What Does Microsoft Authenticator Actually Do?
Microsoft Authenticator generates standard one-time codes, approves Microsoft sign-ins with number matching, supports passwordless access, backs up eligible entries, and registers work or school devices for organization policy.
Workplace registration may grant device information or policy enforcement to an employer. Restoring accounts is not universal, and approving a malicious prompt can still compromise access.
