Advanced Password Generator
Generate strong, memorable passwords from your own words. Adjustable strength, crack-time estimates, 100% in your browser.
–What is a password generator?
A password generator creates strong, random credentials in your browser. This tool offers three modes: Basic (random characters), Passphrase (memorable word chains), and Advanced (your own words transformed with leet, symbols, and crack-time analysis via zxcvbn).
Use Basic or Passphrase for quick one-offs; use Advanced when you want memorable base words with adjustable strength. Always store unique passwords in a password manager and enable two-factor authentication where available.
Everyday examples
New SaaS signup
Basic tab, 16 chars, all sets checked - copy into your password manager.
Guest WiFi
Passphrase tab, 4 words, hyphen separator - easy to read aloud to visitors.
Work laptop
Advanced tab, your words at strength 4 with symbols for corporate policy.
Banking app
Advanced strength 5 with neutral words, not personal names.
Family tablet
Passphrase with capitalize + trailing digit - kids remember the story.
API key seed
Basic at 32+ chars or Advanced max strength - store once in a secrets vault.
How to use
Pick a tab: Basic for random strings, Passphrase for word chains, Advanced for your own words with leet and crack-time estimates. Everything runs locally in your browser.
When should you use this?
Quick random passwords
Basic mode when you need length and charset rules fast.
Memorable passphrases
Passphrase mode for WiFi labels or spoken guest access.
Security awareness
Advanced mode compares your password to typical 8-char and strong 16-char benchmarks.
Common mistakes
Reusing one password
Generate a unique password per site - never recycle the same string.
Skipping a password manager
Even strong passphrases belong in Bitwarden, 1Password, etc.
Personal words only
Pet names and birthdays help targeted attacks - prefer unrelated words in Advanced mode.
| Mode / level | What you get | Best for |
|---|---|---|
| Basic | Random chars, length 8-64 | One-off accounts, strict charset rules |
| Passphrase | EFF word list, custom separator | WiFi, spoken guest access, managers |
| Advanced 1-2 | Your words + light symbols/digits | Low-risk, easy to recall |
| Advanced 3 | Your words + leet + digits between words | Everyday logins (recommended) |
| Advanced 4-5 | Aggressive leet + mixed case | Banking, admin, primary email |
Key password terms
Entropy
A measure of guessability. Higher entropy (more bits) means more combinations an attacker must try.
Passphrase
A password made of several random words. Often easier to remember than random symbols if the words are unrelated.
zxcvbn
A strength model that estimates crack time from patterns, not just length. Used in Advanced mode for benchmarks.
Leet speak
Substituting letters with similar-looking digits (e.g. a→4, e→3). Adds complexity but can still be guessed if the base word is common.
Frequently Asked Questions
Security, privacy, and how our password generator works.
Are my words or passwords sent to a server?
No. All three modes run entirely in your browser with JavaScript. AnyServ never receives your words or generated passwords.
Which tab should I use?
Basic: fully random strings with chosen length and character sets. Passphrase: memorable word chains from an embedded EFF word list. Advanced: transform your own words with adjustable strength and zxcvbn crack-time comparison.
How accurate are crack-time estimates?
Advanced mode uses the zxcvbn model with standard online/offline attack rates. They show relative strength - real attackers may differ.
Should I include personal names or pets?
Avoid them in Advanced mode - targeted attacks know biographical details. Prefer unrelated memorable words or use Basic/Passphrase for randomness.
Can I regenerate with the same settings?
Yes. Regenerate creates a new random outcome (characters, words, leet, separators) while keeping your current options.
About these results
Passwords are generated client-side for convenience. Strength estimates are educational, not a guarantee against breach or policy compliance. AnyServ is not responsible for account lockouts, rejected passwords, or security incidents - verify requirements with each service and use a reputable password manager.
