I have no education i learned all through trial an error an google

I personally use a vps for this stuff but my setup is standalone nginx as a reverse proxy and fail2ban and ufw

It was a pretty huge learning curve but it was great learning to troubleshoot stuff i also set up oauth2-proxy and that was also a bit of learning curve but worth it in the end

I set up oauth for my sites

I did try it out and its great! One issue i had is after logging in it says not found however

Voidauth looks intresting. Thanks!

for the custom API i run navidrone i use aonsoku on my PC and it supports custom URL.
