can be possible to secure the username and password in server settings that those detials will be hide and can’t be unhide for security purposes of the web server, because if some users knows where to get the username and password the server could be compromise, they can now log in the web server and can modify or delete any of the data in the server could cause trouble with the server administrator…
@shoyhen, maybe could you solve this issue by having 2 different accounts viz. the admin account which should have the admin rights to the survey project, and the enumerators account which could be assigned with data viewing and data submission permissions as outlined in the support articles Managing Permissions and Row-Level Permissions.
The username and the password for the enumerator’s account are different from the username and the password for the admin account. Hence if you provide only the required access to the enumerator’s account, you should have your admin account safe.
