"ATTENTION: New HP sign-In experience
HP Passport has been replaced with a new HP Sign-In experience. There is no need to create a new account, as your HP Passport email and password were automatically migrated and will continue to work in the new experience. Note, you may not be able to use your custom HP Passport username, since HP Sign-in only uses email. For more information about registering, resetting passwords, etc., refer to the MyHPSupport Help page, FAQ page, or User’s Guides".

Register for a MyHPSupport account. An HP Sign-In registration is separate and ultimately needed for sign-in.
