We're running in circles, but since you mentioned it again:
A lot of people now is using MetaMask, they need to save the seed recovery phrase offline, encrypted. They need CryptoPlatz Vault.
They use MetaMask, so they
need to save their seed phrase offline, encrypted? Why do they need that? Someone breaking into their house can also just steal the PC, where the seed is stored, unencrypted, in MetaMask, no?
You mentioned that a text file is not secure. Sure; a virus can access this file. A virus can also access MetaMask's wallet file; right? Where is the benefit of storing an
online seed on an
encrypted offline device?
Again, in my opinion, encrypted, offline backups only make sense if your main wallet is offline, too. But since offline wallets can't usually connect to the cryptoplatz vault, there's no way of transferring the seed except through an online device, which destroys the whole purpose of it all.
You are wrong, Metamask save all the information encrypted on the computer, so if somebody steal the PC, he need to break the encryption.
But if the user leave the seed on a paper or on plate without be encrypted, the thief you have access to the cryptocurrencies.
So if the user use CryptoPlatz Vault, to store the seed, thief will not have access to the seed recovery phrase.
