Introduction:

Sometimes we need to generate random passwords for users. In this small article we will see two techniques that will generate unique passwords.

Using GUID:

The first method of Generating unique password is by using the System.Guid class.

Making custom method to Generate Unique Passwords:

If you want to make your own custom method that generates random passwords than you can use the method below:

string alphabets = "abcdefghijklmnopqrstuvwxyz";
string numbers = "01234567890123456789012345";
StringBuilder password = new StringBuilder();
Random r = new Random();
for(int j=0; j<=20;j++)
{
for(int i=0;i<=5;i++)
{
password.Append(alphabets[r.Next(alphabets.Length)]);
password.Append(numbers[r.Next(numbers.Length)]);
}
Response.Write(password.ToString());
password.Remove(0,password.Length);

}

The above method will generate passwords which will be the combination of alphabets and numbers.
