Hey there, fellow tech enthusiasts! Ever found yourself tangled up in the web of user management, SMTP settings, and two-factor authentication? Yeah, it can feel like a real mess. But what if I told you there’s a secret weapon to make this process as smooth as butter? That’s right, we’re diving into the world of environment variables to configure all these settings in n8n. Ready to simplify your life? Let’s get started!
What Are Environment Variables and Why Should You Care?
Environment variables are like the unsung heroes of your system setup. They’re the behind-the-scenes magic that lets you tweak your software without digging into the code. In n8n, these variables are your go-to for setting up user management, SMTP settings, and two-factor authentication. Wondering how this works? Stick with me, and you’ll see how these little tweaks can make a big difference.
Configuring User Management with Environment Variables
Let’s start with user management. This is crucial for any system where multiple users are involved. In n8n, you can use environment variables to fine-tune how your users interact with your system. Here’s how you do it:
- N8N_USER_MANAGEMENT_JWT_SECRET: This variable lets you set a specific JWT secret. If you don’t set it, n8n will generate one for you. But if you want control, this is your ticket.
- N8N_USER_MANAGEMENT_JWT_DURATION_HOURS: Set the expiration duration for JWTs in hours. It defaults to 168 hours, but you can adjust it to fit your needs.
- N8N_USER_MANAGEMENT_JWT_REFRESH_TIMEOUT_HOURS: This sets the refresh timeout for JWTs, defaulting to 25% of the duration. It’s all about keeping things secure and user-friendly.
By using these variables, you’re not just setting up user management; you’re crafting an experience that’s both secure and seamless.
Setting Up SMTP with Environment Variables
Now, let’s talk about SMTP settings. If you’ve ever struggled with email configurations, you know how frustrating it can be. But with environment variables, it’s a breeze. Here’s what you need to know:
- N8N_EMAIL_MODE: This enables emails with a default setting of “smtp”. Simple, right?
- N8N_SMTP_HOST: Specify your SMTP server name here.
- N8N_SMTP_PORT: This is where you set your SMTP server port.
- N8N_SMTP_USER: Your SMTP username goes here.
- N8N_SMTP_PASS: And here’s where you enter your SMTP password.
- N8N_SMTP_OAUTH_SERVICE_CLIENT: Used for 2LO with a service account, requiring a client ID.
- N8N_SMTP_OAUTH_PRIVATE_KEY: Also for 2LO, this one needs a private key.
- N8N_SMTP_SENDER: Specify the sender email address, with an optional name.
- N8N_SMTP_SSL: Determines whether to use SSL for SMTP, defaulting to true.
- N8N_SMTP_STARTTLS: Determines whether to use STARTTLS for SMTP, also defaulting to true.
See? With these variables, you can configure your SMTP settings without breaking a sweat. It’s all about making your life easier.
Two-Factor Authentication: Adding an Extra Layer of Security
Security is non-negotiable, and that’s where two-factor authentication comes in. In n8n, you can enable or disable it using environment variables. Here’s how:
- N8N_MFA_ENABLED: This variable enables or disables two-factor authentication, defaulting to true. But here’s the kicker: n8n will ignore this if existing users already have 2FA enabled.
By setting this up, you’re not just protecting your system; you’re giving your users peace of mind.
Customizing Email Templates
Want to make your emails look slick and professional? Environment variables have got you covered. You can specify the full path to HTML email templates for various purposes:
- N8N_UM_EMAIL_TEMPLATES_INVITE: For invite emails.
- N8N_UM_EMAIL_TEMPLATES_PWRESET: For password reset emails.
- N8N_UM_EMAIL_TEMPLATES_WORKFLOW_SHARED: For workflow sharing notifications.
- N8N_UM_EMAIL_TEMPLATES_CREDENTIALS_SHARED: For credential sharing notifications.
Customizing these templates can make a big difference in user experience. It’s the little details that count, right?
File-Based Settings: A Game Changer
Here’s a cool trick: you can configure environment variables using file-based settings. Just add “_FILE” to the variable name, and you’re good to go. This is perfect for sensitive data like passwords or API keys. It’s all about keeping things secure and organized.
So, there you have it. Environment variables are your secret weapon for configuring user management, SMTP settings, and two-factor authentication in n8n. They’re easy to use, flexible, and can save you a ton of headaches. Give them a try and see the difference for yourself!
