This VA-003 practice question tests your understanding of compare authentication methods. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator wants to allow users to authenticate to Vault using their existing corporate GitHub accounts. Which authentication method should be enabled?
LDAP
Why wrong: LDAP is for LDAP directories.
Okta
Why wrong: Okta is for Okta identity provider.
Username & password (userpass)
Why wrong: Requires local accounts, not GitHub.
GitHub
GitHub auth uses GitHub personal access tokens.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
GitHub
The GitHub authentication method in Vault allows users to authenticate using their existing corporate GitHub accounts by mapping GitHub teams to Vault policies. This is the only option that directly integrates with GitHub's OAuth-based authentication flow, enabling single sign-on without requiring additional directory services or identity providers.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
LDAP
Why it's wrong here
LDAP is for LDAP directories.
Okta
Why it's wrong here
Okta is for Okta identity provider.
Username & password (userpass)
Why it's wrong here
Requires local accounts, not GitHub.
GitHub
Why this is correct
GitHub auth uses GitHub personal access tokens.

Common exam traps
HashiCorp often tests the distinction between 'direct integration' (GitHub auth method) and 'federation via an identity provider' (Okta, LDAP), leading candidates to confuse Okta or LDAP as valid options for GitHub authentication.
Detailed technical explanation
Under the hood, Vault's GitHub auth method uses GitHub's OAuth2 API to verify the user's identity and then checks the user's team memberships against a configured mapping of teams to Vault policies. The token returned by GitHub is exchanged for a Vault token with a configurable time-to-live (TTL), and the mapping is defined via the `vault write auth/github/map/teams/<team>` command. In a real-world scenario, this is ideal for organizations that already manage access via GitHub teams and want to avoid maintaining a separate identity provider.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the VA-003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
