2-factor authentication provides straightforward identification and authentication of users by means of coupling ”something you know” (a password) with “something you have” (a mobile device). The SSO/MobileKey app is a powerful Time-based One-Time Password (TOTP) generator that follows the RFC-6238 standard, which is used by Google Authenticator, Amazon AWS, and others. It allows you to easily manage and synchronize your authentication tokens across multiple devices, and backup to Dropbox and iCloud, access via TouchID, and organize them into folders.
