Custom link name

Must be 8–10 lowercase letters or numbers. A short, guessable name is easier for others to find — leave this off unless you need it.

Duress password (optional)

Set a second password and a decoy note. If someone forces the recipient to open this note, they can hand over the duress password instead — it shows the decoy, never the real note, and the real note is destroyed. Tell the recipient both passwords out of band.
