@watchoutfreedom ill proceed with this next.. since you requested it on the #4 ;)

I am having the tendency to use this type of authentication...
https://swagger.io/docs/specification/authentication/bearer-authentication/

but would be maybe way more interesting to think about something like
https://swagger.io/docs/specification/authentication/oauth2/

but since its more complex might delay to much other more important components.. so i would go on with the more simple, and later we see if we want to upgrade to something else.

what do you think?

[watchoutfreedom]

Yes let's make an issue with the more complex and make the simpler for now
