Why Strong Passwords Are Important
The majority of account breaches are not due to sophisticated hacking, but are instead due to weak, reused, and easily guessable passwords. (Ever wonder what passwords people are actually using? See our Top 100 Worst Passwords of 2026.) A strong password is your first and best line of defense when it comes to protecting your accounts from unauthorized access, including your email, online banking, social media, and even your coding tools.
Our tool utilizes the same standard as security experts and the browser's built-in crypto library to
create your password: the crypto.getRandomValues()
method. Your password is never transmitted to a server.
How Long Should a Password Be?
Experts suggest that the password length for regular accounts should be at least 16 characters and for accounts such as email or banking, it should be 20+ characters long. Length is more important than complexity; a 20-character lowercase password is much harder to crack than an 8-character password with special characters.
Should I Use a Password Manager?
Yes, absolutely! Create a unique and strong password for each account and store it with a good password manager like Bitwarden (free and open-source), 1Password, or your browser's built-in password manager. Never use the same password for multiple accounts; if the account is compromised, all accounts will be compromised too.
What Makes a Password Strong?
- Length is one of them. More characters mean a much longer time to crack, and exponentially so! Aim for 16 or more.
- Character type mix is also important. Mixing uppercase, lowercase, numbers, and symbols reduces the cracking space by orders of magnitude.
- Never use anything that could be considered personal info. This includes birthdays, names, and words found in any dictionary.
- Unique passwords for each site. One strong password is weaker if you use it for 10 sites, compared to 10 weaker, unique passwords for 10 sites.
Frequently Asked Questions
How do I use the password generator?
Well, all you have to do is click "Generate Password" and instantly, a strong random password appears. You can also change the password length by adjusting the slider. You can also turn the character type options on or off to suit your needs. Once you're done, all you have to do is click "Copy" and then paste it in the password box. That's it.
Is my password sent to your server?
Absolutely not. The password generation process happens entirely within your browser using the Web Crypto API, crypto.getRandomValues(). We're not even involved. You can even turn off your internet connection after loading the page and it will work just fine.
What's a passphrase and when do I need to use it?
A passphrase is a string of random everyday words, e.g., "maple-comet-oxygen-relay". It's a long string of words like a password but is surprisingly secure due to its length and yet easy to remember and type. Use a passphrase for accounts that need to be typed in manually from time to time, e.g., your device's login password or your password manager's master password.
How often do I need to change my passwords?
According to the current security guidelines provided by NIST and Microsoft, passwords should only be changed if there is a sign of a breach. However, forcing password rotations could lead users to use weaker passwords. Nevertheless, never use the same password for different sites.
How is the "Crack Time" estimated?
We use the industry-standard zxcvbn library (originally developed by Dropbox) to estimate password strength. Unlike simple calculators that only count characters, our tool analyzes patterns, common phrases, and dictionary words. Our crack time represents a conservative offline attack (10,000 guesses/second), which is the global security standard for evaluating password resilience against modern cracking tools.
What wordlist do you use for passphrases?
We use the complete EFF 7,776-word long wordlist. Each word is specifically chosen for being easy to remember while providing maximum mathematical randomness (entropy). A 5-word passphrase using this list is significantly more secure against modern cracking hardware than even complex 10-character passwords.
Is it safe to trust a free password generator?
In this case, yes, since nothing is being transmitted outside your browser. We utilize zxcvbn.js and the Web Crypto API locally. You can even turn off your internet connection after loading the page and it will work just fine. We recommend HandleKit precisely because it operates entirely on the client-side, eliminating any "man-in-the-middle" risk.
