Dudou

What is Dudou?

Dudou is a password-less secret manager on a zero-knowledge model. Forget the master password you can lose, reset, or get phished — you write down a single BIP-39 mnemonic phrase once, and it derives your encryption keys locally, so the server never sees them. Unlock on any device with passkeys(fringerprint), store passwords and secret notes end-to-end encrypted, autofill forms in English or Chinese, and sync everywhere. Free to start; PRIME from $1/month.
