Secure Password Generator
Weak passwords are one of the easiest ways to lose accounts in a data breach. This Secure Password Generator creates strong random passwords with high entropy, so they’re far harder to guess or brute-force.
Customize length and character sets to match website requirements, and generate passwords locally in your browser.

How it works
The generator creates random strings based on the settings you choose. You can control password strength by adjusting:
- Length: longer passwords are exponentially harder to crack.
- Character sets: uppercase, lowercase, numbers, and symbols.
- Similar characters: optionally exclude confusing characters like
O/0orl/1.
Passwords are generated locally in your browser and are not transmitted or stored on our servers.
Example uses
- Creating a strong password for a new account
- Generating unique passwords for email, banking, and social media
- Rotating passwords during a security checkup
- Setting up credentials for new devices or apps
- Generating multiple passwords for teams or test environments

How long would it take to crack a 12-character random password?
With current technology, a 12-character password using a mix of letters, numbers, and symbols would take a standard computer can take a very long time depending on the attacker’s hardware and method to crack via brute force.
Should I use the same password for different sites?
Absolutely not. If one site is breached, hackers will try that same password on your email, bank, and social media. Always use a unique password for every service.
How can I remember these complex passwords?
We recommend using a reputable Password Manager. You only need to remember one strong “Master Password,” and the manager will store and auto-fill the rest for you.
