Why a Passphrase is better than a Password?
Passphrases offer several advantages over traditional passwords.
Passphrases are longer than passwords but easier to remember. For example a simple passphrase like “correct horse battery staple” has more entropy (randomness) than a complex password like “P@ssw0rd123!” while being much easier to memorize.
Also, because length beats complexity, the security of an authentication system is primarily determined by the total number of possible combinations an attacker must try.
And because human brains are designed to remember stories and phrases, not random characters, passphrases are the better choice. So you can and you should use a unique passphrase for each one of your accounts.
How a Passphrase is generated?
All the passphrases generated here are actually generated locally on your device’s browser, using a cryptographically secure algorithm for generating random values.
It is important to know that we don’t store or have access to any of the passphrases generated here, so this page is safe to use.
This passphrase generator uses the cryptographically secure window.crypto.getRandomValues() API for generating random values in your browser. More details here about the getRandomValues() method.
However you should be aware that nothing is 100% secure and this method of generating passphrases it’s only as secure as the underlying operating system’s implementation. It could potentially be compromised if the user’s device is compromised or
in older or specific browser implementations, there might be edge cases where the randomness quality is reduced.
Also the browser’s random generator might be affected by virtualization in some environments.
Is a 3 word passphrase secure?
A 3 (three) word passphrase is not secure enough.
Using our generator the 3 word passphrase Impressed-Article-Seek-44<( has an estimated entropy of 55 bits and an estimated time to crack of just 20 days and its strength is considered weak. Please note that special characters were also added to this passphrase but it is still easy to crack.
However a 4 word passphrase with two special characters added has an estimated entropy of 68 bits and an estimated time to crack of 400 years. For this reason its strength is considered moderate.
A 5 word passphrase with two special characters added has an estimated entropy of 82 bits and an estimated time to crack of millions of years.
A 6 word passphrase (the default setting for our passphrase generator) with two special characters added has an estimated entropy of 95 bits and an estimated time to crack of millions of years. So this option represents a good balance between the number of words and the provided security and its strength is considered strong.
To be on the extremely safe side you may generate a passphrase that contains more than 6 words with an estimated entropy of over 100 bits. In this case its strength is considered very strong.
Entropy in bits is a measure of unpredictability or randomness, used mostly in cryptography and information theory to quantify the strength of passwords or passphrases. In this context, it tells you how many possible combinations exist and how hard it is to guess the correct one.
How to check if your email or password / passphrase were exposed?
Periodically you should check your email(s) and all your passwords or passphrases to find out if they were exposed in a data breach.
There are two reputable tools to achieve this:
Have I Been Pwned provides great tools to check if your email was exposed or if your password / passphrase was exposed in a data breach.
Mozilla Monitor is another great tool to find where your private info is exposed. You can find more details here: monitor.mozilla.org
What is password or passphrase recycling?
Password recycling is the practice of reusing the same password or passphrase (or very similar ones) across multiple websites or accounts.
Usually people do this because it’s easier to remember just one or two passwords / passphrases and they may not realize all the risks involved.
So if If a hacker gets your password or passphrase from a weak or breached site, they can try it on other services, like your email, bank, or social media. Also hackers use automated tools to test known email / password or passphrase pairs on hundreds of websites.
So the best thing is to have a unique and memorable passphrase for each one of your important accounts. So go ahead and use our free passphrase generator right now!
Should I use a Password Manager?
Password managers are generally very safe and are widely recommended by security professionals. But like any tool, their safety depends on how they’re used and which provider you choose.
Your data is encrypted on your device, meaning even the password manager company can’t read your passwords.
The most used password managers (e.g., Bitwarden, 1Password) use this approach and only you know your master password.
Also most password managers support 2FA, which greatly reduces the risk even if your master password is compromised.
However if someone gets your master password and 2FA isn’t enabled, they could access everything stored in your password manager.
Also if your device is infected with keyloggers or you’re tricked into entering your master password on a fake site, the manager can’t protect you.
So at least for your password manager you should use and generate a secure and memorable passphrase.
