Incogniton keeps the proxy on the Proxy tab of every profile. Select Custom proxy, pick the Connection type, type the gateway host and port as ip:port in the Proxy field, then the username and password. The Check button verifies the exit IP; Create saves the profile.
Profiles → Create profile → Proxy tab → Custom proxy
The Proxy (ip:port) field also accepts a pasted url:port:username:password line.
Open Incogniton, choose Profiles in the left menu and click Create profile. Fill the Details tab as you like, then open the Proxy tab.

Select Custom proxy. Set Connection type to HTTP for the HTTP port or SOCKS5 for the SOCKS5 port (HTTPS here is a TLS proxy and does not apply). In Proxy (ip:port) type the gateway host, a colon and the port; then fill Proxy username and Proxy password. Leave Rotating proxy off.

Click Check under the fields. Connected, with the exit IP, country and time zone, means the line works. Then click Create in the lower-right corner.

Check, under the proxy fields. Connected plus the exit IP and country confirms the line.
Launch the profile from the Profiles list. The rest of the profile (Privacy & Network, Hardware, Extensions & Cookies) can be set before or after the proxy.
Copy the line from the dashboard (Proxies, your plan, the proxy generator) rather than typing it: it already carries the country, the session id and the session length in the username. The table shows what each field holds.
| Plan | Host | HTTP port | SOCKS5 port | Username shape |
|---|---|---|---|---|
| Residential Premium | residentialpremium.quantumproxies.io | 8080 | 1080 | USER-country-us-sid-k3f9a1b2-ttl-60m |
| Residential Basic | residentialboson.quantumproxies.io | 9000 | from the generator | USER-country-us |
| Mobile | mobile-us.quantumproxies.io (also -eu, -as, ww) | 8080 | 1080 | USER-country-us-type-mobile |
| Datacenter (per GB) | datacenterboson.quantumproxies.io | 9999 | 10000 | USER-type-datacenter-country-de |
| IPv6 | ipv6.quantumproxies.io | 1001 | from the generator | USER-country-us-package-ipv6 |
| ISP (dedicated IP) | the IP of your line | 8000 | on the plan page | the line's own login |
The password is the one the generator prints next to the username. Pick HTTP or SOCKS5 in the tool and use the port of that column; a port from the other column is the most common reason a check fails. USER and the session id are placeholders for your own values.
HTTP, with the HTTP port of your plan. HTTPS in Incogniton means a proxy that speaks TLS on the proxy port, which our gateways do not. SOCKS5 works with the SOCKS5 port.
In the same field as the host: Proxy (ip:port) takes host:port. The username and password have their own fields below.
Yes, Proxy Library lets you save a line and assign it to profiles. Keep one sticky line per profile anyway: two profiles on the same session id share one IP.
Skip the marketing. QuantumProxies.io publishes a machine-readable site map, Markdown for every page, a free MCP server, and APIs billed from the same balance as your proxies.
