Authentication Method Configuration#
The Janssen Server allows administrators to set and manage the default authentication method for the authentication server. The Janssen Server provides multiple configuration tools to perform these tasks.
Note
Only one of the available authentication methods can be set as the default. While setting the Default authentication method, the Janssen Server checks if the same authentication is available and active.
See script documentation to know how to enable/disable authentication methods using custom scripts.
If the script is not active then the following error notification is
returned by API.
{
"code": "400",
"message": "INVALID_ACR",
"description": "Authentication script {acr} is not active"
}
Also, to understand how Janssen Server picks the authentication method in the absence of the default authentication method, refer to ACR documentation

Using Command Line#
Operations to manage the default authentication method are grouped under the
DefaultAuthenticationMethod task. To get information about those operations
use the command below.
jans cli --info DefaultAuthenticationMethod
Operation ID: get-acrs
Description: Gets default authentication method.
Operation ID: put-acrs
Description: Updates default authentication method.
Schema: AuthenticationMethod
To get sample schema type jans cli --schema <schma>, for example jans cli --schema /components/schemas/AuthenticationMethod
Find Current Authentication Method#
To get the current default authentication method use the command below.
jans cli --operation-id get-acrs
{
"defaultAcr": "simple_password_auth"
}
Update Default Authentication Method#
Let's update the Default Authentication Method using the Janssen CLI command line. To perform the put-acrs operation, we have to use its schema. To get its schema:
jans cli --schema AuthenticationMethod > /tmp/patch-default-auth.json
For your information, you can obtain the format of the AuthenticationMethod
schema by running the aforementioned command without a file.
defaultAcr string
AuthenticationMethod schema example.
jans cli --schema-sample AuthenticationMethod
{
"defaultAcr": "string"
}
We need to modify the patch-default-auth.json file.
We have seen that our default authentication method is simple_password_auth.
We are going to update it with passport_saml authentication method.
{
"defaultAcr": "passport_saml"
}
Now let's trigger the operation using the above file.
jans cli --operation-id put-acrs --data /tmp/patch-default-auth.json
It will show the updated result.
{
"defaultAcr": "passport_saml"
}
Using Text-based UI#
In Janssen, You can manage the default authentication method using the Text-Based UI also.
You can start TUI using the command below:
jans tui
Find Current Default Authentication Method#
Navigate to Auth Server -> Authn to open the Authn screen as shown
in the image below. In Default ACR sub-tab, available authentication
methods are listed
as radio buttons.
