Researchers who have been approved by HDR UK to login. All users must agree to terms and conditions of use. The first method is via OpenAthens which is a UK-wide identity federation that allows anyone with a recognised institution to login to any service under the federation. They use their institutional account to login and on sign up are required to agree to the HDR UK Gateway T&Cs. The second method is via logins using LinkedIn or Google. These users can request access but this redirects them to a ticketing system which requests extra information about them and an email verification check. This information is then manually verified to confirm they are a bona fide researcher before they are given access. HDR UK plan to review these types of accounts every six months to ensure they still have a valid reason to access the query portal.
