  Hey guys,

  Question for anyone that can help.  My company just put out a new website earlier this week.  Everything is working great, but there are still a few things that need cleaned up. 

  Question is: I'm wanting to create a password generator for those people who have lost/forgotten their password based on their email address and the answer to their secret question.

  Does anyone know how to generate a randomly generated password using SQL?  Or ASP for that matter?

  Any help would be greatly appreciated

  From SQL

  SELECT NEWID()

  You can use RAND() function but I don't like converting the number to varchar so I'd use A globally unique identifier (GUID).

  There are may other ways but this one, I use

  Hi,

  a quick hack is:

  declare @pwd sysname;

  declare @pwd1 sysname;

  select @pwd1=str(rand(datename(ms,getdate()))*1000000000);

  select @pwd=substring(@pwd1,4,len(@pwd1));

  It generates quasi random strings containing 7 numbers.

  Best regards

  here is a function i use on an asp page

  it would be called by using something like this:

  sRegNum = RandomPW(8)

   Function RandomPW(myLength)

    'These constant are the minimum and maximum length for random

    'length passwords.  Adjust these values to your needs.

    Const minLength = 6

    Const maxLength = 20

    

    Dim X, Y, strPW

    

    If myLength = 0 Then

     Randomize

     myLength = Int((maxLength * Rnd) + minLength)

    End If

    

    For X = 1 To myLength

     'Randomize the type of this character

     Y = Int((3 * Rnd) + 1) '(1) Numeric, (2) Uppercase, (3) Lowercase

     

     Select Case Y

      Case 1

       'Numeric character

       Randomize

       strPW = strPW & CHR(Int((9 * Rnd) + 48))

      Case 2

       'Uppercase character

       Randomize

       strPW = strPW & CHR(Int((25 * Rnd) + 65))

      Case 3

       'Lowercase character

       Randomize

       strPW = strPW & CHR(Int((25 * Rnd) + 97))

     End Select

    Next

    RandomPW = LCase(strPW)

   End Function
