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.
