Profile
Your name, job title, avatar, language and time zone. The time zone is what dates in the dashboard and your digests are shown in, so it is worth setting correctly.
Changing your email
A change is confirmed from the new address before it takes effect — otherwise a typo would lock you out of an account with no password to fall back on.
Sessions
Every browser you have signed in from is listed with its device and last use. Sign out of any of them, or all at once if a laptop goes missing. "Stay signed in" chooses between a long-lived session and one that ends when you close the browser.
Several workspaces
One account can belong to several workspaces — an agency running quizzes for clients, for instance. Switch between them from the account menu; leads, quizzes and settings are entirely separate.
