About this strong password generator
A strong password generator goes beyond basic randomness: one click gives you a maximum-strength password from battle-tested presets, or a passphrase of real words you can actually remember. Choose “Maximum (64 chars)”, “Strong (32 chars)”, or “Readable (no ambiguous)” for hand-typed passwords — then click “Generate strong password”.
Most accounts fall to password reuse and brute-force guessing, not clever hacking. A 64-character password from the full printable set carries over 400 bits of entropy — no computer that will ever exist can guess it. A 5-word passphrase from a 7,776-word list still carries about 65 bits: strong enough for daily use and far easier to recall. Everything is generated locally in your browser — nothing is transmitted, stored, or seen by us.
How to use it
- For a random password, pick a preset: "Maximum (64 chars)" for the strongest possible, "Strong (32 chars)" for everyday balance, or "Readable (no ambiguous)" to exclude lookalikes like O/0 and l/1.
- Click "Generate strong password" to create it instantly — click again for a fresh one.
- For a passphrase instead, pick a word count from the select — "4 words", "5 words", or "6 words" — then click "Generate passphrase".
- Read the "Entropy: N bits" readout to see the estimated strength of what was generated.
- Click "Copy" to copy your password or passphrase to the clipboard.
The method behind it
Frequently asked questions
How is this different from the Random Password Generator?
The Random Password Generator gives full manual control — length slider, character-set checkboxes, and a strength meter. This page is the fast lane: one-click presets ("Maximum (64 chars)", "Strong (32 chars)", "Readable (no ambiguous)") plus word passphrases, with a single "Entropy: N bits" readout. Use this one for the strongest option with zero decisions; the other to tune every detail.
Are passphrases really secure?
Yes, if the words are truly random — which is exactly what this tool does. Each word is picked independently from a 7,776-word list, so a 5-word passphrase holds about 65 bits — far beyond brute force. What makes passphrases weak is humans picking them: a random draw like "cable-donut-ivory-plaza" is strong, but your favorite quote is guessable.
Which preset should I choose?
"Maximum (64 chars)" whenever a site accepts it — especially password-manager vaults, where you never type it. "Strong (32 chars)" for everyday accounts where older sites cap length. "Readable (no ambiguous)" when you must read it off a screen and type it by hand, like a guest Wi-Fi password. When in doubt, longer beats shorter.
Can this website see the passwords I generate?
No. Generation happens entirely inside your browser using the Web Crypto API. The password never leaves your device — not sent to our servers, not logged, not stored. Close the tab and it is gone except where you pasted or saved it.
Worked example
Compare three outputs. "Maximum (64 chars)": 94⁶⁴ combinations ≈ 419 bits. "Strong (32 chars)": 94³² ≈ 210 bits. A 5-word passphrase: 7776⁵ ≈ 2.8 × 10¹⁹ combinations ≈ 65 bits. At a billion guesses per second, the passphrase takes about 900 years to crack; the 64-char password, about 10¹¹⁰ years. The lesson: passphrases trade a sliver of theoretical strength for real memorability — and both are so far beyond brute force that the difference never matters.
