Keylet is the privacy-first authenticator that fills your 2FA codes right above the keyboard โ€” without opening the app, and without ever showing a code on screen. From the makers of Authenticator+ โ€” and switching is effortless. Import your accounts in seconds, straight from Authenticator+, Google Authenticator, Authy, Microsoft, 1Password and more โ€” 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 โ€ข AutoFill, done right โ€” tap a verification-code field and Keylet offers the right code. It fills it; it never displays it. Nothing to shoulder-surf. โ€ข Import in seconds โ€” from Authenticator+, Google Authenticator, Authy, Microsoft, 1Password, a backup file, or a screenshot. No second device required. โ€ข Multiple vaults โ€” keep work and personal completely separate, each encrypted on its own. โ€ข Encrypted sharing โ€” hand a code to someone you trust over end-to-end encryption, with a self-destructing expiry. โ€ข Backed up, safely โ€” automatic daily encrypted backups on your device, plus password-protected export. No cloud needed. โ€ข Yours to organise โ€” biometric lock per account, categories, recovery keys and home-screen widgets. โ€ข No ads. Ever. Unlimited accounts, free. Keylet keeps your second factor exactly where it belongs: in your hands, encrypted, and out of sight.
