Chrome asks for permission the first time you use your microphone

When you visit a website that wants to use your microphone — for a video call, voice message, or voice search — Chrome shows a permission prompt at the top of the page. You'll see a small popup asking "Allow [website] to access your microphone?" with options to Allow or Block. Click Allow, and the site can use your microphone for that session.

If you click Block, the site won't be able to access your microphone. You can change your mind later by adjusting Chrome's settings, which is useful if you blocked a site by accident or want to revoke access to a site you no longer trust.

The permission prompt appears once per site, per browser profile. If you use Chrome on multiple devices or in multiple user profiles on the same device, you'll see the prompt separately on each one.

Key Takeaways

  • Chrome shows a permission prompt the first time a website requests microphone access, and you choose Allow or Block right there.
  • You can change microphone permissions for any site at any time by going to Chrome Settings > Privacy and Security > Site Settings > Microphone.
  • Blocking a site prevents it from accessing your microphone; allowing it only grants access while you're on that site.
  • If you don't see a permission prompt, check whether Chrome itself has microphone access enabled in your operating system settings.

Allow microphone access for a specific website

The easiest way is to respond to the prompt when it appears. When a website requests microphone access, look for the permission popup at the top of the Chrome window — it usually appears as a small bar or dropdown. Click the Allow button, and Chrome grants that site access to your microphone for the current session.

If you accidentally clicked Block, or if the prompt has disappeared, you can grant access through Chrome's settings instead. Click the three-dot menu in the top right corner of Chrome, then go to Settings. Select Privacy and Security on the left, then Site Settings. Scroll down and click Microphone. Find the website in the list under "Allow" or "Block" and move it to the Allow section if needed.

Check whether Chrome has microphone permission on your device

Before Chrome can give a website access to your microphone, your operating system must allow Chrome to use the microphone in the first place. If websites keep saying your microphone isn't working, the problem might be at the OS level, not in Chrome.

On Windows: Go to Settings > Privacy & Security > Microphone. Make sure the toggle for "Microphone access" is on. Then scroll down to "Allow apps to access your microphone" and confirm that Google Chrome is switched on.

On Mac: Go to System Settings > Privacy & Security > Microphone. Look for Google Chrome in the list and make sure it has a checkmark next to it. If Chrome isn't listed, it means no app has requested microphone access yet.

On Linux: Microphone permissions are usually handled by your desktop environment or audio system rather than a central settings panel. If Chrome can't access your microphone, check the documentation for your specific Linux distribution.

Manage microphone access for all websites at once

If you want to block microphone access across all sites by default, you can change Chrome's default setting. Open Chrome Settings, go to Privacy and Security > Site Settings > Microphone, and select "Block (recommended)" at the top. From then on, websites will not be able to access your microphone unless you explicitly allow them one at a time.

You can also set Chrome to ask you every time a site requests microphone access, which is the default behavior. This gives you the most control — you decide for each site whether to grant or deny access.

Remove microphone access from a website you no longer trust

If you previously allowed a website to use your microphone and now want to revoke that permission, go to Chrome Settings > Privacy and Security > Site Settings > Microphone. Under the "Allow" section, find the website and click the three-dot menu next to it, then select Remove. The site will no longer have access to your microphone, and Chrome will show the permission prompt again the next time that site requests it.

Removing a site from the Allow list doesn't delete your browsing history or other data on that site — it only removes the microphone permission. If you want to clear all data associated with a website, you'll need to use Chrome's Clear Browsing Data tool separately.

Troubleshoot when a website says your microphone isn't working

If a website says it can't detect your microphone even though you allowed access, start by checking that your microphone hardware is actually connected and working. Unplug and replug USB microphones, or restart your device if you're using a built-in microphone.

Next, verify that Chrome has microphone access in your operating system settings (see the section above). Then go back to Chrome Settings > Privacy and Security > Site Settings > Microphone and confirm the website is in the Allow list. If it's in the Block list by mistake, move it to Allow.

If the website still can't access your microphone, try clearing Chrome's cache for that site. Go to Settings > Privacy and Security > Clear Browsing Data, set the time range to "All time," check "Cookies and other site data," and click Clear Data. Then reload the website and allow microphone access again when prompted.

Frequently Asked Questions

Can a website access my microphone without my permission?

No. Chrome requires explicit permission before any website can access your microphone. The site cannot use your microphone in the background or without you seeing and responding to the permission prompt. If you're concerned about a particular site, you can always block it in Chrome settings.

What's the difference between allowing a website and allowing Chrome in my OS settings?

Your operating system controls whether Chrome itself can access the microphone. Chrome's site settings control which websites Chrome allows to use the microphone. Both must be enabled: your OS must allow Chrome to use the microphone, and Chrome must allow the specific website.

If I allow a website to use my microphone, does it stay allowed forever?

The permission stays in effect until you remove it. You can revoke access at any time by going to Chrome Settings > Site Settings > Microphone, finding the website, and clicking Remove. The next time that site requests microphone access, you'll see the permission prompt again.

Can I allow microphone access only for video calls and block it for everything else?

Chrome doesn't let you set different rules based on what a website is doing with the microphone. You allow or block the entire site. If you trust a site for video calls but not for other uses, you'll need to monitor what it's doing or use a different browser profile for that site.
