Azure AD). Using&nbsp;<a href=\"https:\/\/learn.microsoft.com\/en-us\/azure\/active-directory\/develop\/\" target=\"_blank\" rel=\"noreferrer noopener\">Microsoft Entra ID<\/a>&nbsp;as auth platform for your SharePoint Online customizations will provide your applications the most secure, compliant and future proof model. With our continued investment in Microsoft Entra ID, Microsoft is retiring the use of Azure ACS as auth platform for SharePoint Online.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Key Points:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Major: Retirement<\/li>\n\n\n\n<li>Timeline:\n<ul class=\"wp-block-list\">\n<li>Starting November 1st, 2024, new tenants will not be able use Azure ACS.<\/li>\n\n\n\n<li>Starting April 2nd, 2026, Microsoft will remove the ability use SharePoint ACS for existing tenants.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>Action: Review and assess impact<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How this will affect your organization<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If your organization still uses Azure ACS to grant custom developed or third party applications access to SharePoint Online, they will no longer have access after April 2nd, 2026.
