AWS introduced account access manager, an IAM Identity Center capability that assigns existing IAM roles (instead of permission sets) to Identity Center users/groups, with a simplified aws login CLI flow and its own account-access API namespace. Three of our pages made claims this makes stale.

Changes

  • content/docs/startups.md — "Why not IAM Identity Center?" table: permission sets are no longer the only assignment model, and aws sso login is no longer the only CLI flow. Both rows updated; the overall argument (Organizations + Identity Center instance + sync still required, browser SSO, AWS-only) is unchanged.
  • content/docs/aws-multi-account.md — added a callout in the Identity Center section: Vouch's trusted-token-issuer discovery uses the SSO portal APIs (ListAccounts/ListAccountRoles/GetRoleCredentials), so vouch setup aws --discover surfaces permission-set assignments only — account access manager assignments live in the separate account-access namespace and are not discovered. Readers are pointed at role chaining or direct OIDC federation for those roles (they are ordinary IAM roles). Verified against the CLI source (crates/vouch-cli/src/integrations/aws/sso_portal.rs calls only the SSO portal APIs). Also a one-line pointer in the page intro.
  • content/compare/_index.md — "Choose IAM Identity Center when" wording generalized from "complex permission sets" to permission sets or centrally assigned IAM roles.

Not in scope

CLI support for discovering account access manager entitlements (via account-access:ListEntitlements) and vending credentials for entitled roles through role chaining is now tracked in vouch-sh/vouch#901. The docs note in this PR is written as a current limitation and should be revised when that lands.

AWS account access manager lets Identity Center assign existing IAM
roles (no permission sets) and adds the simplified aws login CLI flow.
Update the startups comparison table so both claims stay accurate.

Roles assigned through Identity Center's account access manager live in

(SSO portal APIs) surfaces permission-set assignments only. Point
readers at role chaining or direct federation for those roles.
