Free Strong Password Generator
Create unbreakable passwords in seconds with our free password generator. Customize length, character types, and complexity to match any website's requirements. Every password is generated using cryptographically secure random methods directly in your browser. Never transmitted, never stored, never logged. Whether you need one strong password or twenty unique ones for different accounts, generate them safely without leaving your device.
How to Generate Strong Passwords
- 1
Set Your Password Length
Use the slider to choose any length between 8 and 64 characters. Longer is always stronger. We recommend at least 16 characters for important accounts.
- 2
Choose Character Types
Select which character types to include: uppercase letters, lowercase letters, numbers, and symbols. Add the "exclude similar characters" option to avoid confusion between O and 0, or l and 1.
- 3
Generate and Copy
Click generate to create your password and watch the strength meter confirm its security. Copy with one click and use it immediately. Generate multiple passwords at once if you need several.
Features That Keep You Secure
Cryptographically Secure
Uses your browser's built-in crypto.getRandomValues(), the same technology that powers banking websites. Every password is truly random, not predictable.
Real-Time Strength Meter
Visual feedback shows password strength as Weak, Fair, Good, or Strong based on length and character diversity, helping you make informed security choices.
Bulk Generation
Need passwords for multiple accounts? Generate up to 20 unique passwords at once and copy them all individually with a single click.
Customizable Complexity
Match any website's password requirements with granular control over length, uppercase, lowercase, numbers, symbols, and similar/ambiguous character exclusion.
Session History
Recently generated passwords are kept in browser memory during your session for quick reference, then erased completely when you close the tab.
Browser-Based Generation
Passwords are generated entirely on your device using the browser's cryptographic API. No server processing, no logs of generated passwords.
Why Our Password Generator Is Safer Than Most
Many online password generators send your settings to a server, which then returns a generated password. This means the server theoretically knows what password it created for you. Our tool uses your browser's native cryptographic functions, so password generation happens entirely on your device. Nothing is transmitted, nothing is logged, and nothing is recoverable. Even we cannot see what passwords you generate. This is the safest possible architecture for a password tool.
When You Need Strong Passwords
Creating New Accounts
Generate unique, uncrackable passwords for every new service you sign up for: email, banking, shopping, social media, work tools.
Updating Compromised Passwords
After a data breach notification, quickly create strong replacement passwords for affected accounts to prevent unauthorized access.
Setting Up Password Managers
Generate the master password for your password manager, plus replacements for every existing weak password stored within.
Configuring WiFi Networks
Create secure WiFi passwords for home routers, guest networks, or office networks that resist brute-force attacks.
Building Application Secrets
Developers can generate API keys, encryption salts, JWT secrets, and database passwords with appropriate length and entropy.
