Profiles → Browser list → Proxy column edit icon → Modify Proxy → New proxy
Open MoreLogin, choose Profiles in the left menu and stay on the Browser list. Create a profile with New profile if you have none, then click the edit icon in its Proxy column.

In the Modify Proxy window select New proxy. The Proxy type, IP query channel, Proxy server, Proxy account and Proxy password fields appear.

Set Proxy type to HTTP or SOCKS5 to match the port. Type the gateway host in Proxy server and the port in the box after the colon, then the username in Proxy account and the password in Proxy password. Refresh URL stays empty.

Click proxy detection at the bottom. Check passed with the exit IP and location means the line works; click Confirm.

The profile list now shows the proxy in the Proxy column. Click Start on the row to open the browser.

proxy detection, at the bottom of Modify Proxy. Check passed shows the exit IP and location.
Start the profile from the list. To change the IP later, generate a line with a new session id and edit the proxy again.
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.
In the Proxy server field after the colon: the host goes first, the port in the small box on the right of the same row.
Both are listed under Proxy type. Use the HTTP port with HTTP and the SOCKS5 port with SOCKS5.
The Purchase proxy tab sells other providers' lines. A QuantumProxies line goes through New proxy with the values from your dashboard.
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.
