You are on a support call, sharing your screen to fix a client's issue — and then you open your password manager to grab a credential. The vault appears on the shared stream: account names, site URLs, everything you are looking at. It is a small mistake with outsized consequences for you, your client, and your company.

Here is how to keep a password manager window out of screen shares and recordings on Windows — not blurred, not minimized, completely absent from the capture while you still use it normally on your own screen.

Why password managers are the most dangerous window to leak

Unlike a chat message, a password manager window is a structured record of your secrets:

• Every account name you use — a map of your online identity.
• Site URLs — what services you depend on.
• TOTP codes and generated passwords — often visible long enough to be read.
• Notes and credit-card fields — some managers keep payment data too.

A chat leak is embarrassing. A password-manager leak is a credential exposure that could be replayed later by anyone who captured the call.

What does not protect you

• Blur filters in the meeting app. They apply to a region you pick in advance — easy to forget, and some capture pipelines still record the pre-blur frames.
• Sharing only one window. One wrong click or Alt-Tab later, the vault is visible.
• Locking the vault before sharing. It protects nothing if you need to unlock it during the call — and you usually do.
• "Stop video" / "pause share". It relies on you noticing the moment before you open the vault. People do not.
• Password managers' own "hide from recording" toggles. Very few exist, and they do not cover third-party capture tools.

What actually works: capture exclusion

Windows allows a window to be excluded from screen capture. Such a window does not appear in Zoom, Teams, Meet, Discord, OBS — or any other screen-share or recording tool — while staying fully visible and interactive on your monitor. Normally only the app that owns the window can set this, and password managers do not expose the option.

HideMyShare sets the exclusion flag on the password manager's behalf. Add Bitwarden, 1Password, KeePass, LastPass, or any other window — and it disappears from the shared stream. Not blurred: gone. You open the vault, copy the credential, paste it, and everyone else just never sees the window.

Step by step (about 30 seconds)

1. Install HideMyShare before the call (Windows 10 version 2004 or later, Windows 11 supported).
2. Open your password manager and add its window in HideMyShare — or let auto-protect pick it up.
3. Share your screen as usual, and open the vault whenever you need it.

Windows you open later are detected and re-protected automatically within about a second, so a login popup or a second vault window cannot slip through.

What viewers see

Nothing. The shared desktop looks normal without that window — windows behind it take up the space, and nothing marks the spot. No one can tell a window is hidden.

FAQ

Can I still copy passwords while the vault is hidden? Yes. The window stays fully interactive on your screen; only the shared stream excludes it.

Does it protect every password manager? Any window you add is protected. Bitwarden, 1Password, KeePass, LastPass, Chrome's built-in manager — all of them are ordinary windows and all work the same way.

What about the browser tab I unlock my vault in? You can protect the browser window (or tab) too. If the vault lives in a browser, add that window in HideMyShare and it stays out of the capture as well.

Will the meeting app warn anyone that something is hidden? No. The shared view is a normal desktop without that window; nothing marks the spot.

Does it work with OBS or game streaming? Yes. Any app that captures the screen honors the exclusion flag — meeting apps, streaming tools, and recording software alike.

Is HideMyShare itself a security risk? It runs fully offline with no account and zero telemetry. It hides windows you choose, nothing more.
