Dad: Son, what is a passphrase?
Son: Hi Dad,
The BIP39 standard supports an optional 25th word, a so-called passphrase. The passphrase encrypts the seed and creates a new wallet.
Dad: Son, do I have limitations? Size, or something?
Son: On the Coldcard hardware wallet for example, passphrases are limited to 100 characters in length. The on-screen interface supports ASCII characters only.
Dad: Okay, that is a powerful feature!
Son: So little effort and so much more security.
