Onboarding Options
Estimated time to read: 1 minute
Apps using Arcana Auth SDK can enable passkey login in two ways:
- Allow new users to sign up with passkeys, making it the only login option.
- Let existing users set up passkeys as an alternative login method, alongside other social login options.
Passkey Sign-up
To sign up with passkeys, use registerWithPasskey(), followed by loginWithPasskey() to sign up and log in in one step. The user must provide a unique identifier—this could be a name, email, device ID, biometric data, PIN, or pattern. This sign-up flow is ideal for apps that only allow passkey onboarding.

Passkey Login
To use passkeys as an alternative login, users first need to onboard through another method, like social login. Once logged in, they can set up a passkey for future logins. Use linkPasskey() to create and associate passkey with the app or website. Next time, when user chooses passkey option to log in, the app can call loginWithPasskey(), triggering the device or browser to display a UI where the user can choose the previously set passkey. This flow works best for apps that support multiple onboarding methods. See details...
