Undetectable takes the proxy as a single line. In New Profile open the proxy settings icon, choose New Proxy, pick the protocol on the left and type Host:Port:Login:Password into the field. The double-arrow button checks the exit IP, country and city before you save the profile.
Profiles → + New Profile → proxy settings icon → Proxy: New Proxy
The proxy field is the paste box: Host:Port:Login:Password in one line.
Open Undetectable, choose Profiles in the left menu and click + New Profile. Enter a profile name (1), then click the proxy settings icon in the middle of the toolbar (2).

Under Proxy select New Proxy (3). Set the protocol on the left to http for the HTTP port or socks5 for the SOCKS5 port, then type Host:Port:Login:Password in the field next to it (4). IP Change Link and the proxy name are optional.

Click the double-arrow button at the right of the proxy field. The exit IP, country and city appear below it. Click Create, then Open.

The double-arrow button next to the proxy field. The exit IP, country and city appear under it.
Create and open the profile. The proxy is stored with the profile; the Proxy page lists every saved line.
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.
Host:Port:Login:Password on one line, with the protocol chosen in the selector on the left. That is the host:port:user:pass line the dashboard generator exports.
Both. http with the HTTP port, socks5 with the SOCKS5 port, same host and login.
No. It is for rotation links; our sticky usernames keep or change the IP without it.
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.
