My adobe account got hacked and hacker changed the email address. What can I do to regain access to my adobe account? I want to the access back to my original gmail. My contributor account is linked with that.

Who had access to your Adobe account log-in information? Did you share it with a “friend,” co-worker or family member?

I ask because sharing credentials is a violation of Adobe’s Legal Terms of Use.

Adobe won’t reactivate a compromised account for security reasons. They’ll permanently terminate it.

You’ll likely have to create a new account under a new ID (email) and password. And this time, protect it with 2-factor authentication.

Good luck.
