As you are the main contact you have been set up as an Admin User and can now nominate others from your Business to use your account.
There are 2 types of Users:
Admin User – (like yourself) can make bookings add, remove and manage other users, update company details and / or travel
User - can make bookings, update his or her own personal details and / or travel
Please note: As an Admin User when adding others you will also need to set their passwords and advise them to contact you for their login details.
All can be easily done via the Users tab in your online system.
