Is It Safe to Share Your Screen With Tech Support?

Start with one question: who contacted whom?

The strongest signal is who made first contact. Microsoft says it will not call you about a problem with your computer unless you reached out first. Apple says to hang up on unsolicited calls that claim to be from Apple Support. The FTC gives the same advice for any unexpected call about computer problems.

So if you called a number from the official website or opened a ticket yourself, the session is probably real. If someone called you, messaged you, or a pop-up told you to call a number, treat it as a scam until proven otherwise. Hang up and contact the company yourself through its website or app.

• Real Microsoft error messages never include a phone number to call.
• Caller ID can be faked, so a familiar company name proves nothing.
• No real support team asks for payment in gift cards or crypto.

Know the difference between viewing and control

A screen share lets someone watch. Remote control lets them move your mouse, type, open files, and install software. These are very different levels of trust, and many tools let you choose.

Microsoft Quick Assist is a good example. The person sharing picks either View screen or Take full control, and a helper in a view-only session has to ask before taking control. Start with view only. Most problems can be diagnosed by watching while you click. Allow control only when you started the session through official support and the fix really needs it.

Some remote tools can also stay installed and reconnect later without asking. If a helper asks to set up unattended access, ask why, and make sure you know how to remove it.

Company IT is a special case

At work, your IT team may already have a remote support tool installed on your laptop. That is normal, and it often means they can connect faster than outside support. It also means a message that only says "IT here, accept this request" deserves a quick check.

Confirm through a channel you already know. Reply to your open ticket, call the helpdesk number on the intranet, or message a colleague on the IT team you have worked with before. Attackers sometimes pose as internal IT in chat or by phone, because people trust it.

Your company laptop also holds work data you may not want a helpdesk agent to browse, like HR documents or customer exports. The same rules apply: share the app with the problem, close the rest, and watch the session.

Close these before the session starts

Even a real support agent does not need to see your inbox or your bank balance. Take two minutes before you share to clean up. If the tool lets you share one window, share only the app with the problem.

• Password manager windows and browser autofill popups.
• Email, chat, and messaging apps that show previews.
• Online banking, payment, and shopping tabs.
• Personal documents, photos, and desktop files.
• Two-factor apps and any page showing recovery codes.
• Notifications: turn on Do Not Disturb or Focus for the session.

Ask these questions before you share

A real support agent will not mind a few questions. A scammer often will, because questions slow them down. Ask before you install anything or click Share.

Write the answers down, or at least note the ticket number. If anything feels off later, you have something to check against when you contact the company again through its official site.

• What is my ticket or case number?
• Which tool are we using, and where do I download it from?
• Do you need to see my screen, or control it?
• Which app or window do you need to see?
• Will the tool stay installed after we finish?
• How do I end the session myself?

Stay in charge during the session

Watch the screen the whole time. If the agent opens something unrelated to your problem, ask why. You can stop sharing at any moment and restart once you understand the reason.

Never type a password while someone is watching or controlling the screen. If you need to sign in, pause the share or turn off control, sign in, then resume. Do not read out one-time codes. A real agent does not need them.

If the problem lives in a web dashboard that shows customer names, account numbers, or personal details, blur those fields before you share. Safe Screen Share can blur parts of a web page in place, so the agent sees the layout and the error without the private data.

• Stop if they ask you to open online banking or a payment app.
• Stop if they ask you to install a second remote tool.
• Stop if they push urgency, threats, or a refund you did not expect.

End the session and remove access

When the fix is done, end the session in the support tool itself, not just by closing a window. Then check that nothing stays behind.

• Stop sharing or end the call in the support tool.
• Uninstall any remote access app you installed for this session.
• Check for apps that start at login or allow unattended access.
• Sign out of accounts the agent saw you open, if they were sensitive.
• Change any password that was visible on screen.

If you think it was a scam

Disconnect from the internet and end the session right away. Uninstall anything the caller asked you to install. Change passwords for email, banking, and any account they saw, starting with email because it can reset the rest. Call your bank using the number on your card if they saw payment details or you paid anything.

Report it. In the US, report scams to the FTC at ReportFraud.ftc.gov. Microsoft also takes reports of tech support scams, even when the caller did not claim to be from Microsoft. Our guide on what to do after a screen sharing scam has a full checklist.
