Russell russell@uid.ovh Your passwords, encrypted and synced. No account needed.
Submarine keeps your passwords, cards and notes safe and in sync across your devices, with no account to create. Everything is encrypted before it is synced, so nobody but you can read it, not even us. Your vaults live on Nostr relays: open servers that anyone can run, and that only see encrypted data. When you create a vault, Submarine gives you its key. That key opens your vault on your other devices, so keep it somewhere safe: if you lose it, nobody can recover your vault. - Logins, cards and secure notes, with your own custom fields. - Two-factor authentication codes next to your logins. - A generator of strong passwords, passphrases and usernames. - Import your passwords from Bitwarden, and export them at any time. - A lock password, with your fingerprint, face or screen lock as a shortcut. - Copied passwords cleared from the clipboard after a delay. - Screenshots blocked unless you allow them, and the app hidden in recent apps. - The same vaults on your computer and on the web. Free and open source. No ads, no tracking. Already using Nostr? A signer app such as Amber can hold your vault keys. Submarine is still young. For your most important passwords, we still recommend a proven password manager.
