What is Password Generator?
Weak passwords are the leading cause of account breaches worldwide. "123456", "password", and pet names are cracked in seconds by automated tools. A strong password generator creates truly random combinations that are virtually impossible to guess or brute-force. Our free Password Generator uses your browser's Web Crypto API (crypto.getRandomValues) — the same technology banks use — to create cryptographically secure passwords. Customize length from 8 to 64 characters and choose which character sets to include: lowercase, uppercase, numbers, and special symbols. Whether you need a password for your email, banking app, WiFi network, API key, or enterprise system, this tool generates passwords that meet modern security standards. Passwords are created locally in your browser and never sent to any server, stored in any database, or visible to us.

Why is Password Generator Safe?
Password generation uses crypto.getRandomValues() entirely in your browser. We have no ability to see, log, or store generated passwords. This is safer than server-side generators where passwords traverse the network.

Frequently Asked Questions
How long should a password be?
Minimum 12 characters for general accounts, 16+ for important accounts (email, banking). Longer passwords exponentially increase cracking time.
Are generated passwords stored anywhere?
No. Generation happens locally in your browser. We cannot see or store your passwords.
What makes a password strong?
Length (12+ chars), randomness, and character variety (upper, lower, numbers, symbols). Our generator creates passwords meeting all criteria.
Should I use the same password everywhere?
Never. Use a unique password for every account. A password manager helps you store them securely.
Is this better than choosing my own password?
Yes. Humans create predictable patterns. Cryptographic randomness is vastly more secure than memorable phrases.
Can I generate passwords on mobile?
Yes. The tool works on all modern smartphones and tablets.
How strong are the generated passwords?
All passwords use cryptographically secure random number generation. A 16-character password with all character types would take billions of years to crack with current technology.
Do you store the passwords anywhere?
No. All generation happens locally in your browser. Passwords never leave your device.
