Expressions are used in different places throughout authentik, and can do different things.

|
|||
|
||||
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.

Currently, only Duo push notifications are supported. Because no additional input is required, Duo also works with the LDAP Outpost.

|
||||
- Multi-tenancy
|
||||
|
||||
This version adds soft multi-tenancy. This means you can configure different branding settings and different default flows per domain.
|
||||
|
||||
This also changes how a default flow is determined. Previously, for defaults flow, authentik would pick the first flow that
|
||||
|
||||
- matches the required designation
|
||||
- comes first sorted by slug
|
||||
- is allowed by policies
|
||||
|
||||
Now, authentik first checks if the current tenant has a default flow configured for the selected designation. If not, it behaves the same as before, meaning that if you want to select a default flow based on policy, you can just leave the tenant default empty.
|
||||
|
||||
## Minor changes
|
||||
|
||||
- You can now specify which sources should be shown on an Identification stage.
