Free Strong Password Generator
A strong password generator creates long, random passwords that are virtually impossible to guess or crack. Using a unique random password for every account is one of the most effective things you can do to protect your online security.
Our generator runs entirely in your browser using JavaScript's cryptographically secure crypto.getRandomValues() API. Passwords are generated locally — never sent to any server, never logged, never stored.
🔐 Cryptographically Secure
Uses crypto.getRandomValues() — not predictable Math.random().
🎛 Fully Customisable
Set length, toggle uppercase, lowercase, numbers and symbols.
🚫 Never Stored
Generated locally — nothing ever leaves your device.
📋 One-Click Copy
Click any password to copy it to clipboard instantly.
How to Generate a Strong Password
1
Set your length
Use the slider to set password length. Minimum 16 characters recommended. For banking or email, use 20+ characters.
2
Choose character types
Enable uppercase (A–Z), lowercase (a–z), numbers (0–9) and symbols (!@#$%). Using all four types dramatically increases security.
3
Generate and copy
Click Generate to create a new password. Click the copy button to copy it to clipboard instantly.
4
Save in a password manager
Store in Bitwarden (free), 1Password or LastPass so you never need to remember it.
What Makes a Password Strong?
- Length: Every extra character multiplies possible combinations exponentially. 16 characters is far harder to crack than 8.
- Randomness: Avoid words, names, dates and keyboard patterns. True random generation is essential.
- Character variety: Mixing all four character types creates a much larger possible character set.
- Uniqueness: A different password for every account — if one site is breached, others stay safe.
Frequently Asked Questions
Is it safe to use an online password generator?
Yes — as long as it runs locally without sending data to a server. This tool uses JavaScript's built-in crypto.getRandomValues() API. You can verify this by turning off your internet connection and refreshing — the generator still works, because no server is involved at all.
How long should my password be?
Security experts recommend at least 12–16 characters for everyday accounts, and 20+ for high-value accounts like email and banking. A 16-character random password with mixed characters would take billions of years to brute-force — effectively uncrackable.
Should I use symbols in my password?
Yes, if the website allows it. Symbols significantly increase the character set — moving from 62 to ~95 characters. A 16-character password using letters, numbers and symbols is billions of times harder to crack than letters and numbers alone.
Do I need a password manager?
If you use strong unique passwords for every account (which you should), yes. You can't memorise 50 different 20-character random strings. Bitwarden is free, open-source and works across all devices. It's one of the best security tools available.
What is the difference between a password and a passphrase?
A password is a random string of characters. A passphrase is a sequence of random words — like "correct-horse-battery-staple". Passphrases are easier to remember and equally secure if they are 4+ random words. Good for accounts you type frequently without a password manager.
