Previous distributions of `@azure/identity` included an optional dependency on `keytar`, which caused issues for some users in restrictive environments. Version 2 of Azure Identity for JavaScript now also depends on the latest available versions of `@azure/msal-common`, `@azure/msal-node`, and `@azure/msal-browser`. Our goal is to always be up-to-date with the MSAL versions. -All credentials provided in version 2 of the Identity package for Node.js now make use of the latest `@azure/msal-node`. `InteractiveBrowserCredential` now uses the latest `@azure/msal-node` on Node.js and the latest `@azure/msal-browser` on the browser. - -Relying on the latest versions of MSAL comes with many benefits, but it has some considerations: - -- For every new instance of all of the updated credentials, now they will do a first request to discover relevant endpoint metadata information from Azure. -- On the browser, the `InteractiveBrowserCredential` will now use the [Auth Code Flow](https://docs.microsoft.com/azure/active-directory/develop/v2-oauth2-auth-code-flow) with [PKCE](https://tools.ietf.org/html/rfc7636) rather than [Implicit Grant Flow](https://docs.microsoft.com/azure/active-directory/develop/v2-oauth2-implicit-grant-flow) to better support browsers with enhanced security restrictions.
