Fenko Passkey Vault

Fenko Passkey Vault keeps your passkeys and two-factor codes in one place, on your device, encrypted. There's no account to create and nothing to sign up for. It works offline.
Passkeys
Sign in to websites and apps with passkeys through Android's built-in autofill. Create new passkeys and use existing ones without a separate password. Your keys are generated and stored locally.
2FA authenticator
Generate time-based and counter-based one-time codes (TOTP and HOTP). Add a code by pasting an otpauth link, scanning a QR image, or pasting a QR screenshot. Codes refresh every second and copy with a tap. Supports SHA-1/256/512, 6 to 8 digits, and custom periods.
One vault
Passkeys and 2FA codes share a single searchable list. Filter by type, expand any entry to see its details, and find what you need fast.
Locked down
Set an optional PIN that encrypts the vault at rest with AES-GCM and gates access behind a lock screen. Lock on demand or let it auto-lock after a timeout, unlocked with your device biometrics.
Sync without trust
Sync your vault across your own devices with end-to-end encryption. There's no account and no central server holding your data. The servers never see your keys or codes — only an encrypted blob passes through. If you lose every device and every backup, no one can recover it, including us. That's the point.
Private by design
Fenko Passkey Vault collects no data, contains no trackers, and asks for no unnecessary permissions. It runs offline. Your secrets stay yours.
