The level of sensitivity of your data will determine who can access it. Some data might only be accessible to a small number of individuals, and other data might be accessible by the entire project group.
Even for working data, consider strategies to minimise restrictions on sharing. These may include anonymising or aggregating data, gaining participant consent for data sharing, gaining copyright permissions, and agreeing to a limited embargo period. It might not be necessary to collect sensitive data for your research which then reduces the classification level and who can access the data.
