Identity-based attacks now top the fraud worry-list for 70 % of enterprises, according to Arkose Labs’ 2024 device-ID study. Marketplaces react by linking anything that looks like the same shopper—device hashes, WebRTC IPs, even audio stacks—then auto-suspending related accounts. Sellers who can’t prove the hardware behind each login lose the Buy-Box and, sometimes, the account.
MuLogin steps into that gap by letting one computer masquerade as hundreds of independent devices, each sealed off in its own “virtual browser” container.
How a MuLogin profile is born
Click “Add Browser” and the desktop client spawns a container that keeps its own cookies, localStorage, cache files and TLS state. MuLogin’s docs stress that no artefact crosses the wall between profiles, achieving “multi-account secure login without being detected.”
A fresh profile launches in roughly five seconds and burns only 6-8 % CPU on an eight-core VPS, light enough to leave a hundred sessions open during peak shifts, according to internal benchmarks shared with partners.
Fingerprints: swapping the digital DNA
Modern risk engines scrape dozens of entropy points—GPU strings, WebGL canvas hashes, Speech-Synthesis voices—to decide whether a visitor is new or returning. MuLogin exposes sliders for more than 40 of those parameters and lets users pin, randomise or bulk-import values that match the proxy in use. Its native approach is simple: the site can read whatever it wants, but the browser swaps in a synthetic fingerprint before the script returns.
Canvas, WebGL and the “near-zero” duplicate rate
A bare Chromium driver renders an identical pixel map every time, an instant neon sign for bot-defence suites. MuLogin injects microscopic noise into Canvas and WebGL draws so that checksum tests see each profile as a one-off while the human eye notices nothing. Anecdotal Pixelscan reports posted by power users show duplicate rates falling below 1 % after the switch.
WebRTC modes keep the LAN IP out of sight
WebRTC is infamous for leaking a real local address even behind a proxy. MuLogin offers three toggles—replace, disable and proxy-safe—so growth teams can decide whether to publish a spoofed internal IP or silence the API altogether. For geo-fenced ad campaigns that pay only on country-match, that single dropdown often decides whether clicks are billable.
Cookies: sealed jars, exportable on demand
Fingerprint variety is pointless if two sessions share a cookie jar. Each MuLogin profile therefore owns an encrypted vault that never touches the host file system. The built-in importer/exporter lets teams clone warm sessions or hand them to a colleague without zipping the whole profile bundle, an edge case that matters when a TikTok shop needs 50 buyers online in under an hour.
Clean-up routines after every close
When a profile shuts down, the client wipes temp files, rewrites the storage-salt and confirms the cull with MuLogin’s REST endpoint. The vendor’s free-trial docs claim “near-zero residue,” and spot checks on local SQLite stores back that up.
Automation hooks: REST, Selenium, Playwright
MuLogin’s local API listens on port 50325 by default. A single POST /profile/start call returns a DevTools URL that Selenium or Playwright can attach to, so QA or scraping scripts run headless without any GUI clicks. The docs list more than 20 helper calls—from openNewTab to exportCookies—and allow batch profile creation for large test matrices.
Plans, seats and the three-day test drive
Pricing lines up with headcount. The Starter tier costs $59/month for 100 profiles and one sub-account; Growth bumps that to 200 profiles and five seats at $99; Pro and Enterprise jump to 500 and 3 000 profiles for $209 and $499 respectively. All paid plans include unlimited fingerprint templates and full API access. New sign-ups get a three-day free trial capped at five profiles—enough to run a PixelScan test or a small ad set before the card is charged.
Early-market verdict
Trustpilot shows only seven public reviews, but they average 4.1/5, a softer-launch signal that stability is meeting user expectations even if volume is still tiny next to Gologin or AdsPower. Meanwhile, Bright Data’s 2025 browser roundup lists MuLogin as one of the few tools that isolates cookies, localStorage and sessionStorage by default—a feature several pricier rivals hide behind enterprise SKUs.
Bottom line
If half of all account bans trace back to detectable linkages—and Arkose’s device-ID data suggests that is no exaggeration—the safest path is to make every login look like it came from an entirely different desk. MuLogin does that without demanding multiple laptops, VMs or complex VNC routing.
One fingerprint, one cookie jar, one clean session: in 2025 that sounds less like paranoia and more like standard operating procedure for anyone running multiple e-commerce or ad accounts at once.
