How many times has this happened to you? Someone sends you a link to access a shared Google file. You click on it, but you get a message saying your account does not have permission to access the file. This happens a lot when a user is logged into more than one Google account in a single browser window. For instance, there’s the work Google account, the personal, the family member’s account, etc. Only one of those accounts provides access to the file shared by a work colleague. And there’s no way your browser will know which Google account you want to use at any given moment.
The solution is to create a separate Google Chrome Profile, so that you can switch between Google accounts as needed. Perhaps you can create a Work profile and assign your work email to it. Do your professional work in this browser. And then create a Home profile and assign your personal email to it. Do your personal stuff in this browser. And so forth.
By keeping your Google accounts logged in on separate Chrome browser windows, you’ll be able to easily switch back and forth between accounts and avoid any confusion regarding file access. Check out this tutorial to help you set up your multiple Chrome Profiles.
