Mifos-Passcode-CMP

Mifos-Passcode-CMP is a secure and flexible passcode management library built using Kotlin Multiplatform and Jetpack Compose Multiplatform (CMP). It enables developers to easily integrate passcode-based authentication along with biometric authentication (such as fingerprint or face recognition) into cross-platform applications using a shared codebase.

Designed with modularity and security in mind, this library is a foundational part of the Mifos mobile ecosystem and is suitable for any Kotlin Multiplatform project where secure access control is required.

sample

Cross-platform sample implementation of the passcode screen UI:

• commonMain/ – Shared passcode screen logic using Compose Multiplatform.
• <platform>Main/ – Platform-specific UI wiring for the passcode screen.

For a basic implementation of the PassCode Screen

• Import PasscodeScreen to your project which has 4 parameters mentioned below:
  • onForgotButton: This will allow to handle the case when the user isn't able to log into the app. In our project we are redirecting the user to login page
  • onSkipButton: This offers users the flexibility to bypass the passcode setup process, granting them immediate access to the desired screen
  • onPasscodeConfirm: This allows you to pass a function that accepts a string parameter
  • onPasscodeRejected: This can be used to handle the event when user has entered a wrong passcode
