Chestword

About

Chestword is a password manager built on one idea: nobody but you can open your vault — not even us. ZERO-KNOWLEDGE, FOR REAL Everything is encrypted on your device with AES-256 before it leaves it. Your master password and your Secret Key never reach our servers, so a copy of our database is useless without them. The complete security design is published on our website, in plain language. WORKS WITH CLAUDE Chestword is the first password manager made for working with an AI assistant. Connect Claude Desktop or Claude Code on your Mac and Claude can look up a login for you — every password needs your Touch ID, nothing goes through a server. Prefer claude.ai? Share one vault with it and keep the rest closed. SHARE WITHOUT TRUSTING THE SERVER Share a vault with family or your team. Each person gets the key encrypted to their own account; compare a short key code to make sure nobody is in the middle. Remove someone and the vault gets a fresh key automatically. EVERYTHING YOU'D EXPECT • Logins with one-time codes (2FA), passwords, secure notes, cards, identities, API credentials and SSH keys. • Passkeys — create and use them from Chestword. • Password AutoFill on iPhone, iPad and Mac, plus a browser extension for Chrome, Edge, Brave and Arc. • Lookout: find weak and reused passwords and logins without two-factor authentication, with an optional anonymous breach check. • A strong password generator and a Recovery Kit with a QR code to sign in on a new device in seconds. • Import from Apple Passwords, Chrome, 1Password or Bitwarden. • Works offline; changes sync when you're back. NO TRACKING No ads, no analytics, no third-party code. Built in the Netherlands by Greenancy.
