Creative Cloud and all associated application keep asking to access account.

yes, av = antivirus is the most common culprit but any security app and even space savings apps among others can cause the problem.

I only have windows security, no anti-virus if that is what you mean.

oh, my misread.

something on your computer (typically av) is corrupting your stored adobe sign-in credentials when your shut down or start up your computer.

Hi, thanks for your reply.
I wrote I'll have TO access again.
After a restart, usually on a new day, I have to sign in again to either Cloud or Photoshop.

what do you mean by, "if i shut down the pc, i'll have access again"?

how do you access with your pc shut down?  do you have another device you are using?  do you mean you restart your pc? something else?
