- If you have a cooperation partner / institute at TU Darmstadt, please ask them to create an external “guest TU-ID” for you, which is a prerequisite for a HLR account.
- If not, please send a digitally signed email from your professional mail address to hhlr@hrz.tu-…, in order to get an external (guest) TU-ID assigned by us.

Preliminary by E-Mail


We accept scans of the completed and fully signed forms also by E-Mail for preliminary setup/renewal. However, for legal reasons the paper original is required to be sent nonetheless via office post (address see the “Contact” button right of this text).
To see the expiry date of your own user account, use the command
/shared/bin/account_expire
after logging in.
Apart from that, you will receive an email reminder 4 weeks in advance, and at the exact day of your account's expiration.
Renewal
To renew your HPC user account, use the same form with the same signatures and with the same procedure as described above.
Since your HPC user account is based on your TU-ID, you will retain the same login name (= TU-ID).
Unless you were inactive for more than a year, all data in your home directory will still be there, too.
Please note: the validity term of the HLR user accounts is completely independent of any associated project!
As projects may have several users and any given user might be associated with several projects, there is no easy way of unison. Your user account could thus expire even while you are associated with a project still running.
How to set or change my Lichtenberg password?
Since mid of 2020, your HLR login password is synchronized with your TU-ID password..
New users
For all new users (and users changing their main TU-ID password), the “Lichtenberg” HLR password is in sync with your TU-ID password. You log in to the HLR with the same password you set for your TU-ID.
Existing users
For that to establish for your own TU-ID, please log into the (SSO – Single Sign On), and change your TU-ID password to a new one. A few seconds later, you should be able to current IDM system of the TU Darmstadt with that same password. log in to the HLR
As long as you don't actively change your TU-ID password, your HLR login password remains the old (or last) one you have set yourself on the former “ANDO” portal.
The above holds true also for Guest-TU-IDs.
