Don't do that. But you can keep a bip39 high entropy passphrase\password on an online keepass vault.

In fact it's maybe the best way to store your bip39 high entropy passphrase\password. When configured properly.

When I use keepass I also use a key file. The vault online doesn't have the key file. I have the key file. Backed up several ways.

In fact. The vault can use several key files, if I choose to. The key file can also be a text file. Made up of many different things.

Like parts of the Gettysburg address. The solution to a mathematical formula. Or all of these things at the same time.

I can completely destroy the key file. Then easily reconstruct it from memory.

The keepass vault I use. Is hardened and optimized. But even if someone were to get my bip39 high entropy passphrase\password.

They would still need my seed phrase. Which is backed up and Not! stored online. That's just not going to happen lol.

What you people really need to be worried about are those so-called secure elements in many of your Bitcoin hardware wallets.

I consider them just government backdoors. They're closed source, so you don't really know what's in them. Maybe your seed phrase and bio-39 high entropy passphrase.

Kind of silly to trust something like that with money that is based on minimizing trust lol.

Lastly what you do all depends on how much you're trying to secure and the risk you have.

The way I do things for a hot wallet are very different from what I do for a cold storage wallet

Good Luck..🧡😊
