Authentication with Atlas

Atlas requires a username and password to sign up and login. However, there are several ways to authenticate with your Atlas account.

Authentication Tokens

Authentication tokens are keys used to access your account via tools or over the various APIs used in Atlas.

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 with Atlas 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.

Vagrant Login

Only Vagrant allows for a vagrant login command, but it can be used to login and automatically create an authentication token from Vagrant.

$ vagrant login
# ...
Atlas username:
Atlas password:

You can read more about vagrant login and its options in the Vagrant documentation. You cannot use Vagrant login with Two Factor authentication.

Sudo Mode

When accessing certain admin-level pages on Atlas (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 Atlas.
