Keylet: 2FA Authenticator

Keylet is the privacy-first authenticator that fills your 2FA codes right above the keyboard — without opening the app, and without ever showing a code on screen.

From the makers of Authenticator+ — and switching is effortless. Import your accounts in seconds, straight from Authenticator+, Google Authenticator, Authy, Microsoft, 1Password and more — or even from a single screenshot, with no second device needed.

Your secrets never leave your phone. Everything lives in an encrypted, zero-knowledge vault (AES-256-GCM) that only you can open. No account. No cloud. No tracking. No ads.

WHY KEYLET

• AutoFill, done right — tap a verification-code field and Keylet offers the right code. It fills it; it never displays it. Nothing to shoulder-surf.
• Import in seconds — from Authenticator+, Google Authenticator, Authy, Microsoft, 1Password, a backup file, or a screenshot. No second device required.
• Multiple vaults — keep work and personal completely separate, each encrypted on its own.
• Encrypted sharing — hand a code to someone you trust over end-to-end encryption, with a self-destructing expiry.
• Backed up, safely — automatic daily encrypted backups on your device, plus password-protected export. No cloud needed.
• Yours to organise — biometric lock per account, categories, recovery keys and home-screen widgets.
• No ads. Ever. Unlimited accounts, free.

Keylet keeps your second factor exactly where it belongs: in your hands, encrypted, and out of sight.
