To get around this obstacle, you can open two windows in your browser–one in normal mode, one in incognito mode–and sign in to access your different Gmail accounts at the same time. This might be inconvenient if someone maintains multiple Gmail accounts for personal use and work activities.
Many web services such as Google allow you to sign into only one registered account at a time. Browsing online via incognito mode will help protect your privacy by not storing any of these types of information. You don’t want the browser to save any of your passwords, and you also don’t want it to store any of your browsing history so that someone could come across the login page for your personal website. Sometimes you might need to log into one of your web accounts from a computer at a library, cafe, or other public place. There are plenty of practical, less potentially embarrassing reasons why you would want to use incognito mode. But that couldn’t be further from the truth.
