Random Password Generator
Generate a strong, random password with a custom length and character set.
Passwords are generated locally in your browser and are never sent anywhere.
About this tool
This tool generates cryptographically random passwords directly in your browser, using the Web Crypto API's secure random number generator rather than a predictable pseudo-random function. No password is ever transmitted to or stored on a server.
You can control the length (from 4 to 64 characters) and which character sets are included — uppercase letters, lowercase letters, numbers and symbols — to match a specific site's password requirements or your own security preferences.
A strong, unique, randomly generated password for every account is one of the single most effective defenses against credential stuffing and brute-force attacks — the two most common ways stolen passwords lead to compromised accounts.

Frequently asked questions
- Is it safe to generate passwords online?
- This generator runs entirely in your browser using the Web Crypto API's cryptographically secure random number generator. Your password is generated locally and is never transmitted to any server.
- How long should a password be?
- Security experts generally recommend at least 12-16 characters for everyday accounts, mixing uppercase, lowercase, numbers and symbols. Longer passwords are exponentially harder to crack: each extra character multiplies the number of possible combinations.
- Why use a random password instead of one I can remember?
- Passwords based on words, names or patterns are far easier for attackers to guess or crack using dictionary and pattern-based attacks. A truly random password of sufficient length is dramatically more resistant to brute-force attacks — pair it with a password manager so you don't have to memorize it.
- Should I use a different password for every site?
- Yes. Reusing passwords means that if one site is breached, attackers can try the same credentials on your other accounts (a technique called credential stuffing). Generating a unique random password for each account, stored in a password manager, avoids this risk entirely.
- What makes a password hard to crack?
- Length matters more than complexity tricks like swapping letters for symbols. A longer password drawn from a wide character set (uppercase, lowercase, numbers, symbols) has far more possible combinations for an attacker to try, which is why this generator lets you control both.
