To connect Knight Manager with Alexa, you need to first set up the account linking in the Alexa app. Simply open the Knight Manager entry in the Alexa store, tap on "Settings", and select "Account Linking". Then, just log in with your Amazon login credentials.

It's important to start the skill first, as the information is only transferred when the skill is launched. After launching, you should be able to log in to the Knight Manager website. As a bonus, you will automatically receive 10 diamonds every day as a reward for successfully linking your account.
