## Mnemonic Phrase Encryption

Mnemonic phrase encryption adds a layer of security to the standard seed phrase by requiring a user-defined passphrase or secondary authentication factor to access the underlying keys. Even if an attacker gains physical access to the written seed phrase, they cannot derive the private keys without the additional passphrase, effectively providing a form of two-factor authentication for the wallet.

This is particularly useful for protecting against physical theft or unauthorized access to the backup location. However, this also introduces a risk: if the user forgets the passphrase, the assets are permanently lost, as the passphrase cannot be recovered through the standard seed recovery process.

Therefore, this method requires a disciplined approach to both seed and passphrase management, often utilizing secure password managers or secondary physical backups.
