Antwort auf: Kann die Passphrase geändert werden?
I assume that you mean „24-word seed/recovery phrase“ when you mean passphrase.
Yes, they can for example add a BIP39 passphrase (which will generate a new set of accounts), and transfer all their cryptos to those new accounts.

Or they could also reset their ledger and generate a new „24-word seed/recovery phrase“ and transfer all their cryptos to the new accounts, but it will require more work (or spending more gas in multiple transfers via a centralized exchange, compared to using a BIP39 passphrase).
