Frequently Asked Questions

Everything you need to know about Security Tools

Yes! All our security tools including password generator, email verifier, IP address lookup, and fake data generator are 100% free with no hidden charges, subscriptions, trial periods, or usage limitations. You can use them unlimited times without signing up or creating an account.

Our password generator creates cryptographically secure random passwords using JavaScript's crypto.getRandomValues() API. You can customize length (8-128 characters), include uppercase, lowercase, numbers, and special symbols. Passwords with 16+ characters including all character types are virtually uncrackable. All generation happens locally in your browser - passwords are never sent to servers or stored anywhere.

Our email verifier validates email addresses through multiple checks: syntax validation (RFC 5322 standard), domain DNS validation, MX record verification, and disposable email detection. It checks if the email format is correct, the domain exists, and can receive mail. This helps reduce bounce rates for email campaigns, validate form inputs, and prevent fake email signups.

The IP address info tool provides comprehensive details about any IP address including: geolocation (country, city, region), ISP/organization, timezone, coordinates (latitude/longitude), connection type, and domain information. It works for both IPv4 and IPv6 addresses. Useful for security monitoring, fraud detection, content localization, and network diagnostics. You can check your own IP or any public IP address.

Yes! Privacy is our top priority. The password generator operates entirely client-side in your browser - passwords are generated locally and never transmitted anywhere. Email verification uses secure API calls without storing data. The fake data generator creates random information client-side. We never log, store, or share your inputs. For maximum security, tools process data locally whenever possible.

The fake data generator creates realistic but completely fictional test data including names, addresses, emails, phone numbers, and more. It's perfect for: populating development databases, testing application forms, QA and software testing, creating demo data, API testing, and protecting real user privacy during development. All generated data is random and not associated with real people or businesses.

No account or signup needed! All security tools (password generator, email verifier, IP lookup, fake data generator) work instantly without registration. Simply open the tool and start using it. No email required, no personal information needed, and no tracking. We believe in frictionless access to security utilities - just open and use.

Yes! All security tools are fully responsive and optimized for mobile devices, tablets, and desktops. Whether you're using iPhone, Android, iPad, or any smartphone, the tools work perfectly with touch interfaces. Generate passwords on the go, verify emails from your phone, or check IP addresses from any device. The responsive design ensures great experience on any screen size.

Password Security Best Practices

Strong passwords should be at least 16 characters long, include uppercase and lowercase letters, numbers, and special symbols, and be unique for every account. Never reuse passwords across multiple services. Use our password generator to create cryptographically secure random passwords. Consider using a password manager to store passwords securely. Enable two-factor authentication (2FA) wherever possible. Change passwords regularly, especially for critical accounts like email, banking, and social media. Avoid dictionary words, personal information, and common patterns. Don't share passwords via unsecured channels like email or SMS.

Email Validation Importance

Email validation is crucial for maintaining sender reputation, reducing bounce rates, preventing fake signups, improving email deliverability, protecting against spam traps, validating user identities, and ensuring communication reaches recipients. Our email verifier checks syntax correctness, domain validity, MX records, and identifies disposable/temporary email addresses. Businesses using email validation see up to 98% reduction in bounce rates, improved sender scores, better email engagement, and reduced costs from invalid email addresses.
