Q1. What is a proxy?
A proxy is an intermediary server between your device and the internet. It receives your network requests, forwards them to the destination server, and then returns the response back to your device. Through this process, the destination server can only see the proxy server’s IP address and cannot obtain your real IP. Key benefits include hiding your real identity, accessing geo- or permission-restricted content, and improving the security of online operations.
Q2. What are the common proxy types?
By protocol
- HTTP proxy: Supports only the HTTP protocol and can handle web-browsing requests, but cannot handle other request types such as HTTPS or FTP.
- HTTPS proxy: Designed for HTTPS and supports encrypted transmission, making it suitable for scenarios that require data security (such as account logins and payment actions).
- SOCKS proxy: A general-purpose proxy that can handle multiple protocols and traffic types such as HTTP, HTTPS, and FTP. The mainstream SOCKS5 version also supports authentication and UDP traffic.
By anonymity
- Transparent proxy: Exposes the user’s real IP to the destination server. It only provides basic forwarding and does not hide identity.
- Anonymous proxy: Hides the user’s real IP, but the destination server can detect that a proxy is being used.
- High-anonymity proxy (Elite proxy): Hides the real IP and disguises traffic as normal user access, so the destination server cannot detect the presence of a proxy.
Q3. How do I choose the right proxy?
- Security: Prioritize proxies that support encrypted transmission (such as HTTPS and SOCKS5) to avoid data being stolen or tampered with during transmission.
- Speed and stability: Choose proxy servers with low latency and high uptime to prevent lag or disconnects from affecting browsing or work efficiency.
- Anonymity: Choose an appropriate anonymity level based on your needs. For everyday privacy, an anonymous proxy is enough; for deep identity hiding (such as cross-border business), choose a high-anonymity proxy.
- Server location: If you need to access content in a specific region (such as a country’s streaming services or local websites), choose proxy servers with nodes in that region.
- Provider reputation: Prefer reputable, stable providers and avoid free proxies due to potential security risks (such as data leaks or malicious use).
Q4. Can I use the internet without a proxy?
Yes. When creating a browser profile, choose “No proxy (direct local network)” to access the internet via your local connection. However, using a proxy can be more advantageous in certain scenarios:
- In public networks (such as café Wi-Fi), a proxy can improve security;
- When you need access to geo-restricted content (such as overseas academic resources), a proxy can help bypass restrictions;
- When privacy is a priority, a proxy can hide your real IP.
Q5. What proxy types does MasLogin support?
MasLogin currently supports three common proxy types: HTTP, HTTPS, and SOCKS5, which cover typical web browsing, encrypted transmission, and multi-protocol traffic needs.
Q6. Why configure a proxy in MasLogin?
Configuring a proxy in MasLogin is mainly to combine the fingerprint browser’s capabilities and achieve “privacy protection + extended functionality.” There are 5 key benefits:
1. Stronger privacy protection: A proxy hides your real IP. Combined with browser fingerprint simulation, it provides dual protection for your online identity.
2. Bypass geo restrictions: Using a proxy IP from the target region allows access to content limited by geography (such as region-specific platforms and resources).
3. Improved security: Encrypted proxies like HTTPS and SOCKS5 help prevent data theft in unsafe environments such as public Wi-Fi.
4. Reduce online tracking: A proxy plus isolated browser profiles greatly reduces the risk of platforms tracking and linking your accounts.
5. Multi-account operations: Assigning a dedicated proxy IP to each browser profile helps prevent multiple accounts from being flagged as linked due to sharing the same IP, lowering ban risk.
Q7. How should I handle a proxy connection failure?
You can troubleshoot proxy connection failures in the following steps to identify the root cause:
1. Double-check proxy settings: Verify the server address and port. If authentication is required (username/password), confirm the credentials are correct to avoid failures caused by incorrect input.
2. Validate the proxy itself: Use a browser or a proxy testing tool (such as ip111.cn) to test the proxy independently. If the tool test also fails, the proxy may be invalid or expired—contact your IP provider.
3. Check your local network environment: Confirm your local network (Wi-Fi, broadband, etc.) is working normally. If you are using an overseas IP proxy, note that networks within mainland China (excluding Hong Kong, Macau, and Taiwan) cannot directly access overseas IPs. You may need an overseas network environment via VPS, international dedicated lines, etc., before trying the proxy again.
4. Switch proxy server nodes: If the current proxy fails due to server issues or congestion, try switching to another healthy proxy node and test again.
5. Confirm the proxy matches the usage scenario: If you purchased an overseas IP proxy in China, confirm you meet the “external network environment” prerequisite to avoid failures caused by a mismatched environment.
6. Seek official technical support: If none of the above works, contact your proxy provider to check the proxy service, or reach out to MasLogin in-app support for targeted help.
Q8. Does MasLogin sell proxies?
MasLogin does not directly sell proxies. Its core role is as a fingerprint browser tool provider. On the MasLogin website, Partners recommends proxy providers.
Q9. Can I apply the same proxy to different browser profiles?
Yes, you can apply the same proxy to multiple browser profiles. However, for better stability and account security, it is recommended to assign a unique proxy IP to each profile to reduce the risk of accounts being linked due to sharing the same IP.
Q10. Do I have to use a proxy to create or open a profile?
No. MasLogin supports profiles without proxies. But if you operate cross-border platforms (such as Facebook, Shopee, or TikTok), it is recommended to use a high-quality proxy to reduce linking and ban risks.
