Open Source C# Authentication Software for Mac

Authenticator Pro is a free and open-source two-factor authentication app for Android. It features encrypted backups, icons, categories, a high level of customization, and even a Wear OS app. Unlike some alternative apps, Authenticator Pro gives you control over your data. You can import from other apps and export at any time. Authenticator Pro is a community-backed open-source project which aims to provide privacy and security to users. The source-code is auditable by anyone on GitHub and released under the GPL 3.0 license. The project has no corporate ties or interests but, rather has the purpose of providing a secure and private two-factor authentication solution to the privacy-conscious. Unlike alternative user-hostile applications, Authenticator Pro does not lock-in your data or communicate with distant servers. Everything is safely protected in the app and can be exported at any time.
