In a move that should actually make everyone happy, Google is now allowing you to stay logged into multiple Google accounts at the same time. According to the announcement posted to Google+, the change will enable you to manage AdWords accounts without having to log in and log out multiple times.
The new system is easy peasy; all you have to do to enable multiple account logins is to click on your Customer ID or login email (located in the top right corner of the screen). From there, you have an option to “Add Account.” Just like in Gmail.
This is likely to be a huge time saver, especially since normally logging in and out of accounts involves having to start from scratch with each time you change accounts.
I tend to get distracted incredibly easily, so by the time I’ve got a new account open, I have no idea what I was going to do with it.
That said, you may want to be careful when you start using this new feature; it might be easy to start making account wide changes without realizing you’re in the wrong account since you don’t have to go through a process to toggle through them.
