Your Password Is Probably Terrible. Here Is How to Fix That.
The most common passwords in the world are still “123456,” “password,” and “qwerty.” Tens of millions of people use these. Security researchers find them at the top of every leaked credential database, year after year, without fail.
But weak passwords are not just a problem for people using obvious choices. A password like “Summer2024!” looks strong to most people. It has uppercase, lowercase, a number, and a special character. It would pass most website password strength checkers. It would also be cracked in under three minutes by a modern password attack, because it follows a predictable pattern that attackers specifically target.
A genuinely strong password looks like this: K#9mP2$vXq7@nL4w
No words. No patterns. No personal information. Pure randomness. This tool generates passwords exactly like that — in one click.
—What Makes a Password Actually Strong
Password strength is measured by entropy — the mathematical unpredictability of the password. The higher the entropy, the more combinations an attacker needs to try before finding the right one.
Four factors determine entropy:
Length — The single most important factor. Each additional character multiplies the number of possible combinations. A 12-character password is not twice as strong as a 6-character password — it is exponentially stronger. Going from 8 to 16 characters is more impactful than any other single change you can make.
Character set size — Using only lowercase letters gives you 26 possible characters per position. Adding uppercase doubles it to 52. Adding numbers brings it to 62. Adding special characters brings it to approximately 95. Each expansion of the character set multiplies entropy.
Randomness — A password generated by a random process is fundamentally stronger than one invented by a human. Human-created passwords follow patterns — capital letters at the start, numbers at the end, common word substitutions like @ for a and 3 for e. Attackers know all of these patterns and use them to narrow their search. True random passwords have none of these patterns.
Uniqueness — Using the same password across multiple sites means one breach exposes all of them. A strong password used on ten sites is ten times more vulnerable than ten unique strong passwords.
—Password Length Guide — How Long Is Long Enough?
8 characters — The minimum many sites accept. Not recommended for anything important. Modern hardware can crack an 8-character random password in hours to days depending on the character set.
12 characters — Solid for most personal accounts. A 12-character random password using all character types would take centuries to crack by brute force with current technology.
16 characters — Recommended for important accounts — email, banking, primary social media. The added length makes brute-force attacks impractical with any foreseeable technology.
20+ characters — Use this for your password manager master password, root server access, cryptocurrency wallets, and any account where a breach would be catastrophic. The practical security at this length is essentially absolute.
—The Four Password Types This Generator Creates
Random Password
A completely random mix of uppercase letters, lowercase letters, numbers, and special characters. Maximum entropy. Impossible to memorize, which is intentional — you should be storing it in a password manager, not trying to remember it.
Memorable Password
A sequence of random words joined together — sometimes called a passphrase. “correct horse battery staple” is the famous example from the xkcd comic that introduced this concept to mainstream audiences. Four random common words create a password that is simultaneously long, high-entropy, and actually possible to remember for the accounts where memorization matters.
PIN
A numeric-only password for applications that require it — bank ATM PINs, phone unlock codes, and similar contexts where only numbers are accepted.
Custom
Configure exactly which character types to include, set a specific length, and exclude characters that are commonly confused with each other — 0 and O, 1 and l, for example — for use cases where the password needs to be typed rather than pasted.
—Why You Need a Password Manager
The only practical way to use strong, unique passwords for every account is a password manager. Without one, you are forced to choose between memorability and security — and memorability almost always wins, which means weak or reused passwords.
A password manager stores all your passwords in an encrypted vault that you unlock with one strong master password. You only need to remember one password. The manager handles everything else — generating, storing, and filling in unique strong passwords for every site.
Free options include Bitwarden, which is open-source and widely trusted. Paid options include 1Password and Dashlane. All major browsers also include built-in password managers that are significantly better than no manager at all.
The workflow is simple: use this tool to generate a strong password, copy it, paste it into both your new account and your password manager. You never need to see or type the password again.
—What to Avoid When Creating Passwords
Dictionary words — Any single word in any language is vulnerable to dictionary attacks that try every word in seconds.
Personal information — Names, birthdays, pet names, addresses, and phone numbers are the first things attackers try because they are often publicly available or easily guessable.
Keyboard patterns — qwerty, asdfgh, 123456, and similar sequences are in every attack dictionary.
Common substitutions — Replacing a with @, e with 3, i with 1, o with 0 is a pattern so well-known that attack dictionaries include all common substitution variants of dictionary words automatically.
Password recycling — Changing password1 to password2 to password3 is not creating new passwords. It is extending a known password pattern, which attackers explicitly test.
—Frequently Asked Questions
Are the passwords generated here stored anywhere?
No. All password generation happens in your browser using JavaScript. No password is ever sent to any server, logged, or stored anywhere. The moment you close the tab, the generated passwords are gone.
How random are the generated passwords?
The generator uses the browser’s built-in cryptographic random number generator — the same source of randomness used by security software and cryptographic applications. This is fundamentally different from the pseudo-random numbers used in most programming — it produces true cryptographic randomness suitable for security-critical applications.
Should I use a password generator for every account?
Yes, ideally. With a password manager, there is no practical reason to use a weak or reused password for any account. The only exception is the password manager’s master password itself — that one should be a memorable passphrase you can reliably remember and never store anywhere.
What special characters should I avoid?
Some websites do not accept all special characters. If you find a generated password is rejected, regenerate without special characters and compensate by increasing the length. A 20-character alphanumeric password is stronger than a 12-character password with special characters.
Is this tool free?
Yes, completely free with no account required.
—Generate. Copy. Store. Done.
Click generate. Copy the password. Paste it into your account and your password manager. That is the entire process. The strongest password you have ever used is one click away.
