    SimpleX

    SimpleX

    The first messaging platform operating without user identifiers

    Other apps have user IDs: Signal, Matrix, Session, Briar, Jami, Cwtch, etc. SimpleX does not, not even random numbers. This radically improves your privacy. The video shows how you connect to your friend via their 1-time QR-code, in person or via a video link. You can also connect by sharing an invitation link. Temporary anonymous pairwise identifiers SimpleX uses temporary anonymous pairwise addresses and credentials for each user contact or group member. It allows to deliver messages without user profile identifiers, providing better meta-data privacy than alternatives. Many communication platforms are vulnerable to MITM attacks by servers or network providers. To prevent it SimpleX apps pass one-time keys out-of-band when you share an address as a link or a QR code. Double-ratchet protocol. OTR messaging with perfect forward secrecy and break-in recovery. NaCL cryptobox in each queue to prevent traffic correlation between message queues if TLS is compromised.

    2FAS Pass Android

    2FAS Pass Android

    Source code for 2FAS Pass Android app

    2FAS Pass Android is the open-source Android implementation of the 2FAS password-protected authenticator and secure vault project, which blends two-factor authentication (2FA) token generation with a secure vault for managing verification codes and potentially other sensitive credentials. While specific repo details vary by the community project, in the broader 2FAS ecosystem the Android clients are designed to generate TOTP (time-based one-time passwords) and HOTP codes for users’ accounts, helping them meet modern multi-factor authentication needs through a simple, private user interface that works offline and without needing an account. The app supports scanning QR codes to add new authentication tokens, allows local encrypted storage of secrets, and can restore tokens from backups or synced devices. 2FAS focuses on privacy and simplicity—tokens aren’t sent to third parties, metadata isn’t stored externally, and users can secure the app with biometrics or passcodes.
