Password Generator
Create strong random passwords and memorable passphrases — generated locally, never sent anywhere.
Generate a strong random password in one click, or switch to passphrase mode for a string of random words that is easy to type and remember. Choose the length, mix of lowercase, uppercase, digits, and symbols, and optionally exclude look-alike characters (0, O, 1, l, I) that cause typos on paper and over the phone.
Every password is created with your browser’s cryptographically secure random number generator — the same class of randomness used by password managers — and a live entropy meter shows exactly how strong it is. Use it for new accounts, Wi-Fi keys, database credentials, or one-time shares, and generate five at a time when you are provisioning several accounts at once.
How to generate a strong password
- 1
Pick a length (12+ recommended) and select the character sets you want — or switch to passphrase mode for random words.
- 2
Click generate and check the strength meter; regenerate until you like the result, or generate five at once.
- 3
Copy the password and save it straight into your password manager.
Why use Nofolo’s password generator?
Cryptographically secure
Uses crypto.getRandomValues with unbiased rejection sampling — never Math.random(), never predictable.
Passphrase mode
Random-word passphrases (3–8 words) with your choice of separator and capitalization — strong and memorable.
Live strength meter
Entropy in bits with a Weak / Fair / Strong / Excellent rating, so you know exactly what you are getting.
Exclude ambiguous characters
One toggle removes 0, O, 1, l, I, and | — perfect for passwords that get read aloud or written down.
Guaranteed character mix
Every password contains at least one character from each set you select, so it passes strict signup rules.
Private by design
Generated entirely in your browser. Nothing is transmitted, logged, or stored — ever.
Frequently asked questions
Is it safe to generate a password online?
Here, yes. Passwords are generated locally in your browser with crypto.getRandomValues — a cryptographically secure random source — and are never transmitted, stored, or logged. You can disconnect from the internet after the page loads and the generator keeps working.
How long should my password be?
At least 12 characters with mixed character sets — 16 is a comfortable default that reaches "Excellent" strength (80+ bits of entropy). For anything protecting money or email, longer is always better, and unique per site matters more than anything.
Are passphrases really secure?
Yes — security comes from the number of words, not from looking complicated. Each random word adds roughly 7.6 bits of entropy from this word list, so 6–8 words rivals a long random password while being far easier to type and remember.
What does the strength meter measure?
Entropy in bits: password length × log2(size of the character set). Below 45 bits is Weak, 45–59 Fair, 60–79 Strong, and 80+ Excellent — a scale in line with common security guidance for offline-attack resistance.
Why exclude ambiguous characters?
Characters like 0/O and 1/l/I look identical in many fonts. If a password will ever be read aloud, printed, or typed from paper — Wi-Fi keys, temporary credentials — excluding them prevents frustrating lockouts at a tiny cost in entropy.
