... I use hardware wallets but they still use a SEED for recovery. A functioning hardware wallet never shows the SEED to any computer.
If the seed is never "shown" to any computer, how do you get the seed in the first place? The hardware wallet has to be connected to the computer... and the seed has to be displayed/output on the computer so you can write it down doesn't it?
At which time, malware that takes stealth screenshots or does desktop video recording could capture your seed right?
