You can connect Metabase to your JWT-based identity provider to allow your Metabase users to authenticate through it.
First, navigate to the Settings section of the Admin area, then click on the Authentication tab. Click the Configure button in the JWT section of this page, and you’ll see this form:
Click the toggle at the top of the form to enable JWT-based authentication, then fill in the form with the information about your identity provider. Make sure to turn this on, otherwise JWT authentication won’t work, even if all of your settings are right.
Here’s a breakdown of each of the settings:
Identity Provider URI: This is where Metabase will redirect login requests. That is, it’s where your users go to log in through your identify provider.
String Used by the JWT Signing Key: This is a string used to seed the private key that is used to validate JWT messages.
These are additional settings you can fill in to pass user attributes to Metabase.
Email attribute: the key to retrieve each JWT user’s email address.
First Name attribute: the key to retrieve each JWT user’s first name.
Last Name attribute: if you guessed that this is the key to retrieve each JWT user’s last name, well then you have been paying attention.
You can use your JWT to assign Metabase users to custom groups by following these steps:
Once you have configured your JWT authentication, you can choose to disable the option for users to log in via username and password. To do this, return to the main Authentication settings page and scroll to the bottom. A toggle will now be visible allowing you to make this change.
You can find example code that uses JWT authentication in the SSO examples repository.
Data sandboxes automatically filter specific tables for your users based on who they are. We’ll show you how to set these up next.
