New users can sign up with a passkey alone.
User verification, always
Every ceremony requires user verification, and the signature counter must go up, so a cloned device-bound passkey is refused and recorded.
One brand each
The relying party is the brand’s own issuer, so passkeys never cross from one of your brands to another.
Managed from your app or ours
People add and remove passkeys through the account API, and your team sees and removes them through the management API. Adding one emails the person.
