Adobe users need to log in again
Starting on Sunday 12/3, Adobe will be updating its services, which means that as an end user, you will be logged out of all Adobe applications you use, such as Creative Cloud and Acrobat.
When this happens, you will be prompted to sign in again with your AdobeID. All AdobeIDs at KI use the KI e-mail as username, but you, as the user, have set the password yourself.
It might take a few weeks before all users have been prompted to log in.
Password reset
If you don't remember your password, you can reset it by following this guide from Adobe.

Choose Adobe profile
If you are prompted to choose a profile when logging in to your Adobe account, choose the option called "GU- Karolinska Institutet".
If you have logged in to the other profile, you will need to log out and in again, to be sure to reach all Adobe services.
