I made a thing! It pretty much works as envisioned. =D

SeedPass is a secure password generator and manager built on Bitcoin's BIP-85 standard using Python. It uses deterministic key derivation to generate passwords that are never stored, but can be easily regenerated when needed via an index. By integrating with the Nostr network to store the index, SeedPass ensures that your passwords are safe and accessible across devices. The index for retrieving each password is securely stored on Nostr relays, allowing seamless password recovery on multiple devices without compromising security.

SeedPass needs a ton of features and a decent desktop or mobile UI, or maybe even a browser extension or something, but the terminal app works pretty well.

You only need a 12 word seed and your app password to back up and retrieve (theoretically) unlimited number of passwords.

Needs more testing and security evaluation before anyone should use for serious password storage. =)

I had a ton of fun making it! Check it out at:
