Authentication
Terraform Enterprise requires a username and password to sign up and login. However, there are several ways to authenticate with your account.
Authentication Tokens
Authentication tokens are keys used to access your account via tools or over the various APIs used in Terraform Enterprise.
You can create new tokens in the token section of your account settings. It's important to keep tokens secure, as they are essentially a password and can be used to access your account or resources. Additionally, token authentication bypasses two factor authentication.
Authenticating Tools
All HashiCorp tools look for the ATLAS_TOKEN environment variable:
$ export ATLAS_TOKEN=TOKEN
This will automatically authenticate all requests against this token. This is the recommended way to authenticate with our various tools. Care should be given to how this token is stored, as it is as good as a password.
Two Factor Authentication
You can optionally enable Two Factor authentication, requiring an SMS or TOTP one-time code every time you log in, after entering your username and password.
You can enable Two Factor authentication in the security section of your account settings.
Be sure to save the generated recovery codes. Each backup code can be used once to sign in if you do not have access to your two-factor authentication device.
Sudo Mode
When accessing certain admin-level pages (adjusting your user profile, for example), you may notice that you're prompted for your password, even though you're already logged in. This is by design, and aims to help guard protect you if your screen is unlocked and unattended.
Session Management
You can see a list of your active sessions on your security settings page. From here, you can revoke sessions, in case you have lost access to a machine from which you were accessing.
