Security Best Practices

JWT Security Best Practices

Always use strong secret keys, set appropriate expiration times, and validate tokens on the server side. Never store sensitive data in JWT payloads.

Password Security

Use strong, unique passwords with a mix of characters. Consider using our password generator for creating secure passwords.

Data Validation

Always validate and sanitize user input. Use our JSON validator and regex tester to ensure data integrity.

Secure Data Transmission

Use HTTPS and proper encoding (Base64) for data transmission. Our URL encoder helps ensure special characters are properly handled.
