I am so fed up with hardware wallets at the moment, that I'm pretty much exclusively using airgapped encrypted devices and paper wallets for my non-hot wallets.
I am not going to recommend anyone to use paper wallets that can create much bigger problems for general population than hardware wallets ever would.
But I agree with you that hardware wallets are a mess now and most of them are living in their closed ecosystem just trying to make some profit from this devices.
DIY might be the best option that is flexible and you will be able to adjust accordingly if something changes in future.
Whatever you choose, best thing is to keep everything simple and don't complicate to much.
You were probably referring to the PIN code, not a password. The guy in the video forgot his PIN. More precisely, his friend, the professional poker player who has a photographic memory, forgot a 5-digit PIN code
Pin code is the password in this case that only contain numbers, and it's tied to specific device.
I was not talking about passphrase that is something totally different from password or pin.
