Cookie Isolation is a browser security technique that keeps cookies completely separated across different browser environments or accounts.
In a standard browser, if multiple accounts share the same cookie storage, websites can easily detect them as the same user, leading to account linkage.
With cookie isolation, each account has its own independent cookie storage—similar to logging in from separate devices—making it much harder for platforms to detect multi-account activity.
Example:
A cross-border e-commerce seller manages multiple Shopee and eBay stores.
In a normal browser, cookies mix together, triggering platform security checks and store bans.
With MasLogin Antidetect Browser’s Cookie Isolation, each account gets its own cookie storage environment, as if they were running on different computers—significantly reducing the risk of detection.
Cookie Isolation is essential for multi-account management and anti-detection strategies.Combined with MasLogin Antidetect Browser’s environment isolation and fingerprint spoofing, it allows users to run multiple accounts safely and efficiently on the same device without the risk of cookie-based bans.
