How to Hide Your Bank Details When Screen Sharing Online Banking

To hide your bank details when screen sharing online banking, blur your account and routing numbers, balances, transaction history and card numbers directly in the page before you present — BlurFirst paints the blur in as real pixels, so it survives Zoom, Google Meet, Microsoft Teams, Loom and any recorder. But the more important answer comes first: you should almost never screen-share your online banking with someone you don't personally know and trust. Blurring is for the legitimate cases — showing your bookkeeper a statement, walking your accountant through one transaction, or reviewing finances with a partner or advisor you already work with.

This guide stays generic on purpose. Every bank's dashboard looks a little different, but the sensitive elements are the same everywhere, and so is the approach: hide the numbers in the page, share a single tab, and keep a panic shortcut ready.

First, the safety rule: never share your banking screen with a stranger

Anyone who contacts you out of the blue and wants to watch your online banking — a "refund" call, "tech support", a "bank fraud department", a "government" agent — is almost certainly running a scam. Real banks and agencies do not need to watch your screen while you're logged into your account. If someone on a call directs you to share your banking screen, or to install screen-sharing software so they can "help", stop and hang up. Blurring does not make that situation safe; the only safe move is not to share at all.

What's sensitive in online banking

Whatever your bank's layout, these are the things you don't want a viewer — or a recording — to keep:

• Account and routing numbers — the full account number, the routing / sort code, and any IBAN, usually shown on the account details or "receive money" screen.
• Balances — available and current balances, and the totals across every account when they're listed together on the overview.
• Transaction history — the statement of recent activity, naming payees and merchants alongside the amounts and dates, which paints a detailed picture of your life.
• Card numbers — debit and credit card numbers and their last-4, plus expiry, on the cards screen.
• Your name and mailing address — shown in the header, on statements and on the profile / settings pages.
• Statements and downloads — PDF statements and exported files that bundle all of the above into one document.

How to blur your online banking before you share

Once you've decided sharing is appropriate, the flow with BlurFirst is quick:

1. 1

   Share one browser tab, not your screen

   Present only the tab with your banking site open. Keep email, other tabs and any other windows out of the feed entirely.

2. 2

   Start BlurFirst

   Open the page you'll show and press Ctrl/⌘ ⇧ Y to bring up the control bar.

3. 3

   Box-blur the balances and the transaction table

   Drag a rectangle over the balance figures and over the whole transaction list. The region stays anchored as you scroll a long statement.

4. 4

   Element-blur the account and card numbers

   Click the account number, routing number or a card field to frost just that value while the rest of the page stays readable. Click again to reveal only when you truly need to.

5. 5

   Scan for card numbers and PII (Pro)

   One local Scan finds and blurs card numbers, emails, phone numbers and SSNs on the page. Pair it with a box blur for account/routing numbers and payee names, which are free text.

6. 6

   Keep the panic shortcut ready

   If you land on the wrong screen — say, full account details — press Ctrl/⌘ ⇧ H to blur the whole page instantly.

Blur instead of over-sharing

When sharing is legitimate, the goal is to show the minimum. Your bookkeeper may only need to confirm that one payment cleared; your accountant may need to see a single transaction's date and amount, not your balance or every other payee. Blurring lets you reveal exactly that one row while your account numbers, balance and the rest of your history stay frosted. It's the same principle a good professional already follows — show what the task requires and nothing more.

One honest limitation

BlurFirst only affects content inside a browser tab, so it works on online banking in a browser — not your bank's mobile app, which is native. If you normally bank on your phone, log into the website in a desktop browser to present. It also can't blur other windows or your desktop, which is why you should share a single tab. Scan detects patterns (card numbers, SSNs, emails, phone numbers), not free-text names or account numbers — cover those with box or element blur. A desktop app is in development.
