How do I access the picture entity with a url?

Configuration
1

hi all, externally to HA I can access the picture entity with the URL from the states area like this:

/api/camera_proxy/camera.combined?token=a5aa3747e8c0cc4e6

but the token isn’t permanent

previously I have used

/api/camera_proxy/camera.combined?api_password=tech

but that has changed to the auth_providers: section and no longer works
