as I now have
- Traefik dashboard
- discourse
- Mattermost
on https, thus I'm almost done with my first stage.
The last action on Traefik is authentication of the dashboard and whoami.
It is explained in https://containo.us/blog/traefik-2-0-docker-101-fc2893944b9d. I can either use [BasicAuth]-(https://docs.traefik.io/v2.0/middlewares/basicauth/) or DigestAuth whereby BasicAuth should be enough according to https://stackoverflow.com/questions/9534602/what-is-the-difference-between-digest-and-basic-authentication.
What it does not tell me, is how the user/password prompt is happening.
Will be there a browser built-in pop-up asking me for user and password?
