If you have multiple user accounts on your operating system, each user will need to log in separately to Cradle Hub to activate their products. Each activation will contribute to the 3 machine activations, as per each Cradle product license.
If you wish to change the account that is currently signed in to Cradle Hub, head to the
settings menu in the top-right corner of Cradle Hub, click the
sign out button, and confirm the sign-out in the corresponding browser window. A new Cradle user can then sign in to Cradle Hub.
