My master password is physically present as a mnemonic device, but not available digitally. Anywhere.

Beyond that I really cannot recommend this book: You need to be able & willing to type your passwords out, which means simpler and shorter passwords. I use 99 character complete random ASCII-strings by default. Try typing that in even once.

But there’s a different, unspoken criticism here: don’t store your database on a 3rd party server, a.k.a. “The Cloud”. I use KeepassXC btw. - and my very own “cloud”.
