When we launched Chrome four years ago, most people accessed the web through a personal computer. Our goal was to help build a better web--a web that is faster, simpler and more secure.

Fast forward to today, and many people have more than one device--a smartphone, a tablet, a computer at work, a computer at home. The beauty of the web is that it’s the one platform that can deliver a consistent experience on any device with a browser. We've been working to build a more seamless Chrome experience that lets you to take your Chrome stuff with you on all your devices.

The web isn’t the same for everyone--we all have our own individual bookmarks, tabs, history, passwords and more that reflect what we do online and what we care about. Chrome now enables you to access your web, everywhere. Whether you’re on a Windows, Mac, or Linux computer, a Chromebook, or an Android or iOS smartphone or tablet, you can have the same consistent experience no matter where you go, just by signing in to Chrome.

As you use Chrome on more devices, we remain focused on providing you with the most secure web experience possible. Building on four years of security work, recent improvements such as more robust plug-in sandboxing and Safe Browsing for downloads ensure that your browsing is more secure than ever before.

To track Chrome’s journey from a better web to your web, we created a Chrome Time Machine (of sorts) that lets you travel through key moments in Chrome’s history over the past four years. You may even uncover a special birthday gift from the Chrome team, if you find the hidden clue and type in the secret code...

Thank you all for being a part of Chrome, and for bringing your own personal touch to the web. On our fourth birthday, we’re looking forward to many more amazing years of helping you do more online. Happy browsing!
