Browsing privacy on a shared or family computer

One computer, several people — a partner, kids, roommates. Chrome and your operating system have real tools for keeping each person's browsing their own, without drama and without anyone reading over your shoulder in the history page. Here are the layers, from quickest courtesy to the only real wall.

Layer 1: give each person their own Chrome profile

Profiles are Chrome's built-in way to split one browser between several people. Each profile keeps its own history, saved passwords, autofill, bookmarks, and extensions — so your searches never appear in anyone else's address bar.

1. Click the profile chip in Chrome's top-right corner — the small circle with your initial or photo, just left of the ⋮ menu.
2. In the panel that opens, click Add new profile (some versions label the button simply Add).
3. Choose Sign in if this person wants to use a Google account, or Continue without an account for a purely local profile.
4. Pick a name and a color — the color tints the window frame, which makes it obvious at a glance whose Chrome is open — and keep Create a desktop shortcut ticked so each person can open their own Chrome directly.
5. Repeat for each person. Switching later is the same chip: click it and pick a name.

The honest caveat: profiles are a courtesy, not a lock. Chrome has no profile passwords — anyone sitting at the keyboard can click the chip and switch into yours. Profiles keep people from stumbling onto each other's browsing; they don't stop someone who goes looking.

Layer 2: a guest window for borrowers

When someone asks to borrow the computer "for a minute," don't hand them your profile — hand them a guest window. Click the profile chip, then Open Guest profile. A guest window can't see your history, passwords, or autofill, and when the last guest window is closed, everything browsed in it is deleted from this computer. Nothing to clean up on either side.

Layer 3: incognito for your own one-off private sessions

For a session you don't want saved at all, open an incognito window: Ctrl+Shift+N (on a Mac, ⌘+Shift+N). Chrome won't record the history, cookies, or form entries once every incognito window is closed. Its limits are real, though: it does nothing about the pages you visited outside it, and it hides nothing from the network you're on — the guide to what incognito doesn't hide spells out exactly where it ends.

Layer 4: clean up what already happened

Layers only help going forward. For visits that are already saved — the porn or NSFW pages sitting in a shared profile's history right now — two routines cover it:

1. Open chrome://history (Ctrl+H, or ⌘+Y on a Mac), use the Search history box to find the site, tick each entry, then press Delete and confirm with Remove. The guide to deleting porn from Chrome history walks through this in detail, including the searches people forget to run.
2. Clear the address bar's own memory: type until the suggestion appears — say, late-night-video.example after a single letter — highlight it with the ↓ arrow key, and press Shift+Delete (on a Mac, Shift+Fn+Delete). Suggestions can outlive the history entries they came from; the address bar suggestions guide covers the stubborn ones.

Layer 5: separate accounts on the computer itself

Everything above is politeness between people who share a login. Separate operating system accounts, each with its own password, are the only layer that actually locks — each account gets its own desktop, its own files, and its own Chrome that nobody else can open.

1. Windows: open Settings → Accounts → Other users (on Windows 10, Family & other users) and choose Add account. Give each account its own password.
2. Mac: open System Settings → Users & Groups → Add Account… — macOS asks for an administrator password first.
3. Then make locking a habit whenever you step away: Win+L on Windows, Ctrl+⌘+Q on a Mac, and on Linux your desktop's lock shortcut (often Super+L).

What the manual layers miss

Being honest about the routine above:

• Every layer depends on remembering. The right profile, the right window, the cleanup afterwards — forget once and the visit is saved in a history other people can open.
• Autocomplete resurfaces things at the worst moment. One letter typed in your profile — by you or by whoever borrowed the chair — and the address bar offers a suggestion you thought was long gone.
• One skipped cleanup undoes weeks of care. The routine only works at 100%. A single missed evening leaves entries sitting there until the next time you think to look.
