Google today is adding support for multiple account sign-ins, so anyone with more than one Google account can just log into one, but quickly switch between accounts without special add-ons or other tricks.
We mentioned it might happen yesterday, but it looks like the new feature is rolling out for real, starting today. The feature won't be enabled for everyone just yet, but when it is, you should be able to set it up here. Alternately, Google Operating System points out that you may also see a link to multiple sign-in setup on your Google Accounts page. (It's starting to roll out today, and if it's like most Google rollouts, you should see it within at least a few days.) What you need to know:
- You can sign into a maximum of three accounts at once.
- The first account you sign in with when you're setting up multiple sign-in will be set to your default account
- You can't use Offline Gmail or Calendar with the multiple sign-in feature.
- Multiple sign-ins only work with these Google apps — that is, Google App Engine, Code, Calendar, Gmail, Reader, Sites and Voice support the multiple sign-in feature. Most notably, Google Docs isn't yet supported, but it's marked as coming soon.
Unofficial Google blog Google Operating System also notes that multiple sign-ins aren't supported on mobile devices and that the GCal gadget doesn't work with it (yet, at least). We're not seeing it in our accounts yet, but if you have better luck, let's hear how it works for you in the comments.
