I would like an option for Integrations which allows for updating of credentials. I may be missing something, but the only solution I have ever found is to delete and recreate the integrations with the updated credentials.
With security one of the fundamental backbones of HA, hackers become more proficient, and a new security incident with username/passwords being exposed almost daily this should be a critical addition to HA.
In addition, in most cases HA picks up the new device after deleting the old and recreating the integration, BUT in some cases you have to fix all your automations, scripts, etc. which is almost impossible for large installations.
Shout out to @wkearney99 for this discussion prompting me to submit this request after just dealing with it in the past.
