Hi @Satish Kakad · Thank you for reaching out.
There is no concept of trust between two Azure AD tenants like what we have on-premises AD. I am not sure about your exact requirements here due to which you are considering to create trust. However, the most common case where customers look for trust is, when they want to share the application/applications registered in their tenant with the users of other tenants. If that is what you are looking for, you should consider using multi-tenant application.
