JWT Secret Generator

What is a JWT Secret?

A JWT (JSON Web Token) secret is a private key used to sign and verify tokens in your application. This secret ensures that tokens cannot be tampered with or forged by malicious actors.

Why Use a Strong JWT Secret?

The security of your entire JWT authentication system depends on keeping your secret key secure and making it difficult to guess. A weak or predictable secret could allow attackers to forge valid tokens and gain unauthorized access to your application.

Best Practices for JWT Secrets

• Use long, random secrets - Your JWT secret should be at least 32 characters and contain a mix of letters, numbers, and special characters.
• Keep your secret private - Never expose your JWT secret in client-side code or public repositories.
• Rotate secrets periodically - Change your JWT secret regularly, especially after team member departures or suspected breaches.
• Use environment variables - Store your JWT secret in environment variables rather than hardcoding it in your application.
• Consider using asymmetric keys - For higher security, consider using RS256 (RSA) or ES256 (ECDSA) algorithms with public/private key pairs instead of symmetric secrets.

How Our Generator Works

Our JWT secret generator creates cryptographically secure random strings using your browser's built-in cryptographic functions. The generated secrets never leave your device or get sent to our servers, ensuring complete privacy.
