Password Generator
Generate strong, secure passwords instantly. Nothing is stored.
Character Types
Quick Presets
Password strength comes overwhelmingly from length and randomness, not from satisfying arbitrary complexity rules. A 16-character password mixing letters, numbers, and symbols is dramatically harder to crack than an 8-character password with one forced special character — even though the shorter one technically checks more boxes on a typical signup form.
This generator produces passwords using your browser's cryptographic random number source, avoiding the predictable patterns — substituting '3' for 'e', appending '123' — that humans tend to fall into when creating passwords manually, patterns that automated cracking tools are specifically built to try first.
You can adjust length and which character types to include, letting you match a specific site's requirements while keeping the underlying randomness intact.
The math behind password strength is worth understanding briefly: each additional character multiplies the number of possible combinations an attacker would need to try, while each additional allowed character type (adding numbers to letters-only, say) only multiplies it once. That's why length consistently outperforms complexity rules in actual cracking-resistance calculations, even though complexity rules are what most signup forms enforce.
It's also worth distinguishing between offline and online cracking scenarios. A weak password on a site with no rate-limiting can be tried thousands of times per second; the same password on a site that locks out after five failed attempts is far more protected regardless of the password's inherent strength. Strong passwords remain important because you can't control how well any given site defends against offline attacks on a leaked password database.
It's worth understanding why password managers specifically pair so well with a generator like this one: since a password manager remembers the password for you, there's no longer any practical reason to choose a memorable-but-weaker password over a maximally random, strong one — the usual trade-off between memorability and security effectively disappears once you're not relying on your own memory.
Step-by-step instructions
- 1
Set your desired length
Longer passwords are stronger; 16+ characters is a reasonable default.
- 2
Choose character types
Toggle uppercase, lowercase, numbers, and symbols on or off as needed.
- 3
Generate a password
Click generate to produce a new random password instantly.
- 4
Copy and store it securely
Copy the password directly into a password manager rather than a plain text note.
Common use cases
Creating new account passwords
Generate a strong, unique password for every new signup instead of reusing an old one.
Rotating compromised credentials
Quickly generate a fresh password after a service reports a data breach.
Shared team accounts
Create a strong password for shared logins that need to be distributed securely.
Wi-Fi and device passwords
Generate a strong passphrase for router admin panels or device setup.
Generating recovery codes and API keys
Create long, random strings suitable as backup recovery codes or placeholder API keys during development.
Tips for best results
- Aim for at least 12-16 characters for anything important; length matters more than symbol variety alone.
- Never reuse the same strong password across multiple sites — one breach then exposes every account using it.
- Store generated passwords in a password manager rather than memorizing or writing them down.
- Include all character types (upper, lower, number, symbol) unless a specific site restricts certain characters.
- Length contributes more to real cracking-resistance than character variety — a longer password with fewer symbol types often beats a shorter one packed with special characters.
- Enable two-factor authentication wherever it's offered, since it protects your account even in the rare case a strong password is somehow compromised.
Frequently asked questions
Is it safe to generate passwords in a browser?
Yes — generation happens locally using your browser's cryptographic random functions, and the password is never transmitted anywhere.
Should I reuse the same strong password everywhere?
No — even a strong password becomes risky if reused, since one leaked site can expose every account using that password.
How long should my password be?
Most security guidance now recommends at least 12-16 characters for important accounts, combined with a password manager.
Why avoid predictable substitutions like '@' for 'a'?
Password-cracking tools are specifically trained on these common substitutions, so they add far less real security than most people assume.
Does adding more symbol types help more than adding length?
Length generally contributes more to real cracking-resistance than character variety alone, based on how the underlying combination math works.
Should I still use a strong password if a site has two-factor authentication?
Yes — 2FA adds a second layer of protection, but a strong, unique password remains your first line of defense, especially against database leaks.
Why do password managers make strong random passwords more practical?
Since a password manager remembers the password for you, there's no longer a trade-off between memorability and security — you can use a maximally random, strong password without needing to recall it yourself.
