About this app

Zelen Auth Code is a modern, privacy-focused two-factor authentication app that generates secure time-based one-time passwords (TOTP) for your online accounts.

Designed for simplicity and control, it works with any service that supports standard 2FA — without locking you into a specific platform.

🔐 HOW IT WORKS
Add accounts by scanning a QR code or entering a secret key manually.
Zelen Auth Code generates secure 6-digit codes that refresh every 30 seconds using the industry-standard TOTP (RFC 6238) algorithm.

⏱ REAL-TIME COUNTDOWN
Each account includes a live countdown timer showing when the current code will expire. A visual indicator helps you quickly see when a new code is about to be generated.

✨ KEY FEATURES
• Quick copy — tap a code to copy instantly
• QR code scanning for easy setup
• Manual key entry (Base32 support)
• Support for multiple accounts
• Works offline after initial setup
• Clean and simple interface with no unnecessary distractions

🛡 SECURITY & DATA
Account data is securely stored and associated with your account for backup and recovery purposes.
Zelen Auth Code is designed to minimize data collection and only uses essential services required for authentication and app functionality.

📱 MODERN DESIGN
Built with a clean dark interface and intuitive layout for comfortable, everyday use.

⚠ IMPORTANT
Always keep backup codes provided by each service. Losing access to your authenticator without backups may prevent you from signing in to your accounts.

Compatible with most services that support TOTP-based two-factor authentication.
