Frequently Asked Questions
Is it safe to type my passwords and API keys into this tool?
Yes. The .env Generator runs 100% in your web browser. No data, API keys, or passwords are ever sent to a server or saved anywhere. It is completely private.
How does the secret generator work?
When you click the "Generate" button next to a secret field, the tool uses your browser's native cryptographic API (`window.crypto`) to generate a highly secure, random 32-character string perfect for JWTs or session encryption.
What is a .env.example file?
A `.env.example` file contains all the variable names your application needs, but with the sensitive values (like passwords and API keys) removed. You can safely commit this file to your git repository so other developers know what variables they need to configure.
