Yes, access to your Google Analytics account can be taken just as easily as it is given. Whether you accidentally gave access to someone or need to kick a user off, it can be done in a couple of minutes from the same platform that you were just on. Go back to the admin settings of your account, and then to the property user management tab. Once you are there, click the three-dot line on the right side, and hit “remove access”. After you do so, a popup will appear, asking you to verify the decision, to which you will accept. The process is quick, discreet, and does not even send a notification.
