OAuth Two-Factor Authentication Workflow Diagram Text Description

The two-factor workflow for OAuth at the Registry is as follows:

1. The Registry invokes the SendTwoFactorToken callback in the security domain callback class. The security domain callback class is your custom class that extends HS.Registry.Person.User.HSAuth.

2. The callback delivers the two-factor token to the user.

3. The Registry displays the HealthShare two-factor user interface page.

4. The user enters the two-factor token on the page. If the user instead requests the token to be resent, then the SendTwoFactorToken callback is invoked again.

5. HealthShare validates the token.
