Password Security Tips
Use 16+ Characters
Longer passwords are exponentially harder to crack. 16 characters with mixed types takes centuries to brute-force.
Never Reuse Passwords
Each account needs a unique password. If one site gets breached, reused passwords put all your accounts at risk.
Use a Password Manager
Store generated passwords in a manager like Bitwarden (free), 1Password, or LastPass — never in a text file.
Enable 2FA Everywhere
Two-factor authentication adds a second layer of security even if your password is compromised.
Include All Character Types
Mix uppercase, lowercase, numbers, and symbols for the strongest possible passwords against dictionary attacks.
Change Critical Passwords
Update passwords for banking, email, and social accounts every 6–12 months or immediately after any breach.
Why Use This Password Generator?
Cryptographically Secure
Uses the Web Crypto API (crypto.getRandomValues) — the same standard used by banks and security professionals. Far more secure than Math.random().
100% Browser-Based
No server calls. Your passwords are generated and stay on your device — they are never transmitted, logged, or stored anywhere.
Fully Customizable
Control length (4–64 chars), character sets (uppercase, lowercase, numbers, symbols), exclude ambiguous chars, and generate up to 10 passwords at once.

Frequently Asked Questions
Is this password generator secure?
Yes. This tool uses the Web Crypto API (crypto.getRandomValues), which generates true cryptographically secure random numbers. It is far more secure than Math.random() and is the same standard used by security professionals. Importantly, all generation happens in your browser — passwords never leave your device.
How long should my password be?
For most accounts, 16 characters with all character types is the gold standard. For banking and email accounts, use 20+ characters. A 16-character mixed password has over 10^29 combinations — it would take centuries to crack by brute force.
What does 'Exclude Ambiguous Characters' mean?
This removes characters that look similar in certain fonts: I (capital i), l (lowercase L), 1 (one), O (capital o), and 0 (zero). This is useful when you need to read or type the password manually without copying and pasting.
Should I use a password manager?
Yes, absolutely. We recommend Bitwarden (free, open-source), 1Password, or KeePass. Store your generated passwords in a manager so you can use a unique strong password for every account without memorizing them.
Can I trust this tool with my passwords?
Completely. The passwords are generated using JavaScript running locally in your browser. They are never sent to our servers, never logged, and never stored. You can even use this tool offline — disconnect from the internet and the generator still works.
