Access for the Content Management System and PushPad (used for sending notifications) is managed in each respective platform. Provide access to administrators based on the tasks they will need to perform.
Decide what level of access they need according to the above outline, then have an administrator with full administration access create a user account for them.
Offboarding/removing administrators
Deactivate the account of an administrator that should not have admin access any more, rather than deleting them. That will allow edit history to make more sense, because it will still refer to the old account, but they will not be able to continue making changes to the content.
Uncheck the Active check-box and save to de-activate an account
PushPad (sending notifications)
https://pushpad.xyz is a platform used for sending notifications to app users that have subscribed in the app.
Administrators that need to send notifications will need to be added as members of the app project in PushPad.
The PushPad subscription owner account can add members, allowing them to send notifications.
Send the email addresses of each new user, and/or the users to be removed to OpenUp, including a link to this documentation for them to complete the process.
OpenUp will then add/remove the provided accounts to/from the PushPad projects for each of the app environments, as per the needs of each administrator.
