How to Auto-Switch IPs for Multiple Accounts without Getting Blocked

Nowadays, proxy assistants have almost become essential tools for cross-border e-commerce and social media operations. However, many people clearly buy proxies and install assistants, yet their accounts still get banned or linked.

Even after changing IPs, accounts still get banned; even when the proxy is connected, platforms can still identify that the same group of people is operating the accounts. This is because many users overlook critical details during use.

Next, we will explain in detail how to properly set up automatic IP switching, when you should switch IPs and when you shouldn’t, and whether relying solely on IPs can truly prevent account linking.

I. Why Are Accounts Still Linked Even When Using Proxy IPs?

Simply changing IPs does not equal preventing account linkage. Today, platforms no longer judge account association based only on IP addresses, but on a complete set of environment fingerprints, including:

•  IP address and geolocation

•  Browser fingerprint detection (Canvas, WebGL, fonts, time zone, etc.)

•  Network environment stability

•  Abnormal behavioral patterns

Many people simply turn on a proxy assistant, letting the IP change constantly while the browser fingerprint remains the same. From the platform’s perspective, this is even more suspicious.

Therefore, a proxy IP assistant is only the foundation—the key lies in how you use it and what you combine it with.

II. IP Proxy Assistant: The Correct Setup Approach

1. Choose a Proxy Assistant That Supports Automatic Switching

Most mainstream IP proxy assistants now support the following modes:

•  Scheduled automatic IP switching

•  Changing IP each time the browser restarts

•  Manual one-click switching

If you operate multiple accounts, it is recommended to choose a proxy assistant that can be bound to browser profiles rather than using a global system proxy. This allows different accounts to use different IPs without affecting each other.

2. Always Perform IP Address Checks Before Use

Don’t rush to log into accounts—the first step should always be testing. You can check whether an IP is “clean” in the following ways:

•  Online IP lookup: Confirm whether the IP is real and whether it is a data center IP

•  IP address detection: Check whether DNS or WebRTC leaks your real IP

Many beginners overlook this step, resulting in situations where the proxy is connected but the real IP is still detected by the platform—making the proxy useless.

III. Practical Tips for Automatic IP Switching

Automatic IP switching is not better when done more frequently—this point is crucial. A reasonable switching strategy is:

•  One account = one fixed IP

•  Do not frequently change IPs for the same account

•  Different accounts must be completely isolated with different IPs

If you are using dynamic residential proxies, you can set:

•  Automatically switch IP each time the account browser is opened

•  Release the IP when the browser is closed

Instead of switching IPs every few minutes, which can easily trigger risk control mechanisms.

IV. IP Detection Is Only the First Step—Browser Fingerprint Checks Matter More

An IP is like a house number, while a browser fingerprint is like your face. Platforms use browser fingerprint detection to determine:

•  Whether these accounts are operated from the same device

•  Whether there is bulk or automated behavior

•  Whether virtual environment characteristics exist

This is where fingerprint browsers combined with fingerprint detection tools are required.

How to Use the ToDetect Fingerprint Query Tool?

After setting up your environment, it is strongly recommended to use the ToDetect fingerprint query tool for a comprehensive check, including:

•  Browser fingerprint uniqueness

•  Whether IP and time zone match

•  Whether WebRTC or Canvas shows anomalies

•  Potential environment conflict risks

With ToDetect fingerprint queries, you can identify issues in advance instead of regretting it after your account gets banned.

V. A Complete Multi-Account Anti-Linking Solution

If you operate multiple accounts long-term, here is a relatively stable setup recommendation:

•  Fingerprint browser (independent environment for each account)

•  IP proxy assistant (bound to the corresponding browser)

•  IP address checks + online IP lookups before going live

•  Use the ToDetect fingerprint query tool for environment health checks

•  Maintain consistent account behavior and avoid frequent device or IP switching

The advantage of this approach is a stable account environment, reasonable IP usage, and non-conflicting fingerprints—making it difficult for platforms to find issues.

VI. Commonly Overlooked Anti-Linking Details

•  Do not log into multiple accounts in the same browser

•  Public Wi-Fi + proxy = high risk

•  Avoid frequently clearing cache or reinstalling plugins

•  Ensure IP country, language, and time zone are consistent

These details may seem minor, but they are all positive factors in risk control systems.

Conclusion

An IP proxy assistant is just one part of the overall anti-account-linking system. Truly secure practices involve: IP isolation + browser fingerprint isolation + behavior isolation.

As long as you understand the logic of automatic IP switching and combine it with the ToDetect browser fingerprint detection tool, managing multiple accounts is not as difficult as it may seem.

If you are currently troubled by frequent account issues or unstable environments, consider starting with proper proxy assistant settings and gradually building a solid foundation.
