PosterChan Passwords di PosterChan AI

PosterChan Passwords fills your saved logins, generates strong new ones, and shows two-factor codes — for a vault you own.

How it works. Your vault lives as encrypted events on your own Nostr relay. Each entry is sealed with AES-256-GCM under a vault key that never leaves your devices; the relay stores ciphertext it cannot read. You pair this add-on once from the PosterChan app, choosing whether it may only read your vault or also save new logins.

Features
• Autofill on the sites you saved, matched by exact host, registrable domain, or your own per-site rules (starts-with, exact, regular expression, or never)
• Two-factor codes (TOTP), including on the second step of a login, and in forms that split the code across six boxes
• A password generator with adjustable length and character sets, and an honest entropy figure
• Offers to save a new login, or update one you've just changed
• Works offline — your decrypted vault is cached locally
• Reads from every relay you use, so one being down doesn't lock you out
* Browser Bookmark Sync to Nostr

What it does not do. No telemetry, no analytics, no accounts, no third-party servers. It talks only to the relays you paired it with. It never fills a password on a domain you didn't save it for — a lookalike like paypal.com.evil.com matches nothing — and it never hands a password to a page unless you click to fill it.
