Function Pwd(ByVal strTemp As String) As String

Dim i As Integer, iTemp As Integer, bOK As Boolean, iLength As Integer

'48-57 = 0 To 9, 65-90 = A To Z, 97-122 = a To z
'amend For other characters If required
For i = 1 To 8
    Do
        iTemp = Int((122 - 48 + 1) * Rnd + 48)
        Select Case iTemp
        Case 48 To 57, 65 To 90, 97 To 122: bOK = True
        Case Else: bOK = False
        End Select
    Loop Until bOK = True
    bOK = False
    strTemp = strTemp & Chr(iTemp)

' Initialize the seed using Timer.
Randomize (Timer)

Next i
Pwd = strTemp
End Function

    LastRow = .range("E" & .Rows.Count).End(xlUp).Row
End With

For Each rng In Sheets("Sheet1").range("B2:B" & LastRow)

您没有播种随机数生成器。它必须在每次新运行时播种，以产生随机结果。它默认为某个数字，并且该数字会生成相同系列的密码。您必须通过调用该Randomize函数来播种它。Randomize接受一个论点，即种子。一个好的但不安全的种子是系统时间。
