What is it?2-step validation for Login adds a layer of protection for you and your devices by generating random codes for login. You can set up random validation codes for all of your Google-related apps and devices. I've got them for laptop access to web-based apps such as Seesmic and Twitter.com, as well as my Droid phone apps. Can never be too secure...
Why bother?Because right now someone could be hacking your account.
Because if you lose your phone tomorrow, they won't need to. (You're probably already logged into every possible Google app on your smartphone, aren't you?)
How do I set it up?I recommend reading this article by Tech Crunch or this one by Internet's Best Secrets for more information. Or check out the announcement on the Google Blog.
- Log into Google
- Go to your account page.
- On your account page, check the Security options for "Using 2-step verification".
- Select "Turn on 2-step verification".
- Set up how to receive verification codes (by mobile app, phone, printables)*
- Set up a backup phone number to receive codes
- Set up codes for specific applications
If you get a little confused, be patient and work through it or check the Verification Help info. It took me a few tries to get the right password for each app and device, but once it was set up, all was good.
So go ahead. Go protect your devices. There'll be plenty of geek for you when you get back.
