Open Source, Native, Cross-Platform 2FA App for Watch, Mobile, Desktop, Web, CLI 4 | 5 | [![Kotlin](https://img.shields.io/badge/kotlin-2.2.0-blue.svg?logo=kotlin)](https://kotlinlang.org/) 6 | [![Compose Multiplatform](https://img.shields.io/badge/compose-multiplatform-blue.svg?logo=jetbrains)](https://github.com/JetBrains/compose-multiplatform) 7 | 8 | ## ROADMAP 9 | 10 | - [ ] Common functionality 11 | - [x] Add new accounts 12 | - [x] Display accounts with 2FA codes 13 | - [x] Save accounts to a storage 14 | - [ ] Backup & Restore via a backup transport 15 | - [ ] Export & Import accounts (encrypted with passkey) 16 | - [ ] Import from other 2FA apps 17 | - [ ] Authy 18 | - [ ] 2FAS 19 | - [ ] Ente 20 | - [ ] Mobile App 21 | - [ ] Desktop App 22 | - [ ] Web Extension 23 | - [ ] CLI App 24 | - [ ] Add new accounts 25 | - [x] Display 2FA codes with auto-refresh 26 | 27 | ## CODE STRUCTURE 28 | This is a Kotlin Multiplatform project targeting Android, iOS, Web, Desktop. 29 | 30 | * `/composeApp` is for code that will be shared across your Compose Multiplatform applications. 31 | It contains several subfolders: 32 | - `commonMain` is for code that’s common for all targets. 33 | - Other folders are for Kotlin code that will be compiled for only the platform indicated in the folder name. 34 | For example, if you want to use Apple’s CoreCrypto for the iOS part of your Kotlin app, 35 | `iosMain` would be the right folder for such calls. 36 | 37 | * `/iosApp` contains iOS applications. Even if you’re sharing your UI with Compose Multiplatform, 38 | you need this entry point for your iOS app. This is also where you should add SwiftUI code for your project. 39 | 40 | * `/cliApp` contains the command-line interface application code. 41 | It uses the shared library to provide 2FA functionality through terminal commands. 42 | The CLI is built using Clikt framework and provides features like: 43 | - Display 2FA codes with auto-refresh 44 | - Add new accounts 45 | - Show platform information 46 | 47 | * `/sharedLib` is a shared library that contains the core 2FA functionality. 48 | It is used by all applications and provides the logic for managing 2FA accounts, 49 | generating codes, and handling encryption. 50 | The library is written in Kotlin and can be used across different platforms. 51 | 52 | ## DEPENDENCY STRUCTURE 53 | 54 | | App | Codebase | Depends on sharedLib variant | 55 | |-------------------|--------------------------------|------------------------------| 56 | | Android | `composeApp/androidMain` | `jvm` | 57 | | iOS (+ Simulator) | `iosApp -> composeApp/iosMain` | `native` (as framework) | 58 | | Desktop | `composeApp/desktopMain` | `jvm` | 59 | | Web | `composeApp/wasmJsMain` | `wasmJs` | 60 | | CLI | `cliApp` | `native` (as static lib) | 61 | 62 | 63 | 64 | -------------------------------------------------------------------------------- /gradlew.bat: -------------------------------------------------------------------------------- 1 | @rem 2 | @rem Copyright 2015 the original author or authors. 3 | @rem 4 | @rem Licensed under the Apache License, Version 2.0 (the "License"); 5 | @rem you may not use this file except in compliance with the License. 6 | @rem You may obtain a copy of the License at 7 | @rem 8 | @rem https://www.apache.org/licenses/LICENSE-2.0 9 | @rem 10 | @rem Unless required by applicable law or agreed to in writing, software 11 | @rem distributed under the License is distributed on an "AS IS" BASIS, 12 | @rem WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 13 | @rem See the License for the specific language governing permissions and 14 | @rem limitations under the License. 15 | @rem 16 | @rem SPDX-License-Identifier: Apache-2.0 17 | @rem 18 | 19 | @if "%DEBUG%"=="" @echo off 20 | @rem ########################################################################## 21 | @rem 22 | @rem Gradle startup script for Windows 23 | @rem 24 | @rem ########################################################################## 25 | 26 | @rem Set local scope for the variables with windows NT shell 27 | if "%OS%"=="Windows_NT" setlocal 28 | 29 | set DIRNAME=%~dp0 30 | if "%DIRNAME%"=="" set DIRNAME=. 31 | @rem This is normally unused 32 | set APP_BASE_NAME=%~n0 33 | set APP_HOME=%DIRNAME% 34 | 35 | @rem Resolve any "." and ".." in APP_HOME to make it shorter. 36 | for %%i in ("%APP_HOME%") do set APP_HOME=%%~fi 37 | 38 | @rem Add default JVM options here.
