I have a suite of services exposed using a reverse proxy (npm) protected with passwords, but I’m always a bit nervous that username/passwords aren’t enough – is there a way to set up 2FA either on Nginx Proxy Manager side or on, e.g., the 'arr suite of apps?
I usually recommend this one. There’s a section for NPM you’ll find useful.
Yeah, I think Ibracorp is great, found it useful in some detail questions Let me however recommend this link from Smart Home Beginner: I set up my server based on this one, with Authelia and Duo for 2FA
