How to Use the Password Generator
- Set your desired password length with the slider (16+ recommended).
- Choose whether to include numbers and symbols.
- Click 'Generate New' for a fresh cryptographically-random password.
- Copy it and store it in a password manager.
Why Use Our Password Generator?
- Crypto-grade randomness — uses your browser's secure random number generator, not Math.random.
- Entropy readout — see the actual bits of security, not a vague 'strong' label.
- Up to 64 characters — for passphrases and high-security accounts.
- Never transmitted — generated locally; we couldn't see your password if we wanted to.
Common Use Cases
- New account signups: Generate a unique password per site so one breach can't cascade into your other accounts.
- Wi-Fi passwords: Create long random strings you only type once per device — set it and forget it.
- Developers: Mint API keys, tokens, salts, and test credentials with real cryptographic randomness.
- Shared family or team accounts: Generate neutral, strong passwords for accounts several people need to access.
- Post-breach rotation: Bulk-generate replacements when a breach notification tells you to change a password.
Password Generator vs Alternatives
- Password-manager generators (1Password, Bitwarden): Convenient and auto-saved — if you already use a manager, generating inside it is the smoothest workflow. Our page needs no install or account and shows you the exact entropy in bits, which most managers hide.
- Memorable passphrases: Easier to type on TVs, game consoles, and phones, but lower entropy per character. Use a passphrase where typing matters; use this generator at 20+ characters everywhere else.
- Human-invented passwords: Patterns like 'Summer2024!' fall to dictionary and rule-based attacks in seconds. Random generation has no patterns to exploit — that's the entire security advantage.
Bottom line: the gold standard is a password manager holding a unique generated password per site. This page is the fastest way to create one of those passwords without installing anything.
Frequently Asked Questions
How long should my password be?
At least 16 characters for important accounts. Every extra character multiplies the guessing effort enormously.
Are generated passwords truly random?
Yes — the tool uses the Web Crypto API's secure random generator, the same primitive browsers use for TLS.
Should I use the same password everywhere?
Never. Use a unique generated password per site and store them in a reputable password manager.
Do you store my passwords?
No. Generation happens in your browser and nothing is sent or saved anywhere.
What is password entropy?
A measure of unpredictability in bits. 80+ bits is effectively uncrackable by brute force with current technology.
Is it safe to use an online password generator?
It depends on where the password is created. This generator runs entirely in your browser using the Web Crypto API — nothing travels over the network, so no one can intercept or log it. As a rule, never use a generator that sends your password to a server or requires an account to generate one.
How long should a password be in 2026?
At least 16 characters for important accounts. A 16-character password from this generator's full character set carries about 102 bits of entropy — far beyond brute-force reach with any current technology.
What is the difference between a password and a passphrase?
A passphrase is several random words strung together ('correct horse battery staple' style). Passphrases are easier to type and remember but carry less entropy per character than a random string. Both beat any human-invented password; use random strings when typing isn't a concern.
How long would it take to crack a 16-character generated password?
Effectively never by brute force — 84¹⁶ combinations would take hundreds of billions of years even for supercomputers. Real account takeovers happen through phishing, password reuse, and database leaks, not brute force — which is why a unique password per site matters more than extra length.
Should I change my passwords regularly?
No. Current NIST guidance says forced rotation pushes people toward weaker, predictable passwords. Change a password only when there's evidence it's been compromised, and use a unique generated password for every site instead.
Can I generate a password without symbols?
Yes — uncheck 'Symbols' (and 'Numbers' if you like). Some older sites, routers, and Wi-Fi setups reject special characters; a longer letters-only password still carries strong entropy.
