  description

  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.
  
  MULTILINGUAL BY DESIGN Ready for global use with full support for 10 languages, including English, Spanish, German, French, Italian, Portuguese, Chinese, Japanese, Arabic, and Hindi.
  
  
  Why choose R2D2? In an era of security breaches and compromised extensions, the best defense is a tool with nothing to hide.
  
  R2D2: Where trust is transparent code. Install now.
  
  What's New (First Release):
  
  "Initial Release: Full TOTP/HOTP implementation with Argon2id hardening, smart autofill, and secure Google Drive backups. 100% auditable code in 10 languages."

  R2D2 facilitates managing 2FA codes and autofills forms to expedite access. The tool protects credentials locally through advanced encryption.
  
  R2D2 facilitates generating and managing two-factor authentication (2FA) codes. The interface prioritizes usability to expedite account access and keeps data secured on the local device.
  
  USAGE AND INTERACTION
  
  Autofill fields: The extension detects 2FA inputs on webpages. Upon clicking, the system inserts the corresponding codes to streamline login.
  
  Synchronize the clock: R2D2 links its internal clock with Google servers. This process adjusts time drifts and ensures the validity of the generated codes.
  
  Back up data to the cloud: Users save their configurations directly to Google Drive. The system encrypts the information before transmitting it to maintain key control on the client.
  
  SECURITY MECHANISMS
  
  Derive cryptographic keys: The tool employs the Argon2id algorithm to derive keys. This protects the password vault against external access attempts.
  
  Encrypt locally: The system encrypts accounts using the AES-256-GCM standard. Data remains stored exclusively within the browser.
  
  Isolate critical processes: R2D2 executes intensive cryptographic operations in separate environments via the Offscreen API. This separation maintains the performance of the main interface.
  
  TRANSPARENT ARCHITECTURE
  The repository exposes the source code and omits third-party libraries or telemetry systems. Users can review the lines of code directly in their browser or the public repository to audit processes independently.
  
  MULTILINGUAL SUPPORT
  
  Operate in 60 languages: The interface includes translations for sixty languages. This ranges from English, Spanish, French, and German, to Hindi, Arabic, Japanese, and multiple regional variants, to facilitate global use.
  
  What's New (First Release):
  Implements TOTP/HOTP protocols. Detects and autofills fields on webpages. Protects keys with Argon2id. Enables encrypted backups to Google Drive. Supports 60 languages.
