Password Generator
Generate cryptographically secure passwords, memorable passphrases, and PIN codes with advanced strength analysis.
- •Excellent settings. This password will be very secure.
- •Never reuse passwords across different accounts
- •Consider using a password manager for storage

Password security is your first line of defense against hackers and data breaches. Weak or reused passwords are responsible for over 80% of security breaches. Our password generator uses cryptographically secure random number generation to create passwords that would take millions of years to crack. All generation happens locally in your browser, so your passwords never touch our servers or any network connection.
How to Use This Tool
Choose Generation Mode
Select between Random (maximum security), Passphrase (memorable but secure), or PIN (numeric codes). Each mode is optimized for different use cases.
Customize Your Settings
Adjust password length, character types (uppercase, lowercase, numbers, symbols), and exclude ambiguous characters. Longer passwords with more character types are stronger.
Generate and Review
Click generate to create your password. Review the entropy score and time-to-crack estimate to ensure it meets your security needs.
Copy and Store Securely
Copy your password to clipboard and store it in a password manager. Never write passwords down or store them in plain text files.
Why Use This Tool?
- Cryptographically secure random generation
- Real-time entropy and strength analysis
- Time-to-crack estimates based on current computing power
- Multiple generation modes for different needs
- 100% client-side for maximum privacy
- No data ever sent to servers
- Export multiple passwords to CSV or TXT
- Session history for easy reference
Common Use Cases
High-Security Accounts
Banking, email, and cloud storage accounts need the strongest passwords possible. Use 16+ character random passwords with all character types.
Memorable Master Passwords
For your password manager master password, use a passphrase of 4-6 random words. It's both secure and memorable enough to type regularly.
Application Passwords
When services require app-specific passwords for third-party integrations, generate unique random passwords for each connection.
PIN Codes and Numeric Passwords
For devices, locks, or services requiring numeric-only passwords, use the PIN mode to generate truly random number sequences.
Best Practices
Use a unique password for every account
Never reuse passwords across different services. If one site is breached, attackers will try your credentials on other popular sites.
Aim for 80+ bits of entropy
Passwords with 80+ bits of entropy would take billions of years to crack with current technology. Our tool shows entropy in real-time.
Use a password manager
Store generated passwords in a reputable password manager like 1Password, Bitwarden, or KeePass. This lets you use strong unique passwords without memorizing them.
Enable two-factor authentication
Even the strongest password can be compromised through phishing. Enable 2FA on all accounts that support it for an additional security layer.
Avoid predictable patterns
Don't modify passwords by just adding numbers or symbols at the end. Hackers know these patterns. Always generate completely new random passwords.
