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

To improve application security, Microsoft Entra ID will enable App Instance Lock by default for newly created applications. This change prevents sensitive application properties from being modified outside the application\u2019s home tenant, reducing the risk of unauthorized changes that can lead to application compromise. Based on our data analysis, we do not expect this change to cause customer impact. App owners or administrators in the application home tenant can still disable App Instance Lock for specific applications if their scenario requires updates to protected properties in other tenants.<\/p>\n

<\/b><\/p>\n

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

General Availability (Worldwide): <\/b>We will begin rolling out in early June 2026 <\/b>and expect to complete by late June 2026.<\/b><\/p>\n
