CLI Authentication

TACOS (TF Automation and Collaboration Software) are platforms that perform as part of their offering OpenTofu runs to provision infrastructure, offering a collaboration-focused environment that makes it easier for teams to use OpenTofu together.

OpenTofu CLI integrates with TACOS in several ways — it can be a front-end for CLI-driven runs, and can also use some TACOS as a state backend, a private module registry, or a private provider registry. All of these integrations require you to authenticate OpenTofu CLI with your TACOS account.

The best way to handle CLI authentication is with the login and logout commands, which help automate the process of getting an API token for your TACOS user account.
