Generate Strong Passwords Online
This free password generator creates strong, random passwords to your specification. Choose the length and which character types to include — uppercase, lowercase, numbers, and symbols — then press Generate. Passwords are created in your browser using a cryptographically secure random source and are never sent anywhere, so they are safe to use for real accounts.
How to Use the Password Generator
- Set the password length (longer is stronger; 16+ is recommended).
- Tick the character types you want to include.
- Press Generate and copy your password.
What Makes a Password Strong
Password strength comes from two things: length and randomness. A long password drawn from a large character set has so many possible combinations that brute-force guessing becomes impractical. Adding uppercase, lowercase, numbers, and symbols enlarges the pool of characters, and true randomness means there is no pattern for an attacker to exploit. A 16-character random password mixing all four types is vastly stronger than a longer but predictable phrase based on dictionary words or personal information.
Why Use a Generated Password?
People are bad at inventing random passwords — we reuse them, base them on names and dates, and follow predictable patterns that attackers know well. A generated password has none of that structure, so it resists both guessing and dictionary attacks. The best practice is to use a unique generated password for every account and store them in a password manager, so a breach of one site never exposes the others. This tool gives you the strong, unique passwords; a password manager remembers them for you.
Generated Securely in Your Browser
This generator uses your browser’s cryptographic random number generator (the same class of source used for security keys), not a predictable function, so the output is genuinely unpredictable. Crucially, the password is created entirely on your device and is never transmitted to any server or logged anywhere — you can even disconnect from the internet and it still works. That makes it safe to generate passwords for your most important accounts.
Tips for Password Security
Use at least 16 characters where a site allows it, include all four character types, and never reuse a password across sites. Pair generated passwords with a reputable password manager and enable two-factor authentication on important accounts for an extra layer of protection. Avoid substituting numbers for letters in common words (like “p4ssw0rd”) — attackers account for those tricks. True randomness, which this tool provides, is what actually keeps you safe.
Frequently Asked Questions
How long should a password be?
At least 12 characters, and 16 or more for important accounts. Longer is stronger.
Are the generated passwords safe?
Yes — they are created with a cryptographically secure random source entirely in your browser and never sent anywhere.
Is the password generator free and private?
Yes — it is free, needs no signup, and runs entirely in your browser.
Passphrases, Managers, and Real Security
The single biggest improvement most people can make to their security is to stop reusing passwords. When one site is breached — which happens constantly — attackers take the leaked email-and-password pairs and try them everywhere else, a tactic called credential stuffing. A unique, generated password for every account means a breach of one site cannot unlock the others. The practical way to manage dozens of unique passwords is a reputable password manager, which stores them encrypted and fills them in for you, so you only need to remember one strong master password.
Length beats complexity tricks. A long password from a large random character set is stronger than a short one peppered with symbols, and far stronger than a clever-looking substitution like swapping letters for numbers, which attackers anticipate. Where a site imposes a low character limit, max it out and include all character types; where it allows long passwords, use 20 or more characters. Finally, enable two-factor authentication on important accounts so that even a leaked password is not enough to get in. This generator gives you the strong, unique, truly random passwords that all of this advice depends on, created and kept entirely on your own device.
