Can we use ServiceNow as the Identity provider for other portals

[Akash_Yadav]

One of our clients has other home-grown customer facing portals that they are using.
They are implementing ServiceNow CSM with the CSP portal, and would like to use the CSP as the unified landing page for all their customers. So they would like to use ServiceNow as the Identity provider for other portals - i.e. once the customer logs into the CSP, when they go to other home-grown portals, they can be automatically authenticated and logged in.
Do we have any preferred approach ServiceNow suggests to achieve the requirement?

TIA

Hi @Akash_Yadav 

I believe their customers will be from different different organizations. If this is the case, configuring multiple external SSO identity providers and mapping SSO source to every users  will become a very difficult exercise and this solution will not be scalable. Hence,  I recommend you to think of solutions/workaround outside of ServiceNow. 

If you could elaborate your requirement in details, I may try suggesting you an approach but as far as the basic understanding is concerned, I won't recommend you this exercise.

Please mark my answer helpful and correct.

Amit
