My personal account is where I do my own browsing, where I sign in with my personal services, and where I save my favorite sites. And the reason is that anyone using multiple accounts for different purposes has likely siloed their Chrome information into each one for those specific purposes. The latter is the most problematic, in my opinion. There are outliers, though, like Google Duo and Chrome. The account switch gesture works in Gmail and many other Google apps. Even better, they all let you swipe up or down to instantly move between accounts - a gesture that started showing up in 2019 and has since spread to most Google apps. You're signed into all of them at the same time, and a simple tap on your avatar in the top right lets you select the account you want. Most of these offer a quick account switch where you don't need to log out of one to log in with another. Of the 30+ Google apps installed on my phone, some don't have to be logged in to an account (like Calculator, Clock, Files, or Lens), but there are many that do. And that is currently the bane of my existence. In general, it's relatively easy to reconcile the data from these accounts, or at least it's simple and fast enough to switch between them. Either because one of them is personal and the other for work, or for a myriad other reasons. I, however, and many like me, have to use multiple accounts. It must be nice to have one place for all emails, contacts, app purchases, calendars, bookmarks, and every other facet of your digital life. Those of you with a single Google account have it easy.
