The Bitcoin Improvement Proposal 39 is an open source industry standard used to generate, backup and recover the private keys of a wallet. A BIP-39 seed phrase (aka. recovery phrase) consists of 12 -24 words that are used to rederive all the corresponding private keys in that wallet.

Yes, you can technically use any BIP-39 seed phrase, however, it is highly advised to use a seed phrase generated on a secure device, such as a hardware wallet.

No, a lock is not included. It is up to you what kind of lock to use. The locking hole can accept a 6mm (0.24in) diameter bolt/lock.

Included with each CryoSeed – Genesis is an ‘automatic punch’. This punch tool has a spring loaded handle, which, when pressed firmly will make a permanent mark on the surface of the metal.

Seed numbers are easier and more compact to encode and engrave onto metal. The BIP-39 standard has assigned each possible seed word to exactly one number between 1-2048. Our handbook will show you exactly how to transcribe a seed phrase into CryoSeed – Genesis.

Without encoding, a seed phrase is easier/quicker to extract, digitize and exploit. Encoding serves as a last layer of defense that may delay an attacker enough for you to move funds to a new and safe wallet.

This is a personal decision that needs to take into account the most relevant risks to your specific situation. Generally, it is good to keep the location a secret between those intended to have access to the funds unlocked by the seed phrase.
