For human-based authentication with Azure Active Directory (AzureAD), theOIDC/JWTauthentication method is the best choice. The HashiCorp Vault documentation explains: "The OIDC/JWT auth method is the best choice here. The organization should configure Vault to send authentication requests to AzureAD, which can then validate credentials on behalf of the user." OIDC (OpenID Connect) leverages AzureAD as an identity provider, allowing users to authenticate via their AzureAD credentials in a secure, human-friendly manner.
Oktais a separate identity provider, not directly tied to AzureAD.Active Directoryauth is deprecated and less suitable for cloud-based AzureAD integration.UserPassuses a local Vault-managed username/password, not external AzureAD authentication. Thus, A (OIDC/JWT) is correct.
