So I’m sure once you start accumulating your precious coins you’re going to want to keep them safe & secure.
In this tutorial, I will show you how to create a super- secure and easily memorable passphrase of between 10 – 20 random words. Let’s get started:
- Get 5 dice (standard six-sided)
- Take the 5 dice, put them in a shoe box or cup, shake them up and let them drop on a table.
- Record the 5 numbers from left to right. Example: 25361
- Repeat steps 2 thru 3 for a minimum of 10 times and write them down in a column.
- Open this dictionary list of 7,774 words and find the corresponding words then write them in a second column next to the numbers.
- Discard the numbers, connect the words and create your passphrase. I like to use all upper case letters with no spaces in between. You can choose your own formula.
The rolls of the dice are what generate randomness and the word list gives you a large enough data set to pull from. Using this method a 20-word passphrase has256 bits of entropy but a 10-word passphrase at 128 bits is more than enough.
How to memorize your passphrase:
A really simple method is the Link Method of memorization. It was popularized by the memory expert Harry Lorrayne. The link method involves creating an outrageous visual image for each word and then linking them in a chronological story.
Create your images and story; study them for about 10 minutes and you are done! All you have to do at this point is remember the first word, visualize the story, and the others will follow. Practice it several times a day for several days and you will have it down. Thereafter, recite it once a week to keep it fresh. Incidentally, these work great for creating brain wallets.
If you want to keep a backup of your passphrase split it up into two or more pieces and then store them separately in multiple different locations (ie., one with a friend and one with a relative).
Now you have a super-strong passphrase! Now keystroke loggers are another story…
