Separate Windows Accounts Are the Real Lock on a Shared PC
An extension guards Chrome's window. A Windows account guards the building. If several people share one PC, this ten-minute setup is the protection that actually holds — with its two honest limits stated plainly.

Ask a simple question: where does your Chrome profile physically live? In a folder inside your Windows user folder. So the lock that matters is the one Windows puts on that folder — and Windows only does that when each person has their own account. This page sets that up and tells you exactly where the wall ends.
Settings — Accounts — Other users (the setup that actually protects you)
☑ Your account — Administrator or Standard, protected by a password or PIN
☑ Family member account — Standard, their own password
☑ Office staff account — Standard, their own password
☐ One shared account called User with no password — the setup to retire
Can another standard account open your Chrome folderNo — Windows blocks it
Can a local administrator force accessYes, with effort
The target setup for a shared PC — one protected account per person, no shared no-password login. Panel recreated for illustration.

Why the Windows Account Is the Real Wall
Your Chrome profile lives in a folder inside your Windows user folder: C:\Users\YourName\AppData\Local\Google\Chrome\User Data. Windows protects each user's folder with file permissions. A different standard Windows account that clicks into that folder gets a plain access denied — no tools, no tricks, just no.
That is a completely different class of protection from a browser extension. The extension guards Chrome's front door; the Windows account guards the whole house, including the files themselves.

Set It Up in Ten Minutes
Open Settings → Accounts → Other users and add an account for each regular user of the PC — family member or staff.
Keep their accounts as Standard user. Only your own account needs to be administrator, if any.
Set a password or PIN on your account: Settings → Accounts → Sign-in options.
Move each person's Chrome usage to their own Windows account. Their Chrome profile is created fresh inside their own folder, automatically separated and protected.
Press Windows + L every time you leave the desk. Make it a reflex, like locking a car.

The Honest Limits of the Wall
Two honest caveats. First, a local administrator can take ownership of files and force a way in — so do not hand out admin accounts casually, and on an office PC remember the IT admin is, by design, able to get in. Second, the wall only holds while your session is locked or signed out. An unlocked, unattended session is an open door no matter how good the accounts are — which is why the Win + L habit in step five matters more than any software on this page.

Combine It With the Extension for Two Layers
Once the accounts are separate, add the Browser Lock extension from the main video as a second layer for the moments that remain: you are logged in, you step away for two minutes, a visitor is alone with the screen. The Windows lock covers the serious cases; the extension covers the casual ones without you having to sign out twelve times a day.
🔴 The one failure mode: perfect accounts plus an unlocked screen equals no protection at all. If you change only one thing after reading this page, make it the Win + L habit.

Do I need a Microsoft account for separate Windows accounts
No. Windows 10 and 11 both allow local accounts for other users, though the option is tucked behind a couple of extra clicks during setup. A local standard account gives exactly the same folder protection for Chrome data.
Will separate accounts slow down a shared family PC
Not in any way you will feel. Switching users takes a few seconds with fast user switching, and each person's desktop, files and Chrome stay exactly as they left them. The PC only needs enough disk space for each person's own files.
Someone in my home is the administrator. Am I protected
Mostly, for everyday privacy — an admin still cannot casually browse your folder without changing ownership, which leaves traces and takes effort. But strictly, an administrator can force access. If that level of trust is not there, the data should not live on that PC.
