A site allowed to use your camera or microphone can request them while you are on that site. A past meeting or support session may leave a remembered permission that is no longer needed. Chrome lets you review allowed and blocked origins separately for Camera and Microphone, and some prompts offer one-time access. Removing one site's exception is more precise than disabling all cameras at the operating-system level.
Before you start
Identify the exact website you trust for upcoming calls and any old origins you no longer use. Do not use a call link from an unexpected message to test permissions. Have a harmless test call or device preview ready, and know that a work or school administrator may control some settings. Check whether a separate desktop app, not Chrome, is using the sensor.Do it step by step
- From Chrome's menu, select Settings, then find Camera under Privacy and security, Site settings. Review the allowed and blocked website lists, looking for old meeting services and unexpected spellings.
- Remove permission for an obsolete or suspicious origin. Repeat under Microphone; changing one sensor does not necessarily change the other.
- For a trusted meeting site, decide whether Allow this time or Allow while visiting better matches your needs when Chrome asks again. Avoid blanket permission for unrelated sites.
- Open the legitimate meeting site's device preview and confirm the chosen camera and microphone. If it cannot connect, inspect the site's Chrome permission before changing every system privacy control.
- Check the operating-system camera and microphone privacy settings if Chrome cannot reach the hardware. Select the correct input devices in Chrome and the meeting service, and check the headset's physical mute switch.
- After the call, revisit Site settings and remove the exception if it was temporary work. Note the trusted origin so a lookalike domain cannot be justified as a normal permission later.
