Every proxy service has to authenticate you somehow. There are two mainstream methods, and the choice affects how you operate.
IP Whitelisting
You give the proxy provider your public IP, they whitelist it, and any connection from that IP is automatically allowed. No credentials to manage. Drawback: if your IP changes (home ISP, mobile, VPN), you have to update the whitelist.
Username + Password
You embed credentials in your client (browser, script, app). Works from any IP. Drawback: credentials leak in code repos and logs if you are not careful.
When to Use Which
- Stable office/home connection → IP whitelist (cleaner)
- Traveling / dynamic IP / multiple machines → Username + password
- Sharing across a team → Username + password with per-seat accounts
Styxproxy Default
Both methods are supported. Default is username + password for flexibility. Add IP whitelist as a second factor for tighter security.
