Generate a Recovery Phrase With a D8 Die

This method uses an eight-sided die. Each roll supplies three bits, so four rolls create 12 bits and you retain the first 11. Repeat for 12 or 24 words, then follow the final-word procedure.

Roll the die four times for each word and use this conversion table:

Result Bits
1000
2001
3010
4011
5100
6101
7110
8111

Read the accumulated bits from left to right, discard the final bit to leave 11 bits, and use the binary words table to find the BIP-39 word.
