You mean like a 25th word? I have a friend who needs to do that.

Do consider that it will be a single point of failure. The passphrase will not be in de bip39 directory. So one character or capital letter misplaced or forgotten is all of nothing.

This isn’t really new news. This has been a known vulnerability for several years now, and you still need physical access to the device.

Yes. In fact, use a few. Be creative and distribute your stashes. All these years of decentralization and we go back to single points of bitcoiner failure. Sigh. nostr:nevent1qqst2gztprhqqe2ymq48wlunsfa7jqwvyesf9w25padn75kqtfa3hgsprdmhxue69uhhyetvv9ujumn0wd68y6trdpjhxtn0wfnj7q3q8ams6ewn5aj2n3wt2qaw...

Getting the seed is useless unless he gets your passphrase too

Use multisig
