Question: Why Longer Passwords Are Harder To Break?

Why are longer passwords better?

Longer passwords are better.

It is always easier to increase password combinations when increasing the power, not the base, of the exponential function.

The first idea is to require numbers and special characters in the password but keep the length at eight.

Does password length play a role in increasing the strength of the password?

Character-for-character, password length is more important for security than complexity. Requiring complexity but allowing passwords to remain short makes passwords more vulnerable to attack than simply requiring easier-to-remember, longer passwords.

How long does it take to crack an 8 character password?

So, to break an 8 character password, it will take (1.7*10^-6 * 52^8) seconds / 2, or 1.44 years. Note that on a GPU, this would only take about 5 days. On a supercomputer or botnet, this would take 7.6 minutes. As you can see, simply using lowercase and uppercase characters is not enough.

Why do special characters make passwords difficult to crack?

The reason has everything to do with password entropy: a representation of how much uncertainty there is in a password. This translates to how computationally difficult a password is to crack. Simply put, adding length increases entropy more efficiently than replacing letters with symbols.

How long should my password be secure?

1. Think Length, Not Complexity. “A longer password is usually better than a more random password,” says Mark Burnett, author of Perfect Passwords, “as long as the password is at least 12-15 characters long.”
