Introduction to Cyber Security

Step 3: At the top of the page, you will see a list of sites, applications and devices to which you have granted some level of access to your account. If you allowed a third-party website (e.g., LinkedIn, Twitter, Foursquare) to comb your Gmail Contacts to find friends, for example, you will see that listed. If you use other Google applications, you will also see those listed. Feel free to revoke access to any site or program you no longer wish to use.

Step 4: Scroll down to the field at the bottom for entering the name of a device. Enter in something that will help you remember what this application-specific password is for -- e.g., Mail App on iPhone, Google App on iPhone, Chrome Sync, Outlook, Thunderbird, or whatever describes your application. Click "Generate password". You should generate a new application-specific password for each application.

Step 5: Open up the application. Go to the settings page where you enter in your Google Account information. Type in your Google account name as usual. Now instead of your account password, type in the application-specific password in the password field. You have now granted this application full access to your Google account. You will only need to enter this password once. There is no need to write it down or memorize it, and it will not be displayed by Google again.

Step 6: Click "Done" on your web browser once you have successfully entered the application-specific password.

Step 7: Know how to revoke an app's access to your Gmail account. If you don't want to use an app anymore, or you lost your phone and want to stop anyone who has it from accessing your Gmail, simply click on the "Revoke" button in your application-specific password settings page.
