Password Generator
Generate strong, random passwords instantly. Customize length and complexity.
aKS;=_7Z6ESN0H3lHow to create a strong password
- Use at least 16 characters
- Mix uppercase, lowercase, numbers, and symbols
- Avoid dictionary words or personal information
- Use a unique password for every account
- Use a password generator instead of creating one manually
Why use a password generator?
Humans are bad at creating random passwords. We tend to use predictable patterns, dictionary words, and personal details that attackers can guess. A password generator uses cryptographic randomness to create truly unpredictable passwords that are virtually impossible to crack by brute force.
This tool uses your browser's built-in crypto.getRandomValues() API for cryptographically secure random number generation. Your password is generated entirely on your device — it is never sent to any server.
How long should a password be?
| Password Length | Security Level | Use Case |
|---|---|---|
| 8 characters | Minimum | Low-value accounts |
| 12 characters | Good | General accounts |
| 16 characters | Strong | Email, banking, cloud |
| 20+ characters | Very strong | Master passwords, encryption keys |
Frequently Asked Questions
Is this password generator safe?
Yes. This tool runs entirely in your browser. Your generated password never leaves your device — no network requests are made. It uses crypto.getRandomValues(), the same cryptographic API used by password managers.
How long would it take to crack a 16-character password?
A 16-character password using uppercase, lowercase, numbers, and symbols has about 95^16 possible combinations. At 100 billion guesses per second, it would take over 3 billion years to brute-force — making it effectively uncrackable.
Should I use a different password for every account?
Absolutely. If you reuse passwords and one service is breached, attackers will try that password on your other accounts (credential stuffing). Use a unique password for each account and store them in a password manager.
