Generate strong, secure random passwords instantly!
A password generator is an essential security tool that creates passwords safe from hacking or brute-force attacks through combinations of uppercase, lowercase, numbers, and special characters.
Uses the browser's Web Crypto API to generate cryptographically secure random values, providing high-quality passwords that are impossible to predict.
Useful for all users managing multiple online accounts to strengthen security with different strong passwords each time.
- 1
Set length
Set password length (4–64 chars). 12–16 is the security/convenience balance point.
- 2
Choose character types
Check uppercase, lowercase, numbers, and symbols. Enable all for maximum strength.
- 3
Click generate
Press generate to display a random password instantly.
- 4
Copy and save
Copy to clipboard, then save to a password manager immediately. Refreshing the page clears it.
Example 1 — General account
Length 16, all types → e.g., 'k9#Lm2@xPq$7nR!w' with 3 uppercase, 6 lowercase, 3 digits, 4 symbols — highly resistant to brute force.
Example 2 — Wi-Fi (no symbols)
Length 12, uppercase+lowercase+digits only → e.g., 'Ht7kM2pLx9Nq'. Symbols excluded for device compatibility.
* Examples are illustrative; actual results differ each time.
Randomly selects characters from the user-chosen character set for the specified length.
Password Security Tips
QIs a longer password always more secure?
Yes. Brute-force resistance grows exponentially with length. At 36 charset, 8 chars = 2.8 trillion combos; 12 chars = 4.7 quintillion. 12–16 characters is the practical sweet spot.
QShould I mix character types?
Including lowercase, uppercase, digits, and symbols expands the character pool (94 chars with all enabled). Check service-specific restrictions first, as some reject certain symbols.
QWhere should I store the generated password?
This tool generates passwords entirely in-browser and stores nothing. Use a dedicated password manager (LastPass, Bitwarden, 1Password). Never store passwords in plain text files.
QCan I recover a previously generated password?
No. Passwords are generated client-side with Math.random() and are not persisted. Save them immediately to a password manager or secure vault.
QIs Math.random() secure enough?
Math.random() is not cryptographically secure, but is adequate for quick password generation. For absolute security (encryption keys), use crypto.getRandomValues() via the Web Crypto API.
