Description
Authly – Offline Authenticator
Authly is a fast, minimalist two-factor authentication (2FA) app that keeps your one-time passwords secure — even without an internet connection. Built for speed and privacy, Authly generates standard 6-digit TOTP codes that refresh every 30 seconds, compatible with Google, GitHub, Twitter, Dropbox, and thousands of other services.
๐ Privacy First — No Account Required Use Authly completely anonymously. Your 2FA secrets are encrypted and stored locally in your device's secure storage — never in plain text, never exposed. No sign-up needed to get started.
โ๏ธ Optional Cloud Backup Want to back up your tokens? Sign in with your email to enable encrypted cloud sync via Firebase. Your secrets are encrypted on your device before they ever reach the cloud — we never see your raw keys.
โก Key Features
Generate TOTP codes compatible with any authenticator-supporting service
Add tokens by scanning a QR code or entering a secret key manually
Biometric app lock — protect access with fingerprint or Face ID
Encrypted local storage using your device's secure enclave
Optional end-to-end encrypted cloud backup and restore
Dark mode (true pitch black) and clean white light mode
Smooth liquid glass UI with animated 30-second countdown timers
Works fully offline — no internet required for code generation
๐จ Beautiful by Design Authly features a distinctive "liquid glass" interface — frosted glass cards, subtle animated gradients, and fluid transitions that make managing your 2FA tokens a pleasure, not a chore.
๐ก๏ธ Security Architecture
TOTP secrets are stored using flutter_secure_storage (device keychain/keystore)
Cloud sync uses AES-GCM client-side encryption — secrets are encrypted before upload
Firestore never holds plain-text 2FA secrets
Biometric unlock via device-native authentication
๐ Compatibility Works with any service that supports the standard TOTP/HOTP protocol, including but not limited to: Google, GitHub, Microsoft, Dropbox, Amazon, Coinbase, Discord, and more.
Authly does not collect any personal data in local-only mode. Cloud sync requires an email address solely for account management. See our privacy policy for full details.
