USB Binding

USB Binding#

USB binding adds a second factor by mixing a fingerprint of your drive into the encryption key itself. The fingerprint is combined with your master password before the key is derived, and PBKDF2 work rises from 100,000 to 150,000 iterations.

A bound vault cannot be decrypted without reproducing that fingerprint. The password alone is not enough.

Enable Binding (Recommended)#

Encrypted vaults will not decrypt without the drive fingerprint. Prevents cloud backup compromise and file-only theft. A second factor without extra hardware.

Skip Binding#

Wallet files remain portable across devices. Useful for testing, shared access, or frequent drive replacement. Reduced security.
