Your secrets — only yours

PassLocals offers an offline solution for storing passwords, seed phrases, and code words: NFC cards paired with an app. All data is encrypted and stored directly on the cards. The app is used only for reading and writing — no accounts, no servers, no syncing.


NFC cards are contactless cards with a built-in chip (the simplest example is bank cards) that exchange data with your devices. Simply tap a card to your phone to read or update what’s stored on it.

Why This Works
  • No cloud. No servers
    All data is encrypted and stored directly on your NFC card or cards. Nothing is transmitted or stored elsewhere. This removes the risk of data leaks, mass breaches, and reliance on third-party infrastructure.
  • Fully offline. Fully independent
    The system works without an internet connection and does not rely on the continued operation of the developer. Your access remains intact even during outages, restrictions, or service shutdowns.
  • Physical authentication
    Remote access isn’t possible. Your data can only be unlocked when all three key factors are present: a trusted device, one of your NFC cards, and your master phrase.
  • Control your trusted devices
    You define roles, grant or revoke access, and add or remove trusted devices at any time.
Key Features
  • Information stored as encrypted text on NFC cards
    All data — passwords, PIN codes, API keys, access credentials, and secure notes — is stored on one or more NFC cards in encrypted text form.
  • Read and write via the mobile app
    The app is used only as an interface to read from and write to the card — no cloud storage, no accounts.
  • Multiple cards and role support
    Use multiple cards — primary, backup, or service — each with its own access level.
  • Backup recovery via duplicate cards
    Data can be restored using pre-created backup cards, eliminating the need for servers or support involvement.
