Profile
Settings → Account: update name and email, change password (current password required), and verify email. Organization owners and admins can enable two-factor authentication (TOTP) for the account.
Language and theme
Interface language is switched from the header locale menu. Light/dark theme is a header toggle stored in the browser, not on the account record.
Current workspace
If you belong to more than one workspace, switch from the workspace menu. There is no extra “create organization” step after you already have one — owners add workspaces from organization settings, within plan limits.
