Profile
The profile page holds your username, full name, date of birth, gender, phone and country code. To change your photo, click the current one.
The email address cannot be changed here — the account belongs to the central sign-in service. If the address has to change, ask an administrator.
Language
The interface language is chosen here. The choice is stored on the account, so signing in from another computer gives you the same language.
Timezone
All dates and times are shown in your timezone. If you work from another city, setting this correctly matters — otherwise due dates appear shifted by a few hours.
Password
A separate section changes the password: current password, new password and a confirmation. The new password must be at least 6 characters.
