Web Security Services (WSS) Partner Portal
As per the WSS General Data Protection Regulation (GDPR) remediation requirements, with the WSS M2.0 portal, Ops and customer support will no longer be permitted to login to the portal as a given tenant until that tenant has granted the permission to do so.
Via the partner portal, a partner can also indicate if the default for the tenant that they create should be to enable or disable the "Allow Support Access" as per the screen shot show below:

3) Click on the switch of option 1 to enable support access to all customer under your partner account.
