ViCare - re-enter login credentials?

Dear all,

I had to change my password for my Viessmann App ViCare. Ever since my login of the corresponding of the integration does not work any longer. However, I am not sure how to change the login credentials of the integration - there is nothing in the secrets.yaml or configuration.yaml. I wanted to avoid removing and reinstalling the integration to not loose the history of the entities.

Thank you for your help!

Below the detailed log in case this is helpful:
