1024Proxy’s dynamic residential IP service offers two authentication methods: Username & Password Authentication and IP Whitelist. What exactly are the differences between these two verification approaches? How should you operate and choose between them in practice? This article provides a comprehensive introduction—from principles to step-by-step instructions—to help you use 1024Proxy more smoothly and efficiently.
Username & Password Authentication is a common and fundamental identity verification method. When using an IP, users must include their username and password in the connection request. The proxy server verifies the credentials before granting access to network resources.
No fixed local IP required—works in any network environment
Flexible configuration, suitable for multiple users, devices, or automated program calls
Secure and controllable—passwords can be changed or accounts disabled at any time
Frequently changing terminal devices/IPs: e.g., using 5G on business trips, broadband at home, Wi-Fi at the office—your IP address changes often.
Shared use across multiple people/teams: e.g., multiple employees in a company sharing a pool of IPs, or distributing IPs to outsourced teams.
Temporary, short-term tasks: e.g., one-off data scraping or ad-hoc account registration tests.
Privacy-sensitive users: those who prefer not to share their real IP with the proxy provider.
Core Takeaway: Username & Password Authentication is best suited for “highly dynamic, non-fixed terminal, medium-security” scenarios.
Log in to the 1024proxy official website, purchase the appropriate dynamic residential traffic plan, and enter the dashboard.
In the dashboard, navigate to the Username & Password Authentication menu and click the Account Management button.
1024Proxy creates a default primary account. Click the +Add Account button to create new sub-accounts.
In the pop-up window, you can set the username, password, add a remark, and allocate (increase or decrease) the corresponding traffic package (in GB).
Sub-account management meets the needs for multi-account control and precise traffic allocation—ideal for studios or enterprises with collaborative workflows.
Click Confirm, and the new sub-account will appear on the account page, along with its current traffic usage.
Click the Go Use button to return to the authentication page.
Choose the account you wish to use.
1.Set Geographic Location: Filter by dropdown or enter values for country/region, state/province, and city.
2.ASN: In the global internet, networks are divided into Autonomous Systems (AS), each managed by a single organization (e.g., telecom operators, cloud providers, universities, companies) and assigned a unique number—this is the ASN.
Note: ASN and state/province/city filters cannot be used simultaneously—choose one.
3.Proxy Host: Forwarding machines in different regions affect IP performance. Choose a host closer to your target website to reduce latency and improve speed. 1024Proxy offers forwarding hosts in the US and Hong Kong—choose based on your primary target site’s location.
4.Session Type: Choose between Sticky IP and Rotating IP.
| Dimension | Sticky IP | Rotating IP |
| Definition | IP remains fixed for a set duration (1–120 minutes for 1024Proxy dynamic residential traffic) | IP changes automatically with each request/connection |
| Change Frequency | Fixed until session expires | Changes per request/connection |
| Core Advantage | Stable, maintains login state, continuous operations | High resource efficiency, load distribution, better privacy |
| Use Cases | Logins, form submissions, shopping cart operations—stateful tasks | Public data scraping, load testing, login-free crawling |
| Not Suitable For | High-frequency rotation needs | Tasks requiring persistent login or session state |
| Recommendations | Set reasonable duration; manually rotate sessions for new IPs when needed | Control request frequency; combine with country/city/ASN parameters for precise rotation |
5.Select Account: Choose from the sub-accounts created in Account Management to achieve precise traffic control.
6.Protocol Type: 1024Proxy supports HTTP(S) and SOCKS5. Use the provided cURL command to quickly test proxy extraction.
On Windows, press Win+R, type cmd, and paste the cURL command into the command prompt.
7.Output Format: 1024Proxy supports multiple protocol formats compatible with most third-party proxy tools:
Hostname:Port:Username:Password
Socks5://username:password@host:port
Username:Password@Hostname:Port
Hostname:Port@Username:Password
8.QR Code for Quick Copy: Scan the QR code with your phone to quickly input credentials—boosts workflow efficiency.
In the Data Statistics section, you can check your daily traffic consumption.
Click the Apply button, wait 1–2 minutes, refresh the page, and the Download button will appear. Click to download detailed daily traffic usage logs.
IP Whitelist is a password-free authorization method that offers a more convenient and efficient authentication experience. By adding your trusted local egress IP to the whitelist, the system automatically identifies incoming requests. As long as the request originates from a whitelisted IP, you can directly call the API and use proxies without including a username and password in each request—streamlining the configuration process. For users with fixed egress IPs, IP Whitelist is a more stable and secure option.
No credentials required: No need to expose usernames or passwords in code or tools
Simpler configuration: Ideal for fixed servers or cloud-hosted environments
Controlled access: Only whitelisted IPs can access proxy resources
Enhanced security: Restricts access by source IP, reducing unauthorized entry points
Better for automation: Fewer parameters to configure, lower error rates
Server/backend program calls: e.g., crawling scripts deployed on Alibaba Cloud or AWS with a fixed elastic public IP
High-frequency, large-volume requests: e.g., millions of daily data scraping tasks, 24/7 product price monitoring, large-scale SEO keyword rank queries
Office/company fixed networks: Employees working under the same office Wi-Fi, sharing IPs for business operations
Security-sensitive businesses: e.g., financial data scraping, compliance-bound automated tasks (e.g., Classified Protection requirements)
CI/CD pipelines and containerized deployments: e.g., GitHub Actions automated builds, Jenkins scheduled jobs, Kubernetes pod egress IP configuration
Core Takeaway: IP Whitelist is best suited for “fixed terminals, performance-driven, high-security” scenarios.
Before using IP Whitelist, confirm your current device or server’s public egress IP. You can check via an IP lookup website or run a command on your server.
Example using Windows Command Prompt:
Press Win+R, type cmd to open the command prompt, then enter:
curl -s ipinfo.io/ip
This will return your local public IP.
Log in to the 1024Proxy user dashboard, navigate to the IP Whitelist / Security Settings page, and add your public IP to the whitelist. Save your settings.
Note: Only public IPs can be added. If your IP changes, update the whitelist promptly—otherwise, you will lose access.
Once the whitelist is successfully configured, you no longer need to pass username/password parameters when calling the API. The system will automatically authenticate based on the request source IP.
Only add trusted, fixed IPs to the whitelist
Do not add dynamic IPs or public network IPs arbitrarily
Regularly review and remove unused whitelist IPs
For multiple servers, add each server’s respective egress IP separately
Error Codes When Using IP Whitelist
| Error Code | Meaning & Solution |
| 403 Forbidden | Request IP is not on the whitelist—verify your current egress IP matches the added one |
| 401 Unauthorized | Authentication failed—confirm whitelist configuration has been saved and applied |
If your IP is correct but still not working, try refreshing the whitelist configuration or contact customer support.
Username & Password Authentication and IP Whitelisting are suited to different business scenarios. For situations where the terminal IP frequently changes, choose password authentication; for scenarios with fixed IPs, opt for IP whitelisting. Password authentication and IP whitelisting are not mutually exclusive; for scenarios with strict security requirements, both verification methods can be enabled simultaneously to achieve dual verification, further enhancing security.
By following the instructions in this guide, you can successfully set up authentication and start using 1024Proxy’s high-quality, clean, and stable dynamic residential IPs to empower your business.
