Why passw0rd?
Built from the ground up with security, privacy, and simplicity in mind.
Zero-Knowledge
Your master password never leaves your device. We can't decrypt your data — even if we wanted to.
Lightning Fast
Local-first vault access that loads instantly everywhere, so your passwords are ready the moment you need them.
Open & Transparent
Fully open source. Audit our code, verify our claims. Your security shouldn't require blind trust.
Military-Grade Encryption
Every password is encrypted with AES-256-GCM using a key derived from your master password through PBKDF2 with 600,000 iterations.
Authenticated encryption ensuring both confidentiality and integrity of your data.
600,000 iterations of key stretching make brute-force attacks computationally infeasible.
Encryption and decryption happen entirely in your browser. Keys never touch our servers.
Uses browser-native cryptographic primitives. No third-party crypto libraries needed.
Clear Setup Flow
- Install the browser extension first (main product experience).
- Open the extension popup and choose Google, GitHub, Passkey, or Local mode.
- Create your master password to encrypt/decrypt vault data locally on your device.
- For cloud accounts, visiting usepassw0rd.com after web login lets the extension sync your auth token, but your vault still requires the master password.
If an attacker gets your Google/GitHub account, they still need your master password to decrypt vault data. Use passkeys + MFA on your identity provider for stronger account security.
