Hi. We all have too many passwords, private keys, adresses, registration informations. I want to askt how you keep them. I dont ask you to explain where you put your ledger wallet

For example, I keep my passwords and private keys on a simple document which I created on my laptop. This means that if I lose my computer or someone stoles it, I may lose too many things. What are your solutions? Is there any safe option? I have to get precautions before it is too late.
Maybe you can transfer your important assets to the same wallet and make sure your device is secure when you get the wallet's private key. You can manually copy the private key and mnemonic. You can try reading N times a day. One day, these ABC... will be recorded in your mind. This is the safest way to store.
