We generate pairs of unscrambled seed phrases. We keep one, the customer keeps the other. ($)
We generate scrambled seed phrases scrambled with random passwords. We keep one scrambled seed phrase, and the customer can choose to give a copy of the password (and presumably keep them in separate locations). Thus, the only person with both the scrambled seed phrase and the password to unscramble it is the customer. ($$)
We offer to generate pairs of scrambled seed phrases with their passwords. The customer provides us with a password. We then produce the copies of both and provide them to the customer. ($$$)
The customer generates a scrambled seed phrase, and we engrave them for him or her.
