Which option is an example of passwordless authentication supported by Microsoft Entra ID?
Show answer and explanation
Answer: C
Entra ID supports passwordless sign-in methods built on possession of a credential plus a local verification step: FIDO2 security keys, Windows Hello for Business, and Microsoft Authenticator phone sign-in. In each case the user proves identity without ever transmitting a reusable account password, which is precisely what removes the phishing surface passwords create.
Why the other options are wrong
- A. A single shared password across employees is one of the worst possible credential practices; it is the opposite of strong authentication of any kind.
- B. Sending your password to anyone — including an administrator — is a credential-harvesting pattern, never an authentication method.
- D. Skipping authentication based on network location removes an identity check rather than adding one; it is an access-trust heuristic, not passwordless sign-in.
