<Aside type="tip" title="Experimental">
This flag is gated behind the [`opt-out-auth`](/reference/experiments/active#opt-out-auth) experiment. Enable it with `--experiment=opt-out-auth` (or `TG_EXPERIMENT=opt-out-auth`); otherwise setting `--no-discovery-auth-provider-cmd` returns an error. The flag's behavior may change while the experiment is in progress.
</Aside>

Skip running `--auth-provider-cmd` during the discovery phase.

By default, Terragrunt runs `--auth-provider-cmd` once per parse of a component during the discovery phase so configuration parsing can resolve HCL functions such as `get_aws_account_id` without error. With this flag, those discovery-time invocations are skipped. The auth provider command still executes normally for the units that actually run.

<Aside type="caution">
Units whose discovery-relevant blocks depend on credentials produced by `--auth-provider-cmd` may fail to parse with this flag set.
