    MS Access 2016 Form Permission

    This has me stumped for the moment. As simple as possible I am trying to password protect a form in my database using the 'username' from windows login.



    Any ideas on how would I go about setting this up? Do I need to create a table for usernames and vba code to the 'On Open' event if so how.

    All responses are greatly appreciated.

    It would I think be difficult and I have to ask why you want to do this anyway.

    If you want to restrict the form to certain individuals then do some/all of the following
    1. Hide the navigation pane so users can only open objects via command buttons on forms - this is a good idea anyway.
    2. Assign your users to different groups and limit the access to certain items by user group. If you want you can still use a password to make it more secure but use the same password for all authorised users
    3. Consider hiding or disabling the buttons to open those forms to no-authorised users
    4. Disable Access options so users can't undo those settings

    Some very basic code for password protecting your form

    Code:
    Private Sub Form_Load()
    Dim PassWord As String
    PassWord = InputBox(“Enter Password”)
    If PassWord = “whatever password you choose here” Then 'open form
      DoCmd.OpenForm “name of the form that you want to password protect”
    ElseMsgBox (“Wrong Password?”)
      DoCmd.Close acForm, Me.Name
    End If
    End Sub
    Note that the above isn't particularly secure not least because the input box entry isn't masked
    I do have code for a masked input box at http://www.mendipdatasystems.co.uk/m...box/4594462216

    There are many other security measures you could add if you want to make your app as secure as possible

    Thank you. I neglected to add I've already hid the navigation pane and I am using the code above to restrict access to a report.

    I would like to create a table using usernames from the windows login giving them access to the form probably based on some kind of group security level.

    I have other forms and buttons that are not restricted I just want this particular form to be restricted to certain users.

    Hope this makes sense.

    Fine so my suggestions were valid. Just forget the idea of matching form passwords to users windows logins.
    In case you are interested see my articles on ways to improve security in Access databases http://www.mendipdatasystems.co.uk/i...ity/4594461803

    Ok, Do you have any experience using the DoCmd.RunCommands below?


    DoCmd.RunCommand acCmdUserAndGroupAccounts to add or delete user accounts.
    DoCmd.RunCommand acCmdUserAndGroupPermissions to edit user permissions.
    DoCmd.RunCommand acCmdUserLevelSecurityWizard to run security wizard.

    These all apply to the old user level security for MDB files which was deprecated in A2007.
    In other words no longer relevant as you have A2007
