# Manage data governance and access control
Use *protected aliases* to represent key stages of your model development pipeline. Only *Model Registry Administrators* can add, modify, or remove protected aliases. Model registry admins can define and use protected aliases. W\&B blocks non admin users from adding or removing protected aliases from model versions.
Only Team admins or current registry admins can manage the list of registry admins.
For example, suppose you set `staging` and `production` as protected aliases. Any member of your team can add new model versions. However, only admins can add a `staging` or `production` alias.
