Dai Vernon Password Manager – Zero-persistence cryptography for on-demand password access

Summary: Dai Vernon uses zero-persistence cryptography to generate master passwords and vault keys on-demand without storing them. It eliminates the traditional encrypted vault, enhancing security by destroying keys after use. It supports importing from KeePass/CSV and multi-user cryptographic isolation.

What it does

Dai Vernon generates master passwords and vault keys only when needed, then removes them from memory, removing the need for an encrypted vault. It allows importing data from KeePass and CSV files and supports multiple users with cryptographic isolation.

Who it's for

Users seeking a password manager without stored vaults, including those needing multi-user support and secure import options.

Why it matters

It prevents vault theft by never storing passwords or keys, reducing attack surfaces common in traditional password managers.
