What to Do If a QR Code Asked to Share Your Screen
A QR code can open a support page, meeting room, chat, or app that asks you to share your screen. The QR code itself does not need to control your device to create risk. The danger is showing passwords, one-time codes, banking pages, documents, or private messages to someone you have not verified.
If you have not approved screen sharing
- Close the page or meeting if you were not expecting support.
- Contact the company, school, bank, or help desk through a known channel.
- Do not share your screen to prove identity, unlock an account, or receive a refund.
- Do not read out verification codes, backup codes, or passwords from your screen.
This overlaps with tech support QR code scams and remote access QR code risks.
If you already shared your screen
- Stop sharing: end the meeting, support chat, or app session.
- List what was visible: accounts, balances, documents, codes, messages, or saved passwords.
- Change exposed passwords: use the real service, not links from the QR page.
- Review sessions: remove unknown devices, connected apps, and active logins.
- Contact providers: call your bank, employer, school, or account provider if sensitive screens were shown.

Frequently asked questions
Can a QR code make me share my screen?
A QR code can open a support page, app, or meeting link that asks for screen sharing, but you still have to approve the sharing prompt. Do not approve it unless you trust the destination and support channel.
What if I shared my screen after scanning?
Stop sharing, close the session, list what was visible, change exposed passwords from official sites, review account activity, and contact your bank or provider if payment or account screens were shown.
Is screen sharing the same as remote access?
No. Screen sharing may only show your screen, while remote access may let someone control it. Both can expose passwords, verification codes, banking pages, documents, and private messages.
