Explanation
It is possible to control the hours of the day during which a user may log into the vault by using the Time Restrictions feature. This feature allows administrators to define the days and times that users can access the vault. Users who try to log in outside the permitted hours will be denied access and receive a message informing them of the restriction. Time restrictions can be applied to individual users or groups of users.

Explanation
When using PVWA bulk-upload to add multiple accounts from a file, the minimum permissions required are to add accounts, update account content, and update account properties. These permissions ensure that the user has the ability to create new accounts in the Vault, modify the content of the accounts, and change their properties as necessary during the bulk-upload process1.
