Quick answer: MoreLogin works by creating isolated browser profiles, each with its own canvas fingerprint, WebGL signal, cookie storage, and network route. When you open a MoreLogin profile, websites see a distinct device identity — not the same hardware and browser as your other profiles. Adding a residential proxy per profile completes the isolation by giving each session a unique IP address.
The Core Mechanism: Browser Profile Isolation
A standard browser — Chrome, Firefox, Edge — stores all cookies, history, and session data in one place. Websites can use that shared storage to correlate activity across tabs and logins. MoreLogin replaces this shared model with individual sandboxed profiles, each running in its own storage directory with its own configuration.
When you create a profile in MoreLogin, the tool generates a distinct browser identity for that profile. That identity includes a specific canvas fingerprint hash (what websites see when they run canvas rendering tests), a unique WebGL renderer string, a defined system font list, a configured screen resolution and timezone, and isolated cookie storage. From a website’s perspective, each profile appears to originate from a completely different device and browser installation.
How Fingerprint Isolation Works in Practice
The primary detection vector MoreLogin addresses is the browser fingerprint — the combination of signals a website’s JavaScript can read without asking for permissions. Canvas fingerprinting, specifically, draws a hidden image in the browser and reads the pixel output, which varies by hardware and software stack. Without anti-detect tools, every Chrome window on the same machine produces the same canvas hash. MoreLogin modifies this output per profile so each session returns a different result.
| Fingerprint Signal | Standard Chrome (Multiple Windows) | MoreLogin Profiles |
|---|---|---|
| Canvas hash | Identical across all windows | Unique per profile |
| WebGL renderer string | Same GPU string reported | Configurable per profile |
| Cookie storage | Shared per browser profile | Fully isolated per profile |
| Timezone | System timezone reported | Set to match proxy city |
| IP address | Same IP for all windows | Proxy assigned per profile |
Where Proxies Fit In
MoreLogin handles the browser fingerprint side of isolation — it doesn’t replace proxies. Every profile still shares your machine’s real IP address unless you assign a proxy to it. On ad platforms and marketplaces that compare IP addresses across account logins, running multiple MoreLogin profiles without per-profile proxy assignment leaves IP-based correlation intact.
The standard setup pairs each MoreLogin profile with one dedicated residential proxy. That proxy’s city, timezone, and language should match the profile’s configured settings. A profile set to Chicago timezone connected to a UK proxy creates a timezone-IP mismatch — a signal that careful detection systems flag. Consistency between proxy city and profile configuration is as important as using proxies at all.
Setting up MoreLogin profiles with clean fingerprints but connecting them all to one shared proxy or rotating proxy pool. Proxy rotation means multiple profiles periodically land on the same IP exit node — which reintroduces IP correlation even when the browser fingerprints are perfectly isolated. Dedicated residential proxies (one per profile, not rotating) prevent this. If proxy cost is a constraint, rotating proxies with sticky sessions — fixed IP per session rather than per request — are a workable middle ground.
Team Workflow: How MoreLogin Handles Multiple Operators
Paid MoreLogin tiers add team functionality — shared workspaces where multiple operators can access and launch profiles, with role-based access controls limiting which team members can view or modify which profile sets. This matters for agencies where account managers, media buyers, and administrators all touch the same profile fleet.
When team members launch the same profile simultaneously on different machines, MoreLogin handles the session sync. The practical implication: assign each profile to a primary operator in your tracking doc, and treat simultaneous multi-operator access as an exception rather than a workflow pattern. Overlapping sessions on the same profile can create session state conflicts that manifest as unexpected logouts on the platform side.
For larger agency operations, RoxyBrowser offers comparable team workflow capabilities with per-profile fingerprint isolation — worth trialing in parallel on your strictest platforms to compare how each tool’s fingerprint quality holds up on the specific backends your clients use.

FAQ: How Does MoreLogin Work
Does MoreLogin include proxies in its plans?
Some MoreLogin plans include a proxy marketplace or built-in proxy purchase option, but the anti-detect browser itself and the proxies are separate components. For strict platforms, sourcing residential proxies independently from a reputable provider — and assigning them one-per-profile — gives more control over proxy quality and rotation timing than relying solely on bundled proxy options.
Is MoreLogin a VPN?
No. MoreLogin is an anti-detect browser — it modifies browser fingerprint signals so each profile appears as a distinct device. A VPN changes your IP address but doesn’t touch browser fingerprints; all accounts accessed through a VPN still share the same canvas hash, WebGL string, and hardware signals. The two tools serve different purposes and are often used together.
Can MoreLogin run browser automation?
MoreLogin supports API and automation integration for teams running programmatic workflows — bulk profile creation, proxy assignment automation, and session launching via script. Check the current MoreLogin API documentation for specific integration details, as capabilities and supported frameworks vary by plan tier and are updated regularly.
What happens to profile data if MoreLogin’s servers go down?
Profile storage configuration varies by tool — some anti-detect browsers store profile data locally, others sync to cloud. For business-critical profiles, export cookie and session backups regularly regardless of where the tool stores data. A cloud storage dependency means a vendor outage affects your ability to access active profiles until service is restored.
