Features

Everything you need.
Nothing you don't.

Keya Authenticator generates TOTP and HOTP codes for any service that supports standard two-factor authentication.

🔑

Keychain Security

All secrets are stored in the iOS Keychain with the strongest protection class — locked to your device and unavailable when the screen is locked.

🫣

Face ID & Touch ID

Unlock your tokens instantly with biometrics. A 6-digit PIN fallback is always available, with automatic lockout after repeated wrong attempts.

📷

QR Code Scanning

Add any account in seconds by scanning a standard otpauth:// QR code. Works with Google, GitHub, Dropbox, Amazon, Microsoft, and hundreds more.

📦

Import & Export

Import from Google Authenticator, Aegis, 2FAS, and Raivo. Export as QR codes, plaintext, or AES-256-GCM encrypted backup files.

⭐️

Favorites & Reorder

Star your most-used accounts so they float to the top. Drag to rearrange the rest — your order is remembered across launches.

⏱️

Next-Code Preview

Before the current code expires, the next one appears early — so you never have to race the countdown timer.
