Your previous login data from Hallesche4u will remain. If you don't have access data yet, you can request them by post.
Alternatively, you have the option of identifying yourself using the eID function of your German identity card. We use the "Nect Ident with eID" service from Nect GmbH for this. Access to Hallesche4u can be activated by briefly comparing ID cards and entering the six-digit PIN. The data is transmitted in encrypted form. The identification process takes about 5 minutes.
