Native on every platform.

Every app runs the same Rust-based 9Core engine. Each vault is its own infinite encrypted container and syncs directly from device to device without relying on cloud servers.

Ctrl+; to summon. Ctrl+1–0 to paste.

• Search every unlocked vault by item title, type, field label, or non-secret field value.
• Search never decrypts concealed fields, and field retrieval decrypts only the selected item.
• Open an item or copy its username, password, or another field directly from the result.
• Use the desktop palette from a global shortcut without switching away from your current task.
• Create a Login from the palette or continue into 9Secure for every other item type.

Sync directly between trusted devices.

• Pair devices once and verify the connection with a six-digit security check.
• Manage which vaults sync to each device.
• Sync device to device over any available connection with mutual authentication and end-to-end encryption.
• Merge changes field by field so edits made on different devices converge deterministically.
• Remove a vault from one device without deleting it everywhere, or explicitly delete it across synced devices.

• Identify weak, predictable, reused, old, and compromised passwords.
• Check password strength locally with pattern and entropy analysis.
• Check known breaches by sending only a five-character hash prefix to Have I Been Pwned and matching the results locally.
• Cache audit results inside the encrypted vault index for fast, offline access.

Built for the post-quantum world.

• 9Secure uses the latest NIST-approved post-quantum standards.
• The Rust-based 9Core engine controls every vault operation, from storage and history to synchronization and key lifecycle, and is backed by source-available Quantum Crypto.
• Unlocking decrypts only the searchable index. Every item and attachment remains independently authenticated, secrets decrypt only on demand, and transient values are wiped after use.
• Every sync session uses post-quantum key exchange, mutual device authentication, and end-to-end encrypted state transfer.
• Each vault uses authenticated append-only commits to preserve its last valid state. Independent records isolate damage, and VACUUM rebuilds the canonical vault without modifying it in place.
