When to Use This Tool
- You need to create strong passwords for online accounts, email, or services
- You want to generate secure passwords that meet specific requirements (length, character types)
- You're setting up new accounts and need unique, random passwords
- You want to update existing passwords with stronger, more secure alternatives
- You need passwords for applications, databases, or API keys
- You're creating passwords for team accounts or shared services
- You want cryptographically secure random passwords (uses Web Crypto API)
- You need to generate passwords offline without browser access (use command-line tools)
- You require passwords with specific patterns or memorable phrases (this tool generates random passwords)
- You need to generate passwords for systems with very specific character restrictions
- You want to generate passwords based on personal information (random passwords are more secure)
- You need to generate passwords in bulk for thousands of accounts (use specialized tools)
What is a Password Generator?
A password generator creates cryptographically secure, random passwords using configurable character sets — uppercase, lowercase, numbers, and special characters. Our generator runs entirely in your browser using the Web Crypto API — generated passwords are never transmitted or stored anywhere.
Strong, unique passwords are the foundation of digital security. Data breaches expose millions of weak and reused passwords every year. Using a random password generator ensures your passwords have maximum entropy and cannot be guessed through dictionary attacks or common pattern matching.
This tool is essential for anyone creating accounts on new services, IT administrators provisioning user accounts, security-conscious professionals maintaining unique passwords for each service, developers generating API keys and secrets, and system administrators creating service account credentials.
Compared to browser built-in password generators (limited customization), password manager generators (require installing the manager first), or online generators that could potentially log generated passwords, PureXio generates passwords using the browser's cryptographically secure random number generator (crypto.getRandomValues) with zero network activity. Your generated passwords exist only in your browser memory.
The tool offers configurable password length (8–128 characters), toggleable character sets, exclusion of ambiguous characters (0/O, 1/l/I), password strength indicator, generation of multiple passwords at once, and a one-click copy button. Each generated password includes an entropy calculation showing its strength.
Best for: generating cryptographically secure passwords. Configurable length, character sets, strength indicator. Uses Web Crypto API. Zero data transmission.
How to Generate Passwords
Set password length (4-128 characters). Longer passwords are more secure. Enable/disable character types: uppercase letters, lowercase letters, numbers, and symbols
Click 'Generate Secure Password' to create a random password. Password appears instantly with strength indicator showing security level
Copy password to clipboard. Use for accounts, services, or any password needs. Regenerate to create a new password with same settings
Common Use Cases
Create strong passwords for email accounts, social media, or online services
Generate secure passwords for work accounts or business applications
Create passwords for database access, API keys, or server credentials
Generate passwords for team accounts or shared services
Create passwords for new account registrations
Update existing weak passwords with stronger, randomly generated alternatives
Generate passwords for applications or services that require secure authentication
Features
Limitations & Constraints
Password length limited to 4-128 characters—very long passwords may be impractical
Requires browser with Web Crypto API support (modern browsers only)
Passwords are random—not memorable or easy to type (use password managers to store)
Cannot generate passwords with specific patterns or personal information
Password strength is based on length and character variety—doesn't check against password databases
Troubleshooting
Password generation fails or shows error
Solution: Ensure at least one character type is selected (uppercase, lowercase, numbers, or symbols). Password length must be between 4 and 128 characters. Ensure you're using a modern browser with Web Crypto API support. Try refreshing the page or using a different browser. Prevention: Select at least one character type and use length between 4-128 characters.
Password doesn't meet website requirements
Solution: Some websites have specific password requirements (e.g., must include special characters, no spaces). Adjust character type options to match requirements. If website requires specific characters, you may need to manually edit the generated password. Check website password requirements first, then configure generator accordingly. Prevention: Review website password requirements before generating.
Password is too weak or too strong
Solution: Password strength depends on length and character variety. Increase length for stronger passwords (16+ characters recommended). Enable all character types (uppercase, lowercase, numbers, symbols) for maximum strength. Very short passwords (under 8 characters) are weak. Prevention: Use 16+ characters with all character types for strong passwords.
Need to generate password offline
Solution: Once the page is loaded, password generation works offline using Web Crypto API. However, initial page load requires internet. For completely offline generation, use command-line tools or password manager applications. Prevention: Load the page while online, then use offline for password generation.
Password is hard to remember or type
Solution: Random passwords are intentionally hard to remember—this makes them more secure. Use a password manager to store passwords securely. Don't try to memorize random passwords. For accounts you access frequently, use a password manager with autofill. Prevention: Use password managers—don't try to memorize random passwords.
