title: Sharing Terraform tfvars among organization
body: <p>I am new to cloud development and I am trying to learn how variables are shared among organizations.
  Suppose I create a terraform infrastructure and a state file is stored on Remote s3 bucket. Now I give all the variables via terraform.tfvars file and store them on my machine and do not commit that file to the repository.
  Now If another developer wants to change the infrastructure, he has to know the values of tfvars (terraform.tfvars or backend.tfvars) files. How will I share with him securely?</p>
  <p>For example:</p>
  <p>In my terraform.tfvars I have</p>
  <pre><code>region=&quot;us-east-1&quot;
  vpc_cidr=&quot;192.168.0.0/16&quot;
  vpc_name=&quot;my-vpc&quot;
  Rds_password=&quot;password&quot; 
  Rds_username=&quot;username&quot; 
  </code></pre>
  <p>Now when some have to make a change to my infrastructure they need all the above values, So how will I share my terraform.tfvars file? The solution should scale to many developers</p>
