How to Use Residential Proxies via Username:Password?

B2Proxy supports rapid extraction and utilization of dynamic IP addresses via simple username/password authentication. This article provides a detailed walkthrough of the complete process of retrieving a proxy through the dashboard, covering the selection of proxy geographic location, ASN-specific configuration, session type settings, sub-account binding, and proxy host selection—enabling you to get started quickly.

​

I. Basic Setup Steps

​

1. Select Proxy Location

Country/Region: Choose from the list (e.g., US). State-City (Optional): Refine location (e.g., Los Angeles, California). If you wish to filter by network operator (ASN), click the “Disable ASN” toggle in the upper-right corner and switch it to “Enable ASN ”. Once enabled, an ASN selection box will appear, allowing you to choose the target ASN from the list.

​

2. Set Session Type

Rotating IP: Auto-rotates IP per request (ideal for scraping/data collection). Sticky IP: The IP remains fixed for a period of time (5 minutes by default), suits account management).

​

3. Bind Sub-User

Select an existing sub-user or create one to assign proxy permissions.

​

4. Select Hostname

Based on your network IP, select the nearest server. You can also manually choose other nodes.

​

II. Proxy Generation & Testing

​

5. Test Connectivity (Optional)

Run in Command Prompt: curl -x host:port -U “username:password” ipinfo.io (Replace with your testing command)

​

6. Select Output Format

Proxy information usually includes: Host, Port, Username, and Password.

​

7. Set the Number of Proxies

Enter the number of IPs needed (e.g., 100), click 「Generate」.

​

8. Get Proxy List

After generation, copy individual proxies from 「Proxy List」, or export as TXT/CSV for bulk use.
