Printed codes for Google

Did you know that there's another way to log into Google when you get the 2-factor authentication request and you don't have your phone or USB drive with you?

You can print a set of codes and keep them with you in your wallet, lanyard, etc.  This has bailed me out more than once when I've left my phone somewhere and have needed to log into a new computer.

Here's how, from Google Support:

Create and view a set of backup codes

1. Go to the 2-Step Verification section of your Google Account.
2. Under "Backup codes," select Setup or Show codes.You can print or download your codes.

If you think you backup codes were stolen or if you're running out, select Get new codes. Your old set of backup codes will automatically become inactive.
