Yes, you can enable two-factor authentication in your profile making your AwardWallet profile much more secure. At a high level it means you will use your phone (or an app of your choice, such as 1Password or LastPass) to generate a one-time code in addition to your username and password to login to AwardWallet.  If you don’t know what two-factor authentication is you can read the following Wiki article or just Google it.
Setting up two-factor authentication is very easy; first, you need to download a Google Authenticator app (or similar), for your Android, iOS or Windows Phone device. Alternatively, you can use a password management tool such as 1Password to generate these one-time codes. Then you need to click “Setup” under the Two-factor Authentication heading in your AwardWallet profile. After that you will see a special QR code that needs to be scanned by the Google Authenticator app (or by the password management app) to set it up:
Then you enter the code generated by the app into AwardWallet and you are done. For more details please check out this tip:
