Terraform Cloud


Multi-factor authentication (MFA) is an extra layer of security used when logging into websites or apps to authenticate users through more than one required security and validation procedure that only they know or have access to. Security Assertion Markup Language (SAML) is a protocol for authenticating to web applications. SAML allows federated apps and organizations to communicate and trust one another’s users.

Acceptto™, as a SAML provider, improves the user login experience for Terraform Cloud users with its convenient SSO-MFA solution.


  1. An Acceptto account with a configured Identity Provider and LDAP Agent (See this page for instructions).

  2. A Terraform Cloud user account with administrative access.

  3. A user with administrative privileges for the Acceptto Cloud dashboard.
