R2D2 Secure Authenticator

Secure two-factor authentication with 100% transparent code

Military-grade 2FA security with 100% transparent, auditable code. Tired of authentication apps that are "black boxes"? Welcome to R2D2, the authenticator built for those who don't compromise on security. While other extensions hide their inner workings, R2D2 is built on a radical premise: trust is earned through transparency. UNCOMPROMISED SECURITY R2D2 uses state-of-the-art technology to protect your digital keys: Argon2id Hardening: We use the world’s most robust key derivation algorithm (Argon2id) to protect your Vault against brute-force attacks. AES-256-GCM Encryption: Your accounts are stored locally using authenticated encryption. Your secrets never leave your browser. Critical Isolation: Heavy cryptographic operations run in isolated environments (Offscreen API) to ensure both performance and security. SEAMLESS USER EXPERIENCE Smart Autofill: Automatically detects 2FA input fields and injects codes with a single click. Say goodbye to manual copy-pasting. Time Synchronization: Are your codes being rejected? Sync against Google’s servers to fix clock drift in milliseconds. Secure Cloud Backup: Create end-to-end encrypted backups directly to your own Google Drive. You hold the key; you keep the control. 100% AUDITABLE & OPEN R2D2 has zero external dependencies, zero third-party "black box" libraries, and zero telemetry. Every line of code is visible, documented, and easy to audit.
