Google’s two-step verification process is an extra security measure to protect your Google account from being compromised. This free option confirms that you’re you before granting access to your Google apps, such as Gmail.

The problem with a regular authentication model -- such as a username and password -- is that it can be more easily hacked. Even if you use strong passwords and security software for your computer, there are many instances of data breaches, even among high-profile companies. So you never know when, how or where an attacker can strike. Plus, if you use the same password for all your various online accounts, it leaves your entire digital life vulnerable.

Google’s two-step verification process addresses this issue head-on: In addition to a standard username and password, you’ll also need a code that’s sent via SMS (text message) to your mobile phone. Before you gain access to the Google app, you’ll be prompted to enter that short verification code, which you’ll get from your mobile phone. If you don’t like using a text message, you can also download and install the Google Authenticator app on your Android, BlackBerry or iOS device (such as an iPhone, iPod Touch or iPad).

To get started, log in to your Google account, go to your “Accounts” settings page and look for the “Using two-step verification” link. Click it and start the setup process. You’ll also be prompted to enter a backup phone number -- be it a landline or secondary mobile number -- in case you lose access to your primary phone.
