title: Overview
|
|
---
|
|
|
|
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.
|
|
|
|
For example, a standard login flow would consist of the following stages:
|
|
|
|
- Identification, user identifies themselves via a username or email address
|
|
- Password, the user's password is checked against the hash in the database
|
|
- Log the user in
|
|
|
|
Upon flow execution, a plan containing all stages is generated. This means that all attached policies are evaluated upon execution. This behaviour can be altered by enabling the **Re-evaluate Policies** option on the binding.
|
|
|
|
To determine which flow is linked, authentik 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. These policies determine if the current user is allowed to see and use this flow.
|
|
|
|
Keep in mind that in certain circumstances, policies cannot match against users and groups as there is no authenticated user yet.
|
|
|
|
## 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**](stages/user_login.md) stage, which attaches the staged user to the current session.
|
|
|
|
### Invalidation
|
|
|
|
This designates a flow to be used to invalidate a session.
|
|
|
|
This stage should always contain a [**User Logout**](stages/user_logout.md) stage, which resets the current session.
|
|
|
|
### Enrollment
|
|
|
|
This designates a flow for enrollment. This flow can contain any amount of verification stages, such as [**email**](stages/email/) or [**captcha**](stages/captcha/). At the end, to create the user, you can use the [**user_write**](stages/user_write.md) 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 stages, such as [**email**](stages/email/) or [**captcha**](stages/captcha/). As a final stage, to delete the account, use the [**user_delete**](stages/user_delete.md) stage.
|
|
|
|
### Recovery
|
|
|
|
This designates a flow for recovery. This flow normally contains an [**identification**](stages/identification/) stage to find the user. It can also contain any amount of verification stages, such as [**email**](stages/email/) or [**captcha**](stages/captcha/).
|
|
Afterwards, use the [**prompt**](stages/prompt/) stage to ask the user for a new password and the [**user_write**](stages/user_write.md) stage to update the password.
|
|
|
|
### Stage configuration
|
|
|
|
This designates a flow for general setup. This designation doesn't have any constraints in what you can do. For example, by default this designation is used to configure Factors, like change a password and setup TOTP.
