What is test mode?
Test mode is an environment that allows developers to try out the Clef integration before pushing it to their live website. In test mode, when the Clef wave is displayed, an alert is shown so the user knows they are logging in to an application that is not yet production ready.
If you are a developer working on an integration and are trying to go live, make sure that the Clef button is configured with the correct application ID. Test and production instances have different credentials, which you can access through your dashboard.
If you are a user, you should not proceed with logging in since this application is not yet ready to handle live users.
