That's tough slogging for a brute-force cracking attack, and brute-force guessing is really the only way to crack a truly random password. If you choose an eight-character password, the number of possibilities is 80 to the eighth power, or 1,677,721,600,000,000-more than a quadrillion. In a totally random password, there are 80 possibilities for every character. That makes a nice round total of 80 characters to choose from. For simplicity, let's say there are 18 special characters available. It also includes a collection of special characters that may vary from product to product. The pool of available characters includes 26 uppercase letters, 26 lowercase letters, and 10 digits.

You should always enable use of all available character sets, unless you're generating a password for a website that, say, doesn't allow special characters. Rather, they return a string of characters, using random numbers to choose from the available character sets. Of course, password generators don't literally return random numbers. But if it makes you happy, go for it! Password Managers Reduce Randomness The screenshot above shows Password Depot's matrix-style randomizer yes, the characters drop as you move your mouse.ĭo you really need to add real-world randomization? Probably not. Among those that offer this real-world randomization are AceBIT Password Depot, KeePass, and Steganos Password Manager. By incorporating your own mouse movements or random characters into the random algorithm, they obtain a truly random result. Fortunately, you're almost certainly not the target for this kind of cyberespionage.Įven so, a few password managers actively work to eliminate even the remote possibility of such a focused attack. If you're the subject of such an attack, your security suite probably can't protect you. That sort of directed hacking is extraordinarily unlikely, except in a dedicated nation-state attack, or corporate espionage. Given that information and the seed, the hacker could conceivably replicate the sequence of random numbers (though it would be difficult). However, it's theoretically possible for a skilled hacker to determine the pseudo-random algorithm used. This is fine for everyday use, and fine for most people's password generation needs. If the seed was a 32-bit integer, that means the algorithm would run through 4,294,967,295 other numbers before a repeat. The original seed never turns up again until every other number has come up. The algorithm processes the seed and gets a new number with no traceable connection to the old, and the new number becomes the next seed. This algorithm starts with a number called a seed. Password managers and other computer programs use what's called a pseudo-random algorithm. Yes, there are a few random number sources based on radioactive decay (Opens in a new window), but you won't find these in the average consumer-side password manager. But in the computer realm, physical randomizers like dice aren't available. Nobody can predict whether you'll get snake eyes, boxcars, or a lucky seven. When you throw a pair of dice, you get a truly random result. When you know how they work, you can choose the one that's best for you, and use the one you have intelligently. However, not all password generators are created equal.

But don’t bother flailing at the keyboard to come up with those passwords-your password manager can help.Īlmost every password manager includes a password generator component, so you don't have to come up with those random passwords yourself.
#R random password generator upgrade
As time allows, you’ll upgrade your existing accounts with better passwords. For starters, you’ll use a long, strong, random password for every new account.
What you need is a password manager that will both store your passwords and improve their security. What do you do? Use your birthday, or your labradoodle’s name? Enter that favorite password you use everywhere? Poke randomly at the keyboard and hope you can remember that your password is m4i/enH? These are all bad ideas.
You’ve just created an account on a new secure site, and it asks you for a password.
