**Pro**: easily keep track of login attempts for your user profile, and view the two-factor code directly in the notification on your smartphone.
**Con**: uses a text message each time, which may be limited on some cell phone plans.
Google Authenticator requires some additional setup before it can be used. First you will need to download the Google Authenticator app for your smartphone, and you may need to download a QR Code scanner as well.
