@mpociot @freekmurze Can we have some attention on this issue? It's working fine and I've been testing it for the last few days without any issues. Would be great if it's merged.

We also need this! Very useful @irazasyed

will this allow to access the dashboard without a user at all? I mean, can I disable the authorize completely? This is what I do for Horizon/Telescope

I comment out the Authorize middleware completely and replace it by 'under-construction'

from https://github.com/larsjanssen6/underconstruction

This way I can protect my admin routes with a 4 digit pin and don't need to have a user system available at all on some of my apps

@vesper8 Yes, You can do that.
