Entra ID passkeys become default in 2026 as SMS and voice authentication near retirement

Entra ID administrators have two deadlines to prepare for: passkeys will become the default sign-in method beginning September 1, 2026, and Microsoft-provided SMS and voice authentication will retire on February 1, 2027. Organizations should identify affected users now and move them to phishing-resistant authentication before phone-based sign-ins stop working.
