If you still have assets on the Morelogin fingerprint browser, hurry to transfer them, related wallets should be abandoned and regenerated, they cannot be used anymore!!

Several fingerprint browsers have experienced real security incidents between 2025 and 2026.

The most serious incident was the supply chain attack on AdsPower around January 2025: hackers implanted backdoors by tampering with/replacing wallet plugins such as Metamask in the Chrome extension store within the browser (or by forcing update mechanisms), leading to the theft of a large amount of users' encrypted assets, with losses reported between $4.1 million and $5 million (the figures vary slightly from different sources).

This is one of the most publicly acknowledged and impactful events in the industry.

A summary of the current security status of fingerprint browsers in one sentence (March 2026):

The larger the companies/brands/user groups (AdsPower, Bit Browser, and later Morelogin), the more likely they are to become targets of hacker attacks; the more niche/local priority tools may have smaller leakage scales but often have weaker functions and fingerprint quality.

There is no absolutely secure fingerprint browser, only relatively safer usage methods, especially for markets that often require large amounts of capital participation in projects, fingerprint browsers are not the safest choice.

A gentleman does not stand under a dangerous wall.

The simplest and relatively safer method is still the native Chrome multi-open + extension solution (still recommended for low to medium risk scenarios in 2026)

I. Goal:

Fingerprint leakage risk is extremely low (because it does not rely on third-party cloud/client), IP is independent, operational costs are low, no need to pay for fingerprint browsers, as long as manual operation is sufficient, memory is enough, and there are no limits on the number of environments.

II. Core principles (security ranking from high to low):

1. All profile data is stored 100% locally, never enable any cloud sync!

2. Each profile must be forcibly bound to an independent residential/mobile proxy IP (SOCKS5 preferred)!

3. Never install any wallet plugins (Metamask, etc.) in the browser when dealing with large amounts of capital; wallets should use independent hardware/dedicated clean browsers!

4. The security of the computer itself comes first (clean system, antivirus, UAC, do not click on unknown software sources)!

III. Detailed steps (common for Win/mac, verified effective in 2026)

1. Create multiple completely independent Chrome user profile folders

- Do not use Chrome's built-in "Add user" (tested that isolation is not thorough; some underlying data information is still partially shared)

- Instead, directly copy using the following command line/shortcut method:

```

"C:\Program Files\Google\Chrome\Application\chrome.exe"

--user-data-dir="D:\ChromeProfiles\Acc1"

--no-first-run --no-default-browser-check

--disable-sync --disable-features=Sync

--disk-cache-dir="D:\ChromeProfiles\Acc1\Cache"

```

- Copy multiple shortcuts, change Acc1 to Acc2, Acc3 ……

- macOS use `/Applications/Google Chrome.app/Contents/MacOS… Chrome` + Same parameters

- Each shortcut is an independent sandbox, almost equivalent to different computer environments

- The Chrome store can still find ZeroOmega, SwitchyOmega fork version, or Simple Proxy, etc.

- Each Chrome instance should install plugins separately (because the data directories are independent)

- Create dedicated scenarios in each instance:

- Only fill the corresponding account's exclusive residential IP (SOCKS5 with authentication is best)

- Check "Global Mode" or "Auto-Switch Rules" (Recommended rule mode: only proxy for target domains)

- Turn off WebRTC (usually has a switch in the extension)

3. Other key security reinforcement settings (must be done for each profile!)

- chrome://settings/ → Privacy and security → Turn off "Auto-fill passwords" and "Payment methods"

- Turn off all sync items in "Sync and services"

- Search chrome://flags/ and disable: #enable-experimental-webassembly-features (reduce fingerprint points)

- Install uBlock Origin + ClearURLs + Cookie AutoDelete (automatically delete cookies)

- Never install or authorize any wallet/transaction/signature plugins

- Recommended additional installations: Canvas Defender / Trace (lightly disguises Canvas, but don't be too aggressive)

4. IP selection and binding suggestions (survival rate ranking)

- Preferred: Exclusive static residential IP (ISP type) > Mobile 4G/5G proxy > Rotating residential

- Avoid: data center IPs, free/low-quality S5 (easily associated)

- Each profile's IP location, time zone, language, manually set to match (for example, if using a US IP, set the US time zone + English)

- Cheap low-cost recommendation webshare website

5. Daily usage discipline

- One Chrome window for one account only, never open multiple windows for mixed use

- Regularly clear cache (or use Cookie AutoDelete to clear automatically)

- Do not log into personal real accounts/emails/payments in these browsers

- Regularly restart the computer + antivirus scans

IV. Summary of the pros and cons of this method:

- Advantages: Zero third-party client/cloud risks, fingerprints closest to real Chrome, lowest cost (only buy proxy), very low probability of being attacked by the supply chain

- Disadvantages: Fingerprint disguise ability is weak (Canvas/WebGL/fonts and other advanced fingerprints are basically naked), slightly troublesome for manual management, especially when running hundreds or thousands of accounts, not suitable for high-risk platforms (TikTok/FB ads heavily monitored)

- Additionally, using Google multi-open does not mean 100% security! You must also pay attention to the security of your mnemonic phrase backup and wallet authorization and other operations, and have sufficient security awareness!!

When the capital amount is small, fingerprint browsers can still be used, after all, they are convenient, quick, and save time, even if stolen, the loss cost is limited.

When the capital amount is large, you must carefully consider capital security. Using Google multi-open is more stable, dyor～
