In Pictures: 10 great Google tools you need in your business workflow

Two-step verification for Google accounts

If news about hackers gaining access to password-protected data has made you nervous (or even if it hasn't), consider beefing up your Google account security by activating Google's two-step verification for account logins. This adds a second password (in addition to the usual password entry) for logins: a code Google sends to your cell phone or landline, or that you store on paper in your wallet (in case you're not near a phone). After an initial setup, you can waive the requirement on trusted computers and mobile devices for 30 days—and you can always revoke waivers from your security settings.
