diese App is a simple authenticator app that works with 2-Step Verification to help you better protect your internet accounts. 2-Step Verification is an advanced security feature that makes it harder for someone to break into your internet accounts (Google, Facebook, Microsoft, Dropbox etc... ).  You will never need a network connection to generate or use codes. diese App doesn't share nor records any personal data, and it never connects to the Internet.  It also adds an extra security layer with Touch ID and Face ID on compatible devices, so you can protect your codes even better. - Encrypted iTunes backups will save your codes so you can get them back if you switch devices.  It will require both your password and a verification code you can generate with this app.
