How do I keep my private key/mnemonic board?

In the world of digital currency, the importance of private keys/mnemonics is unquestionable, but many people still don't know how to keep private keys/mnemonics scientifically and safely. How do individual users protect large amounts of digital currency assets? Please note:
01. HD wallets can generate countless private keys that support multiple chains and multiple addresses through 12/18/24 mnemonics. This is the standard protocol supported by most wallets.
02. Conventional mnemonics storage methods are nothing more than the following two methods:
a. Copy on paper (not fireproof or moistureproof, pets and children may cause devastating blows); b. Save in USB flash drives (key password/fingerprint recognition/waterproof), various hardware wallets, mobile phones and other hardware (the problem is that general storage media have a theoretical lifespan, Pin codes are easy to forget, batteries are damaged and leaking, and strong electromagnetic fires are also difficult to preserve for a long time)
03. Mnemonics can be directly engraved on stones or high-melting-point and non-corrosive metal plates for long-term preservation (refer to various ancient human caves), and stones and metal plates are stored in safes. If someone gets the metal plate physically, they can transfer the coins, which is not safe either. Therefore, you can use a metal mnemonic board + custom password to generate a hidden HD wallet. Only those who have both the mnemonic and the custom password can gain control of the hidden HD wallet.
At present, some wallets support this method, such as the first military-grade hardware wallet "Cobo Vault" launched by Cobo in October last year. The wallet generated only with the mnemonic is used as a sentinel wallet, which only stores a small amount of assets. Once the assets in the sentinel wallet are stolen, it means that the mnemonic has been leaked. At this time, it is necessary to transfer the assets in the hidden HD wallet as soon as possible.
04. The last question: How to save the custom password safely for a long time?
Custom passwords are generally very complex and easy to forget for a long time. They can generally be stored in online password management software such as 1password. After all, if only the custom password is leaked without the mnemonic, the digital assets will not be stolen, and the reliability of these security companies' cloud services is far greater than personal storage conditions.
To summarize:
You can use 12/24 mnemonics + custom passwords to generate a hidden vault. The mnemonics are stored on a metal plate, which is locked in a safe. It is best to memorize it yourself; the custom password is stored in 1password. Even if 1password is leaked, the coins will not be lost without the mnemonics. The advantage is that the coins will not be lost even if the metal mnemonic board is physically leaked. Storing it in 1password prevents long-term forgetting of passwords. Set up a sentinel wallet. Once a mnemonic leak or online password management software accident occurs, transfer assets immediately and generate a new set.
In order to meet the needs of future local tyrants to keep digital assets, in addition to the Cobo vault, we have also made a metal mnemonic board - the Cobo mnemonic board is made of aviation aluminum, which achieves a perfect balance in metal strength, weight and corrosion resistance. At the same time, it can be easily disassembled and assembled, so that everyone can quickly place character blocks. Currently, the Cobo mnemonic board supports recording 12, 18 or 24 mnemonics.
