Just like your Bitcoin seed phrase, your passphrase is a critical key to your funds. If you lose it or it gets compromised, your Bitcoin is gone forever. That’s why proper security is essential.

In our basics section, we covered the fundamentals of passphrases. Now, let's dive into how to create a secure and reliable passphrase for your Bitcoin seed.

A passphrase is an additional security layer. Unlike your seed phrase (which consists of predefined words from the BIP39 word list), a passphrase can be any combination of characters.

Now it's time to generate your own passphrase using real dice. As we mentioned in the Seed Phrase Guide, using casino-grade dice ensures the highest level of randomness (entropy). However, if you want to save money, any standard six-sided dice will work just fine. Even if your dice have slight imperfections, rolling multiple dice at a time will still provide sufficient randomness for a secure passphrase.
