I have recently experienced an issue when trying to post a Blog from Windows Live Writer to my blog on Blogger. It didn’t allow me to authenticate, I was keep getting below message,
Solution:-
Done research and found that Google changed their security policy and it blocks access to the blogger from all external tool like live writer or any other tool which can be used to write blog posts. Google is considering all these tools as “less secure”
Please follow below steps to solve this issue,
1. Open https://www.google.com/settings/security from your browser and authenticate with your account.
2. Go to the section Account permissions and click on Settings against "Access for less secure apps"
3. Select “Turn on”.
4. Now try from the live writer it should work 
google seems to have completely disabled clientlogin now workaround listed here

You can use open live writer now which is available from http://openlivewriter.org/. Make sure to uninstall Windows Live writer before installing openLiveWriter.
