[Question] How to access refresh token

Hi I need to keep refresh token in the database to sync up with client’s inbox. I couldn’t find any legal way to retrieve a refresh token from the IAuthenticationResult. I think up with temporal dirty workaround using reflection:

try {
            //see com.microsoft.aad.msal4j.AuthenticationResult#refreshToken
            final Field refreshTokenField = credentials.getClass()
                .getDeclaredField("refreshToken");
            refreshTokenField.setAccessible(true);
            return refreshTokenField.get(credentials).toString();
        } catch (IllegalAccessException | NoSuchFieldException e) {
            throw new RuntimeException(e);
        }

Is there better anyway to retrieve a refresh token? Serialize TokenCache doesn’t look much better for me.

@sleshJdev Does ‘acquireTokenSilently’ work for your scenario? MSAL doesn’t expose the refresh token but instead takes care of refreshing the access token for you. When you acquire a token with any of the APIs, MSAL will store the refresh token in an in-memory cache, which you can save to disk. AcquireTokenSilently() will first look into the cache, see if you have a valid access token, and if not then will try to refresh the refresh token.
