Note

Use this checklist to solidify your understanding of Vault’s authentication methods before the HashiCorp Certified Vault Associate exam.

1. Core Purpose of Auth Methods

Validate a client’s identity before granting access.
Issue Vault tokens that are bound to specific policies.
Remember: Auth Methods handle authentication, while policies handle authorization.
Your end goal in any Auth Method flow is to obtain a valid Vault token (unless you already have one).

The image provides exam tips related to authentication methods, focusing on validating identities, issuing tokens, and understanding policies and Vault support. It includes colorful text highlights and a cartoon character in the corner.

2. Know What Vault Supports

No matter which method you pick—LDAP, OIDC, GitHub, AWS, or a custom plugin—the result is always a Vault token. Be ready to answer questions like “Does Vault support X provider?” by understanding every Auth Method at a high level.

Auth Method	Category	Common Use Case
LDAP	Human-based	Centralized user directory
OIDC	Human-based	Single sign-on (SSO) integrations
GitHub	Human-based	GitHub Organization membership
AWS	System-based	IAM role authentication
Azure	System-based	Managed identities for Azure VMs
AppRole	System-based	Machine-to-machine authentication

3. Understand High-Level Workflows

Skim each Auth Method’s flow: how credentials are exchanged, how tokens are returned.
Watch for exam keywords like “frequently rotated”, “existing provider”, or “no static secrets”—these hint at specific methods.
You’re not restricted to a provider’s native method. For example, an Azure VM could use AppRole, OIDC, TLS certificates, or the Azure method itself.

4. Human-Based vs. System-Based Methods

Method Type	Examples	Interaction	Credential Source
Human-based	LDAP, OIDC, GitHub	Manual	User credentials
System-based	AWS, Azure, GCP, AppRole, TLS	Automated	Platform identity

Human-based (interactive): require user input (LDAP, OIDC, GitHub).
System-based (non-interactive): use platform or machine credentials (AWS, Azure, GCP, AppRole, TLS).

The image provides exam tips on authentication methods, distinguishing between human-based (e.g., LDAP, OIDC) and system-based (e.g., AWS, Azure) methods. It emphasizes understanding interactive and complex credential systems.

Master these concepts, and you’ll be prepared to answer any Vault Associate exam questions on authentication methods.
