If your team still passes around passwords to “get someone into” an ad account, analytics suite, marketplace dashboard, or CMS, you’re carrying unnecessary risk—and wasting time. A team browser fixes that. Instead of handing over credentials, you share a live, permissioned browser session that your colleague can use as if they were logged in—while the password stays hidden. It’s cleaner for security, faster for collaboration, and easier to audit.
In this guide, we’ll unpack how a team browser works, why “share access, not credentials” should be your default, and how Sendwin—a cloud, multi-login browser—implements secure sharing with per-tab isolation, zero-trust execution, strong encryption, and global endpoints. You’ll also find plans, use cases, and a simple three-step “getting started” so you can try it today with minimal friction.
What is a “team browser”?
A team browser is a cloud browser that runs real desktop browsers on managed infrastructure and streams an interactive view to your device. Because the code executes in the provider’s environment (not on your laptop), you get zero-trust browser isolation by default—malicious pages never run locally on your machine. For multi-account work, each login can live in its own isolated tab, so you can open multiple accounts side-by-side (even on the same website) without cookie collisions.
Think of it like a secure, disposable workbench in the cloud. You spin up a fresh, clean browser for each task, log in once, and then decide who else (if anyone) can use that exact session—and for how long. Your device acts like the screen and keyboard; the sensitive stuff (credentials, cookies, page code) lives in Sendwin’s isolated environment.
Sendwin takes this model further for teams: you can share a running session (not the underlying credentials) with coworkers, put a timer on access, blur or block sensitive pages (e.g., billing), and revoke access instantly. Compared to passing passwords around or juggling shared vaults, you get tighter control and a far cleaner audit trail.
Quick distinction: You might see “credentialless iframes” in web platform docs. That browser feature is about embedding content without cookies. In a team browser context, “credentialless access” means your teammate never touches your password at all—they use a time-boxed, permissioned session you shared.
Why “share access—not credentials” is the safer default
Sharing passwords creates credential sprawl and never-ending “Who changed that?” moments. It invites password reuse, complicates MFA, and makes accountability difficult. When something goes wrong, you can’t easily attribute actions.
A team browser flips that script. You share a session link instead of a password. Your colleague completes the task and you can see when, how long, and—if you enable logging—what they did. When the work is done, you revoke the session and move on. No reset emails, no “please 2FA me,” no awkward vault invites. It’s faster for the team, cleaner for security, and vastly easier to explain to stakeholders.
How Sendwin’s Team Browser model works
Per-tab session isolation
Every tab runs in a separate container with its own storage, cookies, and identity. That lets you log into multiple accounts on the same platform simultaneously—no more log-out/log-in loops, no cookie bleed, and fewer cross-account mistakes. If you manage client accounts or operate several storefronts, this single capability can feel game-changing.
One-click session sharing (no passwords)
Need a teammate to jump into an ad account or CMS right now? Share the live session. They interact exactly as if they were logged in, but they never see the credentials. You can set a timer—30 minutes, an hour, a day—and you can blur or block sensitive pages before you hand off. When the task is complete, you revoke access with one click. Higher tiers add share-by-link, website session access, one-click share-all, block sessions, and auto-assign proxies for bigger teams that want standardized setups.
Encryption & zero-trust execution
Under the hood, Sendwin pairs AES-256 for symmetric encryption with RSA-2048 for asymmetric operations, applied per session. Combined with remote execution—pages run in the cloud; your device receives a safe stream—this zero-trust approach dramatically lowers endpoint risk from malware and phishing.
Privacy by design: no shared storage between tabs
Sendwin does not use shared storage across tabs, which cuts down on cross-tab tracking and accidental data carryover. For teams constantly switching accounts or environments, this “clean room” model keeps workflows tidy and more private.
Proxy & location controls + global endpoints
Attach your own proxies per session for IP/location anonymity and realistic geo testing—often more precise than a “blanket” VPN. Pair that with Sendwin’s global endpoints in the Americas, Europe, and Asia to keep latency low and experiences snappy for distributed teams.
Activity logging & audit trails
If compliance or accountability matters, a trail matters. With role-based access, session timers, share controls, and optional logging, you can give people exactly the access they need—no more, no less—and prove it later.
Who benefits most? Real-world use cases
Marketers & advertisers
Run multiple ad accounts side-by-side, test creatives in parallel, and invite contractors into a session without ever sharing the login. Match proxies and endpoints to the campaign region to preview geo-specific experiences. No more juggling profiles, private windows, or secondary browsers.
E-commerce sellers
Operate several shops across marketplaces in separate tabs, then bring a VA into a time-boxed session to process orders or update listings. Blur billing or owner-only pages and set a one-hour timer so access expires automatically.
SEO professionals
Perform multi-location SERP checks by assigning region-appropriate proxies to each session and selecting the closest endpoint. Keep environments clean between tests, and share a read-only or time-limited session with a client for quick review—no credential handoff.
Developers, QA & testers
Reproduce bugs by switching accounts with one click, keep staging or admin credentials quarantined, and dispose of risky sessions in seconds. Because execution is remote, you lower the risk to your laptop when exploring unknown URLs, staging builds, or third-party tools.
Remote workers & everyday power users
Juggle multiple Gmail, social, analytics, or project-management profiles without scripts or OS-level profiles. With per-tab isolation and one-click switching, context changes are smooth and you stay in flow.
Feature deep-dive (and why each one matters)
- Multiple logins made easy — Work across many accounts at once; teams often see dramatic time savings thanks to one-click identity switching and clean isolation.
- Session isolation on every tab — Prevent cookie/cache leakage, avoid accidental actions in the wrong account, and run true side-by-side comparisons for ads, copy, checkout flows, and more.

Best-practice checklist for secure access delegation
- Default to session sharing — Replace password handoffs with revocable session links.
- Blur/block first — Hide billing, owner settings, or sensitive data before you share.
- Match regions — Use proxies and endpoints that align with expected user locations to reduce flags and see what your customers actually see.
- One account, one tab — Rely on per-tab isolation instead of juggling local profiles or extra browsers.
- Audit & expire — Review activity and let sessions expire routinely to keep your environment clean and compliant.
FAQ (quick answers)
Is sharing online accounts with Sendwin actually safe?
Yes. You share a running session, not the password. Sessions are isolated per tab, encrypted end-to-end, and you control timers, blur/block settings, and revocation.
What happens to my device’s security?
Pages execute remotely and stream to your screen. That aligns with zero-trust browser isolation, which reduces the risk of malware or phishing reaching your device.
Can I simulate different locations?
Absolutely. Attach your own proxies per session and pick from global endpoints (Americas, Europe, Asia) for low-latency, region-accurate browsing and testing.
Do I need to install anything?
No. It’s agentless—launch everything from your dashboard. Images update nightly to maintain compatibility with modern sites and security patches.
Are there time limits?
On paid plans, there are no per-session time caps, so you can keep sessions open as long as you need. Timers are your control mechanism to limit access when you share with others.
How is this different from “credentialless iframes” I saw in developer docs?
“Credentialless iframes” are a web feature for loading embedded content without cookies. Here, “share access, not credentials” is about delegation via session sharing—your teammate uses your running session without ever touching your password.
