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.

The Bitcoin journey starts from here, those 24 words. While most people use them, few truly understand them. Taking control of your Bitcoin means generating your own seed securely, without relying on third parties.

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.

Our goal is to generate a large, truly random binary number by rolling the dice.

Writing down a binary private key accurately is difficult for humans, and entering it correctly into a wallet is even harder. A single mistake could lead to losing Bitcoin. While a computer can detect errors using a checksum, handwritten notes cannot.

A private key starts as a binary number. While it can be converted into different formats, at its core, it remains a binary number because that’s what computers understand.
