Latest Google Chrome update lets you turn off auto-sign in
The feature was introduced in Chrome 69 but was quickly panned for being more annoying than useful. Auto sign-in happens when, for example, you log into your Gmail on Chrome and the browser automatically links with your Google Account.
The new update allows users to disable the feature in Settings, though it remains ON by default. Chrome 70 will also show you messages, letting you know whether you're signed into the browser itself, syncing your account and linking previous activities, or whether you're just logged into a Google service like Gmail, Drive, or Photos.
