Handle web biometrics
The ForgeRock JavaScript SDK has the following methods for handling web biometrics:
FRWebAuthn.register(step, deviceName)-
For registering new devices. Optionally, assign a name to the device to help the user identify it.
FRWebAuthn.authenticate(step)-
For authenticating using a previously registered device.
Use the FRWebAuthn.getWebAuthnStepType() convenience method to determine which method to use:
// Determine if a step is a web biometrics step
const stepType = FRWebAuthn.getWebAuthnStepType(step);
if (stepType === WebAuthnStepType.Registration) {
// Registering a new device, with optional device name
step = await FRWebAuthn.register(step, 'myDeviceName');
} else if (stepType === WebAuthnStepType.Authentication) {
// Authenticating with a registered device
step = await FRWebAuthn.authenticate(step);
}
// `step` has now been populated with the web biometrics credentials
// Send this new step to the ForgeRock server
nextStep = FRAuth.next(step);
