What is Two-Factor Authentication (2FA)?

Two-factor authentication (or 2FA) is an extra layer of security used to make sure that people trying to gain access to an online account are who they say they are.

It uses a two-step verification process. First, a user will enter their user name and a password. Second, instead of immediately gaining access, they will be required to provide another piece of information.

In this case, we use an app such as Google Authenticator which provides a single-use time-based code. You simply install the app onto your phone and scan the QR code to set up the two-factor authentication, and then every time you need to log into your Passle account, after entering your email address and password, you will be prompted to enter the code from the app. This means that in order to access your account, you will need your phone to hand. This makes your account considerably more secure than relying only on email and password to log in.

There are a selection of different apps that can be used for 2FA. We recommend using Google Authenticator for the optimal experience with Passle, but you will find most other 2FA apps will work as well.

You can find Google Authenticator in the Play Store for Android devices, or iTunes for iOS devices.
