Customize length and character types to generate strong random passwords
With growing cybersecurity threats, weak passwords are a leading cause of account compromise. Verizon's Data Breach Investigations Report finds that the vast majority of breaches involve weak, stolen, or compromised credentials. A password generator is a dedicated security tool for creating strong, random passwords that protect your online accounts.
Our generator uses a cryptographically secure random number algorithm, so every password is highly random and unpredictable. You can customize the length (8-64 characters) and the character sets (uppercase, lowercase, numbers, symbols) and exclude similar-looking characters for passwords that are both secure and easy to use.
It also offers one-click copy so you can paste the generated password wherever you need it. The entire process runs locally in your browser — nothing is uploaded to a server — keeping your passwords safe. Pair strong passwords with a password manager to significantly improve the security of your digital assets.
Every password is created entirely on your device, right in your browser. Here's what that means in practice:
Cryptographically secure randomness. We use the browser's Web Crypto API (crypto.getRandomValues) — the same hardened random source used by modern operating systems and password managers — never the predictable Math.random().
No modulo bias. Each character is drawn with rejection sampling, so every symbol in your chosen set has a mathematically equal chance of appearing.
Guaranteed variety. Every password includes at least one character from each set you select, then is shuffled so the pattern can't be predicted.
100% local — nothing leaves your device. No server, no uploads, no logs. Close the tab and every generated password is gone for good.
Customize password length from 8 to 64 characters to meet the security requirements of different sites and services.
Combine uppercase, lowercase, numbers, and symbols in any way to generate strong passwords.
Exclude confusing characters (i, l, 1, L, o, 0, O, etc.) to create passwords that are secure yet easy to read.
Copy the generated password to the clipboard with one click for quick use.
Passwords are generated locally and never uploaded to a server, keeping them secure and protecting your privacy.
Strong passwords are essential for protecting your online security. Here's why:
Prevent brute-force attacks: Strong passwords significantly reduce the risk of brute-force attacks. A 12-character strong password (with mixed case, numbers, and symbols) can take hundreds or even thousands of years to crack, while a simple 8-character password may fall in minutes. NIST's digital identity guidelines recommend prioritizing length over complexity.
Protect personal and sensitive data: Strong passwords are your first line of defense for personal information, financial data, and online identity. Breach statistics show most security incidents involve weak or reused passwords.
Protect business data and reputation: For businesses, strong password policies help prevent data leaks, protect intellectual property and trade secrets, and avoid the financial losses and reputational damage of security incidents.
Meet security compliance requirements: Many industry standards and regulations (such as GDPR, HIPAA, PCI DSS) require strong passwords and periodic rotation as a baseline, helping businesses and individuals avoid compliance risk.
Length plus variety. A strong password is long (12+ characters) and mixes uppercase, lowercase, numbers, and symbols, which makes it far harder to guess or brute-force.
Yes. Passwords are generated in your browser from a cryptographically secure random source, never from a predictable formula or a server.
Aim for at least 12–16 characters. Longer is stronger, especially for important accounts like email, banking, and work logins.
Yes. Passwords are generated 100% in your browser — they are never uploaded, stored, or sent anywhere.
Use a passphrase: string together four or more random words (for example, "coral-harbor-lemon-42"). It's long, hard to crack, and easier to remember than random characters.
Use a breach-checking service like Have I Been Pwned, which compares your password against known data breaches without revealing it.
Both. Use a generator to create a unique, random password for each account, then store it in a password manager so you only have to remember one master password.
No. Reusing a password means one breach exposes every account that shares it. Generate a unique password for each site.
