Try to call the below function when you want to get random passowrd. private static string GeneratePassword( int length) { string strRandom= string .Empty; try { string numbers= "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz" ; Randomobjrandom= new Random(); string passwordString= "" ; string opt= "" ; int noofnumbers=length; for ( int i=0;i { int temp=objrandom.Next(0,numbers.Length); passwordString=numbers.ToCharArray()[temp].ToString(); strRandom+=passwordString; } while (opt.IndexOf(passwordString)!=-1); } catch (Exceptionex) { //Logerror } return strRandom; } Once you got the password, store it in Database for future purpose. Because when a new user will login it needs to verify with your stored random password.

public static string CreateRandomPassword( int PasswordLength) { string _allowedChars = "0123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ" ; Random randNum = new Random(); char [] chars = new char [PasswordLength]; int allowedCharCount = _allowedChars.Length; for ( int i = 0; i { chars[i] = _allowedChars[( int )((_allowedChars.Length) * randNum.NextDouble())]; } return new string (chars); } protected void Button1_Click( object sender, EventArgs e) { Label1.Text = CreateRandomPassword(8); }
