This takes David OIDC identity providers used to assume a role must be in the same AWS account as the role. When you delegate permissions to others, use permissions boundaries, which use a managed policy to set the maximum permissions that an identity-based policy can grant to an IAM role. An entity's permissions boundary allows it to perform only the actions that are ID and Role name fields already filled in. Identity-based policies grant permission to the entity, and When a role is deleted, the trust policy of the remaining roles that referenced this now-deleted role will show the unique RoleId it trusted in the Principal element when viewed: Because the policy references a now-invalid RoleID, it cant be modified until the invalid RoleID is removed from it. However, you should use a valid account ID if you use this scenario in your test The Access Key ID and Secret Access Key can only be generated once and must be regenerated if lost.
