How to Generate a Secure Password
1
Set password length
Drag the slider to choose a length. 16+ characters is recommended for most accounts. 20+ for banking and email.
2
Choose character types
Enable uppercase, lowercase, numbers and symbols for maximum entropy. Check Exclude Ambiguous to avoid confusable characters.
3
Click Generate
Instantly creates cryptographically secure passwords using your browser's crypto.getRandomValues API — never Math.random().
4
Copy and store
Click Copy next to any password. Use ⬇ .txt to save a batch file. Store all passwords in a password manager like Bitwarden.
❓ Frequently Asked Questions
How does the password generator work?+
It uses your browser's built-in cryptographically secure random number generator (crypto.getRandomValues) to pick characters from the character sets you select. This is far more secure than Math.random() and is the same API used by professional security tools.
Is my generated password stored anywhere?+
No. Everything happens entirely in your browser. No password is ever sent to any server. Your generated passwords are 100% private and leave no trace.
What makes a password strong?+
Length is the single biggest factor. A 20-character password with mixed characters is exponentially harder to crack than a 10-character one. We recommend at least 16 characters with uppercase, lowercase, numbers and symbols, giving 80+ bits of entropy.
What is password entropy?+
Entropy measures how unpredictable a password is in bits, calculated as length × log₂(pool size). A 16-character password with all character types has about 100 bits of entropy — effectively uncrackable with current hardware.
Should I use a password manager?+
Yes — always. Use this tool to generate strong passwords, then store them in a password manager like Bitwarden (free, open-source) or 1Password so you never need to remember them. Never reuse passwords across accounts.
