I want is to use client metadata in the hosted login page OR find some way to have that page use the client’s information, not the tenant information. Specifically, I want the client logo to show in that form without hard coding it in.
At this time, to my knowledge, it’s not possible to access client metadata or other client information besides the identifier from within the hosted page in a built-in way. I would suggest posting this suggestion in the ideas space as it’s not the first time I’ve seen it and it will help in collecting the use cases for this particular requirement which is very helpful when analyzing future features. In particular, if you can further detail why you need a client specific hosted login page versus a general one or going with multiple tenants that would be ideal.
