VMLogin opens the proxy in its own window from Basic configuration. Click Setting proxy server, switch on Enable proxy server, choose the Proxy type, then type the gateway host in IP address and the port in Port, with the login in Username and Password. Test Proxy shows the exit IP and city.
New browser profile → Basic configuration → Setting proxy server → Enable proxy server
Paste proxy info reads a host:port:user:pass line into the four fields.
Open VMLogin and click New browser profile on the left. Give the profile a display name.

Under Basic configuration click Setting proxy server. The Proxy settings window opens; switch on Enable proxy server.

Set Proxy type to HTTP Proxy for the HTTP port or SOCKS5 Proxy for the SOCKS5 port. Type the gateway host in IP address, the port in Port, the username in Username and the password in Password. Or click Paste proxy info with the full line on the clipboard and check the fields.

Pick a site under Test IP URL and click Test Proxy. The result shows the exit IP with country, city, region and time zone. Click Save, then save the profile.

Test Proxy, next to Test IP URL. The result lists the exit IP, country, city and time zone.
Save the proxy window and the profile, then launch it from the profile list.
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.
It reads a host:port:user:pass line from the clipboard into IP address, Port, Username and Password. Check the Proxy type afterwards: it is not part of the line.
Either. HTTP Proxy with the HTTP port of your plan, SOCKS5 Proxy with the SOCKS5 port.
Any of the listed IP sites works; they only report the exit IP and location. The QuantumProxies IP checker gives the same answer from inside the profile.
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.
