Welcome to Vector! No, you don't need to wait for the equipment before you can log in to your new software account. In fact, it is best practice to do so as soon as you have received your registration link via email to prevent it from expiring within 7 days.
You may want to set up your Team and add Athletes or start exploring our onboarding videos whilst you wait for the equipment.
