Features of 2fast – Two Factor Authenticator
- Secure Data Storage: Every piece of data is securely stored within a single encrypted file, utilizing AES encryption with a password-based key generated by PBKDF2. This ensures that your sensitive login information remains private and secure. Users can easily backup and restore their credentials using this single file.
- Local Functionality: 2fast operates locally, eliminating the need for an internet connection or extra accounts for its primary functions. This feature enhances security, as your data is not dependent on external cloud services or online storage. The only exception is for users who opt for the WebDAV feature.
- Cross-Platform Support: Currently available for Windows 10 and under development for Android, iOS, Linux, and macOS, 2fast offers flexibility for users across different operating systems. This ensures that regardless of your device, you can enjoy the advantages of this authenticator. The Uno platform development allows for seamless access across various platforms.
- Open Source Advantage: Being open-source allows for greater transparency and community collaboration. Users can inspect the code, contribute to improvements, and trust that the application is not hiding any unwanted features. This aspect also encourages the development of the app based on community feedback.
- TOTP Algorithm Implementation: Utilizing the widely accepted TOTP algorithm (RFC 6238), 2fast is compatible with various major services, including Google, Microsoft, Facebook, and PayPal. This makes it a versatile option for users looking to secure their online accounts. The familiarity of TOTP ensures a streamlined experience when setting up authenticators across different platforms.
