How is a KTH Account created?

A KTH Account is created and generated in the central user database, mainly based on two sources of information: study documentation about students (Ladok) and staff registration (HR+).
Creating accounts manually is only performed as an exception, for people with KTH connection that need the resource without existing as a student in Ladok or employed by KTH in HR+. A responsible person at a school, department or equal need to order the account before it is created.

Why did I get this username?

Usernames are automatically chosen by the system when imported from the source systems. The system then create a non-existing username between 2 and 8 characters in length based on the user's first- and/or family name. If no such combination is available, digits might be included in the username.

Can I change my KTH username?

Changing username is only permitted by exeption. Other systems using the content of the users database are no updated atomatically hence the user might end up with undesired problems.
Exceptions taken into account:

  • if the username is offensive (for instance if it resembles a curse in some language and such)
  • if the name the username was based on changes
  • if the username was based on a misspelled name

A user can not change their username by themselves and need to contact the local IT-support for assistance.

What information about me is stored in the user database ?

Personal information in the user database are mainly your full name and social security number. Social security number is for restricted use, for instance to identification when retrieving a new KTH password. Most of the systems use the individual, unique KTH-ID to identify the user.
In the user database there is also information about group affiliations, mainly according to Ladok (courses and study program) and staff registry database (institutions and units), manually administered groups do exist too.

What is a KTH-ID?

Your KTH-ID is a unique identifier in the central user database, KTH-ID are implemented for fewer implementations depending on social security numbers. Social security numbers are unsuitable to use due to restrictions, they can be changed, and some people also lack social security number (for instance foreign guests).
A user do not have to memorize the KTH-ID, username and password works out just fine.
