MeetAccountChecker is a free Chrome extension developed by ssvaluesccg. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools subcategory. This extension is designed to prevent accidental sign-ins to GoogleMeet with unintended accounts.

1. Account Verification: Before entering GoogleMeet, MeetAccountChecker compares the logged-in account with the domain that the user has registered in advance. If the domain does not match, a pop-up notification prompts the user to change the account. If the domain matches, no notification is displayed.

2. Customizable Domain Detection: Users can input and register the domains they want to detect by clicking on the extension's icon. They can also modify the registered domains at any time.

With MeetAccountChecker, users can ensure that they are using the correct Google account before joining a GoogleMeet session, avoiding any potential confusion or privacy concerns.
