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