This Plugin enables you to add a classical Pattern Lock to your app similar to the lock screen of an Android Smartphone. You can use the Pattern Lock to add an additional layer of user authentication (such as 2FA) and to increase the user experience on smartphones. The correct code that unlocks the Pattern Lock ist stored as a number, where ich number represents the position of a dot in accordance with a normal phone dial. You can also modify the background colour of the Pattern Lock. You can store the pattern for each user as a number within your database assigned to each user, and then check upon login for this code.
