hi you can create a script which when started takes your ip and autheticates it i have made a python script i have to run once whenever my ip changes and its helpful (this as an alternative)

Please add Username & Password authentication as an option. Instead of IP authentication. As, my ISP provider keeps changing the ip. And, I need to authenticate every 3 to 4 days.

Yeah would be great too but add Captcha or Cloudflare as protection as many will try to deface your website - run something like Openbullet and shit
