To generate upper/lower case characters or some symbols a coin flip can be used, heads capital, tails lower case. So, for example, a roll of 2 followed by a roll of 4 would select the letter "j" from the table below. The first die roll selects a row in the table and the second a column. One simple way to do this uses a 6 by 6 table of characters. Yet another method is to use physical devices such as dice to generate the randomness. #include #include #include int main ( void ) Mechanical methods
When a password policy enforces complex rules, it can be easier to use a password generator based on that set of rules than to manually create passwords.

Note that simply generating a password at random does not ensure the password is a strong password, because it is possible, although highly unlikely, to generate an easily guessed or cracked password.Ī password generator can be part of a password manager. A common recommendation is to use open source security tools where possible, since they allow independent checks on the quality of the methods used. While there are many examples of "random" password generator programs available on the Internet, generating randomness can be tricky and many programs do not generate random characters in a way that ensures strong security.
Random passwords can be generated manually, using simple sources of randomness such as dice or coins, or they can be generated using a computer. A random password generator is software program or hardware device that takes input from a random or pseudo-random number generator and automatically generates a password.
