Google Authenticator is a software token that implements two-step verification services. Authenticator provides a six- to eight-digit one-time password which users must provide in addition to their username and password to log into Google services or other sites. Typically, a user installs Google Authenticator app on a smartphone. To log into a site or service that uses two-factor authentication, the user provides user name and password to the site and runs the Authenticator app. The app displays an additional six-digit one-time password. The same password is independently generated by the site, which asks the user for it. The user enters it, thus authenticating the user's identity
For this to work, a set-up operation has to be performed ahead of time: the site provides a shared secret key to the user over a secure channel, to be stored in the Authenticator app. This secret key will be used for all future logins to the site.
With this kind of two-factor authentication, mere knowledge of username and password is not sufficient to break into a user's account. The attacker also needs knowledge of the shared secret key or physical access to the device running the Authenticator app. An alternative route of attack is a man-in-the-middle attack: if the computer used for the login process is compromised by a trojan, then username, password and one-time password can be captured by the trojan, which can then initiate its own login session to the site or monitor and modify the communication between user and site.
For Google Translator to work on your Smartphone, go to the AppStore and download and install Google Translator. During your Embleema registration, you will be required to scan a QR code using Google Authenticator. If the Authenticator app cannot locate a barcode scanner app on your mobile device, you might be prompted to download and install one. If you want to install a barcode scanner app so you can complete the setup process, select Install, then go through the installation process. Once the app is installed, reopen Google Authenticator, then point your camera at the QR code on your computer screen. For subsequent logins, Embleema will ask you to type in a passcode generated by Google Authenticator for your Embleema login.
