How to create an user in azure portal with read only access to all resources in all subscription?

Question

I want to create an user in azure portal with read only access to all resources in all of my subscription. This user should not be able to modify any thing in any of my available subscriptions.

Answer 1

Seems You are trying to add a user who should have read only access to all resources in all of your subscription beside This user should not be able to modify anything on the tenant.

So the best way is to add that user as Global Reader(Can read everything that a global administrator can, but not update anything.) Role Which provides authority to access all resources in all of your subscription but cannot modify anything among the available subscriptions.

Hope this would help you.
