So, what exactly does Google Authenticator do? Essentially, it generates a unique code that you need to enter in addition to your password when logging in to your account. This code changes every 30 seconds, making it virtually impossible for hackers to guess or phish.
One of the things I love about Google Authenticator is how seamless it is to use. Once you've set it up, you'll get a push notification on your phone or desktop (yes, there is a desktop version - more on that in a bit!) with the code, and you just enter it to log in. It's so easy, you'll wonder how you ever managed without it!
