Membership Generate Password alphanumeric only password?


How can I use Membership.GeneratePassword to return a password that ONLY contains alpha or numeric characters? The default method will only guarantee a minimum and not a maximum number of non alphanumeric passwords.


Solution

  • string newPassword = Membership.GeneratePassword(15, 0);
    newPassword = Regex.Replace(newPassword, @"[^a-zA-Z0-9]", m => "9" );
    

    This regular expression will replace all non alphanumeric characters with the numeric character 9.
