When you sign in to Chrome with your Google Account, you can take advantage of several time-saving services:
Sync lets you access your Chrome bookmarks, browsing history, and open tabs from other devices where you’re also signed in.
Chrome to Mobile lets you send webpages from your computer to your mobile device with one click.
Auto sign-in helps you sign in to Google services with a touch of a button. No need to type your username and password.
To sign in, open Chrome and tap (or press) the Menu Key > Settings > SIGN IN TO CHROME (at the bottom of the screen).
