How to Set Environment Variables in Replit

‍

This tutorial shows how to store sensitive values like API keys and bot tokens securely in Replit using the Secrets tab.

Note: You need a Replit account and an existing project. Sign up at replit.com if you don't have one yet. Once set, your secret values are hidden from anyone viewing your project - even if it's public. To learn how to access these values inside your code, see How to Use Environment Variables in Replit.

1. Sign in at replit.com and open your project from the dashboard.
2. In your workspace, click New Tab and search for Secrets in the left sidebar (the lock icon).
3. In the Key field, enter a name for your variable - for example, [Name]_TOKEN.
4. In the Value field, paste your secret value - for example, your Telegram or Discord bot token.
5. Click Add/Update new secret to save. Your variable is now available to your project as an environment variable.
