I have four licenses from way back, when Malwarebytes sold lifetime licenses, with these licenses having both key & ID. One of the systems was acting up, so I deactivated Malwarebytes, wiped the drive, and reinstalled Windows 10. When I installed Malwarebytes and tried to activate it, I discovered that Malwarebytes no longer accepted key & ID. It demanded that I give it the email address used for the licenses, which I configured years ago. So I tried to login, only to discover that my account was no longer valid. So much for lifetime.
