On our initial release, we use your email domain to validate user credentials.
LINQ Core will be licenses per organisation, not per user, so the email domain is the simplest way to ensure that it is a user within the same organisation who is accessing LINQ.
In a future release, we will be adding to this capability.
For example, we recognise that many organisations have multiple domain names.
We also know that many LINQ users will be working on behalf of another organisation and there is a collaboration requirement.
These additional capabilities will be addressed in time.
