Selected character types are injected into the passphrase for added security.
How to Use This Password Generator?
Using our free password generator is instant and requires no sign-up. Choose one of three modes using the tabs at the top of the tool, then click Generate Password to create a strong, cryptographically secure password in milliseconds.
In Password mode, drag the length slider anywhere between 6 and 64 characters. Tick the character type checkboxes – Uppercase (A-Z), Lowercase (a-z), Numbers (0-9), and Symbols (!@#$%^&*) – to control exactly what goes into your password. The Password Strength bar updates live, showing Weak, Fair, Good, or Strong as you adjust your settings.
In Memorable mode, the tool strings together random English words separated by your chosen delimiter – hyphen, dot, underscore, or space. You can set the word count from 3 to 8, capitalise each word, append two random digits, and inject uppercase letters, numbers, or symbols directly into the passphrase for extra strength. The result is a password that is both highly secure and easy to remember – ideal for master passwords or account credentials you type regularly.
In 5 Passwords mode, the generator instantly produces five unique random passwords in one click. Adjust the length and character types, then hit Regenerate All to refresh the entire list. Click Copy on any individual row to copy that password to your clipboard, or hit Copy All to grab all five at once – useful when setting up multiple accounts in one session.
Once you have a password you like, click the Copy button next to the output field. A confirmation message appears immediately. The tool works on every device – desktop, tablet, and mobile – and processes everything locally in your browser. Nothing is ever sent to a server.
What is a Password Generator?
A password generator is a free online tool that automatically creates random, strong passwords using a combination of characters that would be impossible to guess by hand. Instead of reusing a pet’s name or a favourite word – habits that make accounts dangerously easy to compromise – a password generator produces a unique, unpredictable string every time you click Generate.
Our random password generator uses the browser’s built-in Web Crypto API (window.crypto.getRandomValues) to source true cryptographic randomness. This is the same standard used by security-focused software and is fundamentally stronger than Math.random(), which many other online tools rely on. Every character is chosen from a guaranteed-random pool, making brute-force and dictionary attacks statistically impossible against a password of 16 or more characters.
Whether you need a secure password for a new social media account, a unique passphrase for your password manager, or a batch of credentials while setting up a team’s software accounts, this tool handles it all – entirely in your browser, with no downloads, no extensions, and no account required.
Why Does Password Strength Matter?
Weak passwords are the single most common entry point for account breaches. Attackers use automated tools that can test billions of password combinations per second against leaked credential databases. A short, predictable password like john1990 or qwerty123 can be cracked in under a second. A truly random 16-character password with mixed character types would take thousands of years to crack using the same hardware.
The most important principles of a strong password are length, randomness, and uniqueness. Length matters because each added character multiplies the number of possible combinations exponentially. Randomness matters because patterns – keyboard walks, dictionary words, predictable substitutions like @ for a – are all built into cracking dictionaries. Uniqueness matters because when one site suffers a data breach, attackers immediately test those credentials against every other major platform. A password reused across three sites means one breach becomes three.
A strong password generator removes all the guesswork. Pair it with a reputable password manager like Bitwarden, 1Password, or Dashlane, so you only ever need to remember one master passphrase – and let the generator create uncrackable, unique credentials for every account you own.
For accounts you access frequently and must memorise – such as your password manager’s master password or a work login – use the Memorable mode. A passphrase like Coral-River-Spark-71 with injected uppercase and symbol characters is statistically stronger than most random 10-character passwords, far easier to type from memory, and impossible to guess.
Common Uses of a Secure Password Generator
People use a secure password generator in a wide range of everyday situations: creating unique login credentials for every new website and app they join; setting a strong master password for a password manager such as Bitwarden or LastPass; generating API keys and access tokens during software development; creating secure Wi-Fi passwords for home or office networks; producing random passphrases for encrypted drives or ZIP archives; resetting compromised passwords quickly after a data breach notification; setting up multiple employee accounts with different strong passwords in a single session using the 5 Passwords mode; and creating memorable yet highly secure passphrases for accounts accessed daily without a password manager.
IT professionals and developers use it to rapidly generate test credentials, seed dummy accounts, or create service passwords without any risk of pattern or reuse. Security-conscious individuals use it as a habit – generating a fresh password for every account sign-up so their credential footprint is always unique and breach-resilient.
Frequently Asked Questions
Is this password generator truly random and secure?
Yes. The tool uses window.crypto.getRandomValues() – the Web Crypto API built into every modern browser – which produces cryptographically secure random numbers. This is the same standard used by security software, operating systems, and encryption libraries. It is fundamentally stronger than JavaScript’s Math.random(), which is not considered cryptographically secure and should never be used for passwords.
Are my passwords sent to a server or stored anywhere?
No. Every password is generated entirely inside your browser using local JavaScript. Nothing is transmitted to any server – there are no network requests, no logs, no analytics tied to your generated passwords. Once you close or refresh the page, the generated passwords are gone. This makes the tool completely private by design.
How long should my password be?
For most online accounts, a minimum of 16 characters is recommended. For highly sensitive accounts – banking, email, password managers – aim for 20 characters or more. The strength meter in this tool turns Strong at 16+ characters with mixed character types. If you prefer a passphrase, four or more words in Memorable mode produces an equivalent or greater level of security while remaining memorable.
What is the difference between a password and a passphrase?
A password is a short, dense string of random characters – for example kT#9mLqZ$2vW. A passphrase is a longer string of random words – for example Coral-River-Spark-71!. Passphrases are generally easier to type and remember, while being statistically as strong or stronger than a shorter random password, thanks to their length. Use the Memorable tab to generate passphrases with optional injected numbers and symbols for added entropy.
Should I include symbols in my password?
Including symbols increases the character pool from 62 to 90+ possible values per position, which multiplies the total number of combinations and makes brute-force attacks significantly harder. However, some websites restrict which symbols they accept. If a site rejects your generated password, uncheck Symbols and regenerate – a 20-character password with uppercase, lowercase, and numbers is still extremely strong.
Can I use this tool to generate multiple passwords at once?
Yes. Switch to the 5 Passwords tab to generate five unique passwords simultaneously. You can set the length and character types, then click Regenerate All to get a fresh batch. Each row has its own Copy button, and the Copy All button copies all five passwords to your clipboard as a list – ideal for setting up multiple accounts or sharing credentials with a team.
Does this tool work on mobile devices?
Yes. The password generator is fully responsive and touch-optimised. The sliders, checkboxes, tabs, and copy buttons all work reliably on smartphones and tablets across iOS and Android. The Copy button uses the modern Clipboard API with a fallback for older mobile browsers, so copying works in every environment.
How do I remember a generated password?
You don’t have to. The best practice is to store all your generated passwords inside a password manager — Bitwarden (free and open-source), 1Password, or Dashlane are widely recommended. You only need to remember one strong master passphrase to unlock the manager. For credentials you genuinely must memorise, use the Memorable mode to generate a multi-word passphrase that is both strong and human-readable.
