Kinko

Personal password vault with on-device encryption, browser extension and mobile app.

Kinko

Overview

Kinko stores logins, passkeys, cards and notes encrypted on the device itself, keeping everything in sync across the main app, the browser extension and the mobile app. Around the vault sit the everyday tools: password generator, vault health diagnostics, item revision history, ephemeral link sharing, emergency kit and backup and restore routines.

Complete ecosystem

Encrypted on the device, yet available everywhere it needs to be: web and desktop app, browser extension for quick autofill and mobile app, plus ephemeral links to share a credential without leaving it exposed.

Why I built it

It came from wanting direct control over my own credentials without relying on third-party commercial vaults, while keeping the convenience of browser autofill and mobile access.

What it does

  • On-device encryption for logins, passkeys, cards and notes
  • Synchronized browser extension and mobile app
  • Vault sharing and secure delivery via ephemeral links
  • Vault health diagnostics, password generator and revision history
  • Emergency kit, import tools and backup with restore
