ionic-4-fingerprint-lock

If your app contains sensitive data, most of the time you want to lock the application as soon as the user becomes inactive or switches to a different app.

In this Quick Win we will implement a login mechanism using the Fingerprint All-in-one plugin which allows to use both fingerprint and also Face ID on iOS!

We will also use a login page as a regular page and modal, and automatically display it once the app goes to the background.

The full quick win with snippets is only available to Ionic Academy members.
