About Fenko Vault | Passkey and MFA Manager

Fenko Vault keeps your passkeys and two-factor codes in one place, on your device, and syncs them across your computers with no cloud account. Sign in without passwords, get your 2FA codes right where your passkeys already live, and stay in control of every credential. Sync is end-to-end encrypted, so your keys move between your devices without anyone else seeing them, not even us. Nothing leaves your device unless you choose to back it up or sync it. Highlights: - One vault for both passkeys and 2FA codes, with filters to show just what you need - A built-in authenticator: time-based 2FA codes with a live countdown and one-tap copy - Add a code by pasting its link, a QR screenshot, or a QR image; it is read on your device, with no camera needed - End-to-end encrypted sync across your devices, with no account to create - An optional PIN that locks the vault and encrypts it on disk - Encrypted backups you export and restore yourself - Works alongside your browser: sites you have not saved still get the normal passkey prompt When a site offers a passkey, Passkey Vault can create it, store it, and sign you back in later, all on your device. Fenko Vault is built for people who want their passkeys and 2FA codes to stay private and portable. Because everything lives on your device, keep an offline backup: there is no recovery if you lose every device and every backup.
