Email Verification OTP

What is this?

Email verification is a new and unique feature that we've implemented in the event that someone wants to keep their deployment of Nebula private and secure.

What does it do

When a user tries to access the website, before allowed access they will be asked for a One time password sent to an email set in the deployment configuration. Once verified, they will have 15 day access to the site.

SendGrid Setup Instructions

• Firstly, We need to enable verification within the deployment configuration

  • change "sendgrid_verification":false, to "sendgrid_verification":true, above the SendGrid Section

  • Note: You have to reboot the node app for any changes to take place.

• Now, we need to use an api to send a message

  • Make an account at Sendgrid (https://app.sendgrid.com/)
  • Note: It is likely that other versions of Nebula will use a different package to send emails.

• Verify the email you want to recieve emails from (Create a sender identity)

  • Go to settings -> Sender authentication and click Verify a Single Sender

• Now, We need to get the API key to connect to the API

  • Go to settings -> API Keys -> and make an API key.

• Complete the information in the deployment config deployment.config.json under the sendgrid_options section such as: sendFromEmail, to_email and api_key

Discord Webhook Setup Instructions

• Set discord_verification to true in the deployment configuration.
• Create a channel in a discord server you have admin in.
• Click the Edit Channel button.
• Click Integrations
• Click create web hook and copy the URL.
• Paste it under the webhook_url section in the deployment configuration.

SMTP Setup Instructions

• Set smtp_verification to true.
• Change to_email to the email address you want the codes to be sent to.
• Change `sendFromEmail to the email address that is going to send the codes.
• Get the host and port from your email provider's documentation.
• Fill in your username and password under the user and pass section under auth.

Server configuration

• SSH into the server you'll be using, I'll assume its running Ubuntu 22.04 (though the commands are the same for debian 10+ versions, and Ubuntu versions 20.04+)
• run

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash - \ &&
sudo apt-get install -y nodejs npm
git clone https://github.com/NebulaServices/Nebula.git
cd Nebula
npm i
npm ci
sudo nohup PORT=80 node . &

Make sure your firewall is configured to let through port 80 traffic!
Note: Server will need to run cd Nebula && sudo nohup PORT=80 node . & on reboot
