Docs / Security Architecture

One secure core on every platform.

9Core owns vault storage, encryption orchestration, key lifecycle, history, and deterministic synchronization behind every native app.

Offline-first vaults

Your vaults remain usable without an account, subscription, or permanent connection.

Keys and locking

Lock 9Secure whenever you are finished and protect access to every device that can unlock your vaults.

Recovery and backups

Keep current backups and recovery material somewhere separate from the devices that hold your working vaults.

History and recovery

The encrypted operation log retains changes for password history, undo, and restore without becoming the source of truth for sync.
