If you get a message that the keyword doesn’t work, it is because it has been used before or you typed it incorrectly. Double check that you typed it right. A keyword can only be used one time. This is to make sure that only one device is connected to AV1, and that the correct user gets access.
Are you a school or an organisation with several AV1s? Contact our customer support team to get access to our administration tool where you can generate new keywords.
