Proxy server settings tell your device or browser to use an intermediary server. It bridges your device and the internet. If you ask what proxy settings should I use, enter host, port, protocol, and credentials. Steps vary by operating system and browser.
A freelancer receiving proxy.example.com:8080, HTTP, user/pass can map each part below.
Setting | What it means | Where you get it | Example format |
|---|---|---|---|
Host | Host/IP address | Provider | proxy.example.com |
Port | Endpoint number | Provider | 8080 |
Protocol | HTTP or SOCKS5 | Provider | HTTP |
Username | Login | Provider | user123 |
Password | Secret | Provider | pass123 |
Bypass list | Direct addresses | OS | localhost |
What proxy settings should I use? Use HTTP proxy for browsers. Choose SOCKS5 only when apps can send credentials.
For proxy server settings, HTTP trades flexibility for broad browser support. If a SOCKS5 host in the Windows proxy field gives no connection, use HTTP. Chrome and Firefox cannot send SOCKS5 username/password.
Protocol | Best for | Limitation |
|---|---|---|
HTTP | Browsers, Windows field | Less general |
SOCKS5 | Non-browser tools | Browser credential limits |
Many proxy settings include a username and password. In Chrome, enter the HTTP host and port, then type the credentials into the authentication prompt, never sharing them in public places. OnlineProxy mobile proxies use this login method only. They run on 4G/5G carrier IPs with HTTP and SOCKS5. For that protocol, use Proxifier or an anti-detect browser.
The bypass list keeps localhost and local network addresses direct. For example, a developer excludes loopback so test sites open.
Before changing your proxy server settings, treat every unknown endpoint as a possible malicious proxy.
Before you save
For example, if a random forum endpoint causes ads and redirects, delete it.
Here is how to set proxy settings in Windows. The built-in field accepts HTTP only.
proxy.example.com and 8080.
If login is required, the browser or app asks later. To undo, switch the toggle off.
To change proxy server settings on macOS, open System Settings > Network, select Wi-Fi or Ethernet, click Details…, then open Proxies. These values apply to apps that use the system route.
On Ventura and later, this proxy configuration is applied by OK alone, while older System Preferences use Apply. Safari and Chrome use these values, but Chrome cannot send SOCKS5 credentials.

Chrome and Firefox usually follow system proxy settings. For example, a single Windows change can route both browsers automatically.
Chrome uses your system proxy server settings. To open the panel:
The --proxy-server flag takes no credentials. It is ignored if Chrome already runs unless you add --user-data-dir or quit first. Proxy-switcher extensions cannot add SOCKS5 authentication.
Firefox defaults to Use system proxy settings. To isolate this browser, configure it manually.
If the IP address does not change, the app may ignore system settings.
A hurried typo in proxy server settings can cause timeouts, login loops, or unchanged IP.
Symptom | Likely cause | Fix |
|---|---|---|
Timeout | Wrong host, port, protocol | Verify them. |
Endless login or 407 proxy authentication required | Bad credentials | Retype. A Chrome password typo can block pages. |
SOCKS5 host in Windows field | HTTP box | Use HTTP or a SOCKS5 auth app. |
Chrome flag ignored | Still running | Quit the browser or use separate profile. |
IP unchanged | Not saved or ignored | Save and restart app. |
Test with a free online proxy checker and reset proxy settings by switching it off or clearing fields.
Host, port, protocol, and credentials. Use HTTP for system settings and Chrome.
Enter them in your OS or browser, then verify.
No. The Windows field is HTTP-only. Use HTTP or a tool supporting SOCKS5 authentication.
Usually restart after saving. Switch the proxy toggle off.
Before saving your proxy server settings, confirm:
Keep the original values noted for quick rollback.
