A passphrase is an advanced setup option, so the first question is not whether it sounds useful. The first question is whether the reader can keep recovery phrase backup, PIN handling, and passphrase memory in separate records. If that separation is not clear, stay with the standard initialization flow until the basic record is stable.

Confirm the basic setup first
Do not review the passphrase option before the basic initialization record is clear. The setup baseline should include app entry, device screen state, PIN boundary, recovery phrase backup, and completion note. For that baseline, use What Is Ledger Initialization.
Separate passphrase from the recovery phrase
The recovery phrase and passphrase are not the same record. The recovery phrase is recorded offline during setup. The passphrase requires a separate memory and handling plan. Review What Is a Recovery Phrase before deciding whether this advanced option is suitable.
Check whether the record habit is ready
A reader considering passphrase should be comfortable maintaining a non-private completion note without writing private values into it. If the PIN boundary is still unclear, compare with How to Choose a Ledger PIN During Initialization.
Decide by maintenance ability
The practical decision is about future maintenance: can you remember the passphrase handling plan, keep it separate from the recovery phrase, and avoid mixing it into ordinary notes? If not, the standard setup path is easier to review.
If the option is enabled later, the local note should record only that an advanced option was reviewed or configured, not the passphrase itself. Keep the note short: date, device state, app entry, and next review item.
This article does not recommend the option for every reader. It gives the boundary for deciding whether the reader’s setup habits are ready for it.
