Your profile
Your name, a read-only address, why you cannot change your own role, and how to change a password you know.
The account menu in the right of the header carries your name and your role, and inside it Your account, changing your password, and signing out. It is the only place in the application where the address you are signed in with is visible — which is the answer to "which account am I in" on a machine two people share.
Your name
Full name is one field, not two: Runjet never splits it anywhere, so it
does not ask you to split it either. Anyone may correct their own, a viewer
included — your own account is yours whatever your role, and a typo in your own
name is no reason to ask an admin. The change is a user.name row in the
audit log, the same one an admin would have written; the log
already says who was the actor and who the subject.
Your address
Email is read-only, and nobody changes it — not even an admin. It is what you sign in with and what the log recorded you under; a different address is a different account, which can be invited.
Your role
Role is stated with its own sentence (what it means) and is not offered as a choice, not even to an admin: Runjet refuses to change your own role in either direction (why). Another admin can change it.
Your password
Changing your password in the account menu asks for your current password
and a new one; with the wrong current one you get
current password is incorrect. Unlike a
reset by code, this change does not end
your other sessions — you know what you are doing and nothing was taken from
you. A password you do not know is what Forgot your password? on the
sign-in screen is for.
