Thus if you want to be able to select an Enum value, the sign-in page should have a dataview, connected to an entity, which contains an attribute of type enumaration.
BUT; why do you need it? After login a new session starts, which doesn’t have access to the object displayed in the dataview with the anonymous session. So first define the usecase and tackle this before creating a page, with dataview etc.

Enumeration as in Specific log in users?
you can try creating a new Entity and generalise it with existing account entity and update the field with the enumeration cakye
