On Internet where every thing is networked, it is the password that provides you security from unwanted access to your email, computer account, online banking, and even for the security reason, your password in itself should be strong enough not be cracked by anyone else.

As for the strength of a password as long it as secure it is. To keep a password with top level security there come a number of password generators that provides you with reliable passwords. These generators work on three basic principles for password generation, length, randomness and trust. Despite with the above said criteria the best method to generate password is open-source generator on the computer mostly running Linux.  Below are discussed some of the best password generators:

Perfect Passwords: Offered by noted programmer Steve Gibson, Perfect Passwords generator uses algorithm with the highest level of entropy. While setting a password GRC server and your computer is secured by a SSL connection on Perfect passwords when it generates three strings at a time for generating password. Strings are 64 random hexadecimal characters (0-9 and A-F), 63 random printable ASCII characters, 63 random alpha-numeric characters (a-z, A-Z, 0-9). You can use a single string or combination of all strings to generate a password as below:

“4q){4′{y]SWt]796Ay|9=

PCTools: This provides various options for generating password counting upon length, punctuation, number; letters etc under SSL secured connection. Though it provides freeware, it is not open source and technical details are not provided over here.

GoodPassword: It provides random passwords with customization features and a “Leet” generator.

Multicians: It produces ten “pronounceable” passwords applying a Java applet and is not open source but code can be inspected and has not any SSL connection.

For Linux: And for Linux users, they can use following command to generate password.

% dd if=/dev/urandom count=1 2> /dev/null | uuencode -m - | sed -ne 2p | cut -c-8v1/oVN+S
