Credential format
The dashboard delivers credentials as host:port:username:password records. Each line authorises a single order — the entire bandwidth or IP allocation you bought.

The host and port are stable. The username is opaque — treat it as random. The password is a high-entropy secret; rotate it through the dashboard if it leaks.
Two ways to authenticate
The proxy gateway accepts both URL-embedded credentials and a standard Proxy-Authorization: Basic header. They're equivalent; pick the one your client library prefers.
# Embedded in the proxy URL
$ curl -x http://USER:[email protected]:8080 https://example.com
# Header-based — useful when secrets shouldn't sit in connection strings
$ curl -x http://gw.justproxies.online:8080 \
--proxy-user USER:PASS \
https://example.com
Per-order scoping
Each set of credentials is bound to one order. A residential 50 GB order has its own user/pass and pulls only from your residential balance. A static IP rental has its own user/pass and only authenticates against the IPs you rented.
That means a leaked credential cannot drain another order. Treat each as a single-purpose secret.
Credential lifetime
- Rotating products — credentials work as long as the order has remaining balance. Once the bytes are spent, the credentials stop authenticating. Place a new order; you get new credentials.
- Static IPs — credentials work for the calendar month period you rented. They expire automatically at month-end unless you place a renewal order before expiry.
Sticky-session token
Append -session-XXXXXXXX to the username to keep the same exit IP across requests. The token is opaque — pick any 8-16 character ID. Two requests using the same token go through the same IP for as long as the session is alive (default ~10 minutes).
# Same exit IP for the entire login flow
$ curl -x http://cust_2c4f9a-session-A1B2C3D4:[email protected]:8080 \
https://target.com/login
Full lifecycle and tuning lives in Sticky sessions.
Static IP credentials
Static IPs ship with one credential per IP. The host and port are fixed; the username is bound to that specific IP, so authenticating with the credential always exits through the same IP.

Rotating a leaked credential
If you suspect a credential is compromised, open the order in the dashboard and click Rotate password. The new password takes effect within a minute and the old one is invalidated. Bandwidth balance is preserved.
