Introduction to Cyber Security

Step 8: Create new application-specific passwords for each application that you connect your Google Account to! This means if you sync your Google Account to two mail apps and a chat client, you should have three application-specific passwords.

Method 2 of 2: If You Lose Your Phone

If you lose your phone and have 2-step verification turned on, you can still access your Gmail account. You also can and should follow these steps to stop strangers from gaining access to your Google accounts.

Step 1: Revoke your current application-specific passwords. If you have a smartphone with apps linked to your Google account, they will automatically be signed out. When you get a new phone, you can generate new application-specific passwords (see previous section) and enter them into your new devices.
Step 2: Change your Gmail password. Even if someone else has your verification code, they can't get into your Gmail account without your new password. While it's unlikely that the person who has your phone also has cracked your Gmail password, you can never be too sure. If you are logged into Google from any web browser on your mobile device, you'll now also automatically be signed out.
Step 3: Add a backup phone number if you have a second mobile device. Go to your2-step verification settings page and click "Add a phone number" in the "Backup phones" section.
Step 4: If you don't have a backup phone, use your list of printable backup codes to access your account. On your 2-step verification settings page, click "Show backup codes". If you haven't done so already, print out this page and keep it in a safe but accessible place -- such as your wallet.
Step 5: If you get phone and change your phone number, be sure to revoke access to your previous number on the 2-step verification settings page.
