Your name — shown in the staff directory and on every record you touch. Change it and
save; history keeps working either way.
Email — read-only. Your email is your sign-in identity and there is no change-email
flow; the field says so: "Email (read-only)".
Password — needs your current password, and the new one must meet the
password rules.
Language — the language the app is shown in, offered when your business's country has
more than one: "Applies straight away, on this device." No save button — it just
switches.
