Kryon Authenticator: 2FA

FUSION EDGE LLP

About this app

Kryon Authenticator brings your two-factor authentication (2FA) codes into one place. Generate time-based one-time passwords (TOTP) for your online accounts, with codes available even when you're offline.

Get started without a Kryon account, or sign in to sync across your devices with end-to-end encryption.

Add accounts your way
Scan a 2FA QR code, choose a QR image or enter a setup key manually. Kryon works with websites and apps that support TOTP-based verification.

Keep your codes private
The secrets used to generate your codes are encrypted on your device. When you enable sync, your vault is encrypted before it leaves the device and decrypted on your connected devices. Kryon cannot read its contents.

Use verification codes offline
Generate OTP codes without an internet or cellular connection. Your codes are ready when you're traveling, on a plane or away from a network.

Sync across devices
Use your Kryon account to keep your authentication codes in sync. Join another device using your master password, recovery key or approval from an existing device. Review connected devices and active sessions from the app.

Move from another authenticator
Import codes from Google Authenticator, 2FAS, Aegis and Ente Auth using supported transfer QR codes and backup files. You can also import standard otpauth links.

Keep a backup
Export a password-protected backup file and restore it when needed. Save the recovery key for your synced vault somewhere safe so you have a way back in if you forget your master password.

Find the right code quickly
Search by service or account, tap to copy a verification code and arrange your accounts in the order you prefer. View the current and next code together, with a countdown to the next refresh.

Add protection when you need it
Enable biometric App Lock on supported devices. Choose a light or dark theme and keep multiple accounts organized in one clear view.

A Kryon account and an internet connection are required for synchronization. Adding accounts and generating local TOTP codes work without signing in.
