This page aggregates measured, corroborated evidence: donors' iPhones recorded apps contacting this domain, every claim below was reported by separate accepted donations and published under a human verdict (later rows for an approved app inherit its verdict). A contact is a measurement, not an accusation — it does not show what data was sent.

What our research panel found AI-drafted · human-reviewed
We ask several independent AI models the same question and publish their answers separately — cross-vendor agreement is evidence against fabrication, and disagreement is worth seeing. 3 of 3 models answered, overall confidence high. A human reviewed this domain's claims before anything here published.
Anthropic Claude — first-party
login.live.com is Microsoft's own consumer identity/authentication endpoint (Microsoft Account sign-in), so for Microsoft Authenticator it is a first-party contact serving the app's core purpose. First-party authentication traffic is expected functionality rather than a data flow to a third party, so the declared label's omission of it does not indicate an undisclosed flow.
OpenAI — first-party
login.live.com is a Microsoft login domain and is plausibly used for Microsoft Authenticator account authentication. The provided label information does not establish that this contact transmits a data type outside the declared categories.
Google Gemini — first-party
login.live.com is Microsoft's primary consumer authentication service, making this core first-party traffic for Microsoft Authenticator.
