Flows

Flows are a method of describing a sequence of stages. A stage represents a single verification or logic step. They are used to authenticate users, enroll them, and more.

Upon Flow execution, a plan is generated, which contains all stages. This means upon execution, all attached policies are evaluated. This behaviour can be altered by enabling the Re-evaluate Policies option on the binding.

To determine which flow is linked, passbook searches all Flows with the required designation and chooses the first instance the current user has access to.

Permissions

Flows can have policies assigned to them, which determines if the current user is allowed to see and use this flow.

Designation

Flows are designated for a single Purpose. This designation changes when a Flow is used. The following designations are available:

Authentication

This is designates a flow to be used for authentication.

The authentication flow should always contain a User Login stage, which attaches the staged user to the current session.

Invalidation

This designates a flow to be used for the invalidation of a session.

This stage should always contain a User Logout stage, which resets the current session.

Enrollment

This designates a flow for enrollment. This flow can contain any amount of Prompt stages, E-Mail verification or Captchas. At the end to create the user, you can use the User Write stage, which either updates the currently staged user, or if none exists, creates a new one.

Unenrollment

This designates a flow for unenrollment. This flow can contain any amount of verification, like E-Mail or Captcha. To finally delete the account, use the User Delete stage.

Recovery

This designates a flow for recovery. This flow normally contains an Identification stage to find the user. Then it can contain any amount of verification, like E-Mail or Captcha. Afterwards, use the Prompt stage to ask the user for a new password and use User Write to update the password.

Change Password

This designates a flow for password changing. This flow can contain any amount of verification, like E-Mail or Captcha. Afterwards, use the Prompt stage to ask the user for a new password and use User Write to update the password.
