Password Generator
Generate secure, random passwords directly in your browser.
Why use secure passwords?
Weak passwords are the leading cause of security breaches in personal and business accounts. According to cybersecurity reports, over 80% of data breaches involve compromised or weak passwords. A secure password should have at least 12 characters, combine uppercase, lowercase, numbers, and special symbols, and never be reused across services.
The password generator creates truly random strings using the browser's cryptographically secure random number generator (crypto.getRandomValues), ensuring that each password is unpredictable and unique. Unlike human-created passwords, which follow predictable patterns, randomly generated passwords are virtually impossible to guess through brute force attacks.
Practical use cases
User accounts: Generate unique passwords for each online service. Never reuse passwords: if one service suffers a breach, your other accounts remain secure.
APIs and tokens: Generate API keys, webhook secrets, and secure access tokens for your applications and services.
Databases: Create robust passwords for database users, SSH connections, and certificates.
Security tips
- Use a password manager (Bitwarden, 1Password, KeePass) to store your generated passwords
- Enable two-factor authentication (2FA) whenever possible
- Never share passwords via email or unencrypted messaging
- Change passwords immediately if you suspect they have been compromised
Frequently asked questions
How long does it take to crack a password?
An 8-character password with only lowercase letters can be cracked in less than 1 hour. A 12-character password with all character types (uppercase, lowercase, numbers, symbols) would take billions of years with current technology. Each additional character exponentially multiplies the difficulty.
Are browser-generated passwords secure?
Yes. This tool uses crypto.getRandomValues(), a cryptographically secure browser API that generates high-quality random numbers. All processing happens locally on your device; no passwords are sent to any server.
Is a passphrase better than a password?
Passphrases (like "horse-battery-staple-correct") are easier to remember and can be just as secure if they have enough length. For services you use frequently, a passphrase of 4+ random words is an excellent choice.
Should I change my passwords regularly?
Current NIST guidelines recommend not changing passwords periodically unless there is evidence of compromise. Forced changes lead users to create weaker passwords. Prioritize unique, strong passwords from the start.
