Which Android browser setups accept a proxy username and password, and how to test one in two minutes.
Google's Pixel help lists the path Settings, Network & internet, Internet, your network, edit, Advanced options, Proxy, then a configuration type and the proxy settings. It names no username or password field, and it says the steps vary by device.
Android's developer documentation adds that this system proxy is used by web browsers and most applications, but some apps may ignore it, and that it primarily handles only HTTP and HTTPS traffic. So a browser that follows the system proxy gets no login prompt from the setting itself, and traffic outside HTTP and HTTPS may not be covered.
| Item | Username and password | What it covers | Protocols |
|---|---|---|---|
| System Wi-Fi proxy | Not offered in Google's help | Browsers and most apps that read the system proxy; one Wi-Fi network at a time | HTTP and HTTPS mostly |
| Firefox for Android plus a proxy extension | Listed by the extension's developer, test it | Pages opened in that Firefox only | HTTP, HTTPS, SOCKS4, SOCKS5 as listed |
| VPN-mode client app (Postern) | Yes: address, port, username, password | Every browser and app on the phone while the VPN is on | HTTP or SOCKS5, chosen in the profile |
Sources: Google Pixel help and Android Developers (read 15 November 2026), the Proxy Manager listing on addons.mozilla.org (developer's claims, read 15 November 2026) and the Proxy302 Postern guide. No other browser was tested for this table.
Need one browser only, for example to check a page from another country? Firefox for Android with a proxy extension keeps the proxy out of your other apps. Need an app and a browser to use the same IP, or a proxy with SOCKS5? Use a client app in VPN mode.
A browser not in the table may also work, but this page names only setups whose own documentation or listing says what they do. Whatever you choose, test with a real login proxy before relying on it, because extension features and app behaviour change between versions.
Install the Proxy Manager add-on from addons.mozilla.org in Firefox for Android, or another proxy add-on whose listing says it supports login.
Add a proxy with the type, host, port, username and password from My assets. For Proxy302 the gateway is proxy.proxy302.com, port 2222 for HTTP and 3333 for SOCKS5.
Before continuing Use the protocol your IP was issued with.
Open https://ipinfo.io/json in Firefox. The IP and country shown should be the proxy's. If the page shows your own IP, the add-on is not active for that tab.
Check Is the proxy turned on in the extension, or the VPN on in the client app? Did you set the proxy on one Wi-Fi network and then switch to mobile data?
Fix Turn it on, or set it again on the network you are using. The system setting described by Google is per Wi-Fi network.
Stop when If it still shows your own IP after a restart of the browser, test the same login with curl on a computer.
Check Username and password copied exactly from My assets, with no trailing space; protocol matches the IP.
Fix Copy them again. If the IP was issued as HTTP, enter it as HTTP on port 2222.
Stop when If the same credentials fail on a computer too, open a ticket with the order number.
Check Host, port and type (HTTP 2222, SOCKS5 3333 on proxy.proxy302.com), and whether the phone has a VPN already on.
Fix Correct them and turn off other VPN apps, since Android runs one VPN at a time.
Stop when If the address and port are right and it still fails, send the order number to support.
Pick the IP. For an account you keep signed in, a static ISP IP costs US$0.50 for 1 day or US$7.99 for 30 days, the same in every country. For checks and scraping, rotating residential is billed per GB.
Open My assets and copy host, port, username and password. HTTP uses port 2222 and SOCKS5 port 3333 on proxy.proxy302.com.
Enter them in Postern or in your Firefox add-on, then confirm the exit with ipinfo.io before you log in anywhere.
Android's own proxy setting has no login fields in Google's help. Firefox for Android with a proxy extension that lists login support, or any browser used through a VPN-mode client app such as Postern, can use one. Test it with your proxy first.
Android's developer documentation says the system proxy is used by web browsers, and Google's help shows no username or password field for it. For a login proxy, use a client app in VPN mode.
The system proxy primarily handles HTTP and HTTPS. For SOCKS5 use a client app such as Postern, or an extension that lists SOCKS5 support.
Open https://ipinfo.io/json in the browser. It should show the proxy's IP and country, not yours.
No. The smallest purchase is one static ISP IP for one day at US$0.50.
How to set a system proxy for a Wi-Fi network on Android, its limits and when to use a client app.
Add a SOCKS5 or HTTP proxy with login in Postern on Android; HTTP port 2222, SOCKS5 port 3333.
Add a Proxy302 SOCKS5 proxy to v2rayNG on Android, test the connection and check your exit IP. HTTP-only datacenter IPs: use Postern, or get a SOCKS5 one.
Chrome has no SOCKS5 login, but a static ISP per-IP lease also works on HTTP port 2222 with the same login.
