7. For the pin you can use letters numbers and special characters; example of pin can be mother's maiden name and your phone number
8. For the bits use 256 for a 24 word passphrase or 128 for a 12 word passphrase; suggest using 256
9. Click the Create button to generate the master passphrase
10. For the site enter the wallet name or website domain where you will use the passphrase; like trustWallet or kraken.com
11. For bits use the same value you used above; do not use a higher value than what you used above

16. Make a few copies of the paper and store them in different place
17. If you want it to be a brain wallet skip writing the reminders on paper; memorize the pin, bits, site and location of the sticks
