I must login to Support Community every time

I have/use one account for these forums and my Adobe account at https://account.adobe.com/products

Another question: Is it the same login for Adobe Support Community and the "general" Adobe Creative Cloud login? A new account for me started to be registred in Adobe Support Community without my intention, but I have interrupted that until I know...

On this new forum, you should use a good browser like Chrome or Firefox that accepts cookies and does not have script blockers. 

akmu, Hello.

As John T Smith says, every time you open a forum, you will be automatically logged in with your AdobeID, regardless of your login preferences.
Because you are logging in again, you may be asked to enter a 6-digit number if you have enabled 2-step verification for AdobeID. How about disabling 2-step verification with reference to the following document?
(Disabling 2-step verification increases security risks)

I haven't set up 2-step verification, but I have never been asked to enter a 6-digit number when logging into the forum.

This is new forum software, and now everyone must log in each time they come to the forum after being away
