Learn how to hide an API key in GitHub with this easy step-by-step tutorial. If your project uses API keys, tokens, passwords, or other sensitive credentials, it’s important to keep them out of your GitHub repository, especially when the repository is public.

In this tutorial, I’ll show you how to safely manage an API key in a GitHub project without directly exposing it in your source code. You’ll learn how to move sensitive values into environment variables or a separate environment configuration file and keep those files out of Git version control.

We’ll go through the process step by step, including creating an environment file, storing your API key securely, accessing the value from your application, and adding the appropriate file to .gitignore so it isn’t accidentally committed to GitHub.

Keeping API keys out of your source code is an important security practice. If a secret is accidentally pushed to a public repository, simply deleting the file from the latest version may not be enough because the secret can remain in Git history.

We’ll also discuss what to do if an API key has already been exposed on GitHub. In that situation, you should revoke or rotate the compromised key through the service that issued it rather than relying only on deleting the key from your repository.

For projects deployed through platforms such as Vercel, Netlify, or other hosting services, you can also use their environment-variable settings to store secrets separately from your source code.

GitHub also provides security features such as secret scanning to help detect certain exposed credentials, but prevention is still the best approach.

Whether you’re building a website, application, automation tool, or API-based project, this tutorial will help you understand how to protect sensitive credentials while using GitHub.

By the end of this video, you’ll know how to hide an API key in GitHub and how to prevent sensitive credentials from being accidentally uploaded to your repository.
