External Identity Providers

When using an external identity provider, such as Auth0, they require a list of “Allowed Callback URLs”.

Does this need to be the URL to my Ignition instance?

Most likely, yes. See: OpenID Connect 1.0 Example - Ignition User Manual 8.0 - Ignition Documentation

Specifically: steps 8 and 9

I am attempting to test this with Ignition running on my laptop. I don’t really have an IP address to get to my machine at the moment (don’t have that type access to the router).

I will have servers up next week that will have dedicated IP address and domain name so maybe I wait until then to get this completely setup.

Most IdPs support callback URLs with localhost / You could try that.
