Hi Team, How we can get access token again If access token is expired or want to get new token (refresh token) without customer re-authentication in Msal. Previously we were using adal and below is the code.

AuthenticationContext context = new AuthenticationContext(config.getAzureOAuthAuthority(), true, service); context.setProxy(ProxiedJdkHttpUrlConnectionSource.INSTANCE.getProxy()); Future<AuthenticationResult> future = context.acquireTokenByRefreshToken(refreshToken, credential, null);

I am trying below code but it is not working.

final ConfidentialClientApplication app = ConfidentialClientApplication.builder( config.getAzureOAuthClientId(), ClientCredentialFactory.createFromSecret(config.getAzureOAuthClientSecret())) .authority(config.getAzureOAuthAuthority()) .build(); SilentParameters parameters = SilentParameters.builder( Collections.singleton("https://graph.microsoft.com/.default"), app.getAccounts().join().iterator().next()).build(); CompletableFuture<IAuthenticationResult> future = app.acquireTokenSilently(parameters); result = future.get();
