Connecting an ISP in MULogin

Why ISP proxy: you get the same IP every time you run. This is ideal for long sessions: accounts, billing, payments, careful account management without IP “chatter”.

Setting up “Fingerprints” (to Reduce Blockages)

Make the profile as similar as possible to a regular user’s computer:

  • WebRTC: turn it off so as not to “expose” the real IP.
  • Time zone: set it automatically by IP to avoid inconsistencies.
  • Geolocation: synchronize with the IP address.
  • System language: select the language that corresponds to the IP country/city.
  • Application/browser language: the same as the language by IP.
  • Screen resolution: use typical presets — this looks more natural.
  • Fonts: leave the standard sets to avoid standing out.
  • Hardware “noise”: enable all simulation options — this brings the behavior closer to a real device.
  • WebGL (metadata): specify common manufacturer/renderer values (for example, “Google Inc.”, “Apple”).
  • WebGPU: configure according to WebGL parameters

In the end, with these settings, your profile will look like a separate user – with its unique IP, device, language, and behavior pattern.
