[Introduction:]<\/b> <\/p>\n

As part of the Microsoft Secure Future Initiative (SFI) and in alignment with the \u201cSecure by Default\u201d principle, we\u2019re retiring the legacy IDCRL <\/b>(Identity Client Run Time Library) authentication protocol<\/b> in SharePoint Online<\/i> and OneDrive for Business<\/i>. This change helps strengthen your organization\u2019s security posture by enforcing modern authentication standards\u2014OpenID Connect and OAuth\u2014which reduce exposure to outdated and vulnerable authentication methods.<\/p>\n

[When this will happen:]<\/b> <\/p>\n
