## ❓ I don't already have an SMTP capable email

If your provider doesn't support **standard SMTP**, the easiest solution is to create a **free Gmail account** dedicated to your server. 

Gmail allows you to generate an **App Password** which works perfectly for automated alerts.

1. Navigate to the [Google account creation page](https://accounts.google.com/signup). Follow the prompts to create your account. Feel free **not to provide** real information about yourself. Giving your phone number and home address is **not needed**.

2. Once your account is **created** navigate to the [Google account settings](https://myaccount.google.com).

3. In the security page, enable the **two factor authentication (2FA)**. The best way to enable 2FA without providing too much information is using **TOTP codes** (under Authenticator label). You can use the open-source [Ente Auth](https://ente.io/auth/) app to get your **TOTP codes**.

4. Finally, once **2FA** is enabled, you can generate an **app password**. Navigate to the [app passwords page](https://myaccount.google.com/apppasswords). Generate an app password and call it "numbus-server" to **remember** what it is used for.
