[azure-ad-adal-deprecation]

Hello,

We have developed an application using ADAL libraries, and we have no plan to update this application.

Can we continue using ADAL libraries without migrating to MSAL? How long will this Azure AD (v1.0) endpoint be supported? are there any plans to decommission this endpoint?

    Hello @Bhargave, Shripad ,

    You can continue using ADAL libraries for authentication, but it's important to note that Microsoft has deprecated ADAL. While existing applications using ADAL will continue to work, Microsoft will no longer release security fixes for ADAL after June 30, 2023. This means that your application could be at risk if any security vulnerabilities are discovered after this date.

    As for the Azure AD (v1.0) endpoint, it has not been explicitly stated how long it will be supported or if there are plans to decommission it. However, since ADAL is deprecated and no new features will be implemented, it is advisable to migrate to the Microsoft Authentication Library (MSAL) to ensure continued support and access to the latest security features.
