Online Password Generator — Secure & Free
Weak passwords are the number one cause of security breaches. "password123," your dog's name, your birthday — attackers crack these in seconds. The solution is simple: use long, random passwords that are impossible to guess. The problem? Humans are terrible at creating truly random strings. That's what password generators are for.
Why You Need a Password Generator
Here's the uncomfortable truth about password security:
- A 6-character password can be cracked in under a second by modern hardware.
- An 8-character password with mixed characters takes about 8 hours to crack.
- A 12-character random password takes centuries to crack.
- A 16-character random password is effectively uncrackable with current technology.
The key word is "random." Humans think they're being random when they choose passwords, but we follow predictable patterns — capitalizing the first letter, adding a number at the end, substituting @ for a. Attackers know these patterns and exploit them. A truly random password generator eliminates human bias entirely.
How to Generate a Strong Password
- Open the password generator tool.
- Set your preferences — length, uppercase, lowercase, numbers, symbols.
- Click generate and copy your new password.
The password is generated using your browser's crypto.getRandomValues() API — a cryptographically secure random number generator. Your password is created on your device and never transmitted anywhere.

Generate Password →What Makes a Password Strong?
- Length — This is the single most important factor. Every additional character exponentially increases the number of possible combinations. Aim for 16+ characters.
- Randomness — No dictionary words, no patterns, no personal information. True randomness from a cryptographic source.
- Character variety — Use uppercase, lowercase, numbers, and symbols. This increases the character set from 26 (lowercase only) to 95+ possibilities per position.
- Uniqueness — Every account should have its own password. Reusing passwords means one breach compromises all your accounts.
Password Generator vs Password Manager
A password generator creates individual passwords. A password manager stores and auto-fills them. You need both:
- Password generator — Creates strong, random passwords on demand. Use our free generator when you need a new password.
- Password manager — Stores all your passwords securely. Popular options include Bitwarden (free, open-source), 1Password, and KeePass.
The workflow: generate a strong random password, save it in your password manager, and never think about it again. You only need to remember one master password — the one for your password manager.
How Long Should Your Password Be?
Our recommendations based on current security standards:
- 12 characters — Minimum for any account. Adequate for low-risk accounts.
- 16 characters — Recommended for most accounts. Excellent security.
- 20+ characters — Use for critical accounts: email, banking, password manager master password.
- 32+ characters — For API keys, encryption keys, and machine credentials.
Passphrase Alternative
If you need a password you can actually type (like a master password), consider a passphrase — a sequence of random words:
correct-horse-battery-staple-mountain
A 5-word passphrase is both strong and memorable. The key is that the words must be chosen randomly, not selected by you. Human-chosen "random" words follow predictable patterns.
Common Password Mistakes
- Reusing passwords — If one site gets breached, attackers try that password on every other site you use.
- Minor variations — Using "MyPassword1" on one site and "MyPassword2" on another provides almost no additional security.
- Personal information — Names, birthdays, addresses, and pet names are easily researched or guessed.
- Keyboard patterns — "qwerty," "123456," "zxcvbn" — these are the first patterns attackers try.
- Dictionary words — Even obscure words are in attackers' dictionaries. All of them.
- Short passwords with complexity — "P@ss1!" looks complex but is only 6 characters. Length beats complexity every time.
