Auth Sync

Auth Sync is a simple and secure authenticator app for Two-Factor Authentication (2FA) using TOTP. Generate, manage, and protect your one-time codes offline, with optional end-to-end encrypted cloud sync when you need it.

🔐 Key Features:

• Generate & manage TOTP codes offline – safe, reliable, always available.

• Quick add via QR scan or manual input (6/8 digits, SHA1/256/512, 30s/60s).

• Organized folders and search to find codes faster.

• End-to-end encrypted (E2EE) Cloud Sync across devices – zero knowledge.

• Secure sharing between your own devices only.

• Export/Import encrypted backups for long-term safety.

• Extra tools: Password Generator, Temporary Email, Base64 encode/decode.

• App lock with Face ID / Fingerprint / Passcode.

• Local encrypted backups with Files or Google Drive.

🛡 Privacy First:

• TOTP secrets are always stored encrypted.

• We do not collect or sell your TOTP data.

• Only minimal data (email for login, crash reports) is used for sync and diagnostics.

⚡ How it works:

1. Open the app and add your first account (scan QR or enter secret).

2. Use codes offline instantly.

3. Sign in only when you want to sync across devices.

4. Export or import encrypted backups anytime.

Auth Sync keeps your accounts protected and makes 2FA easier than ever.
