UPDATE: As of June 2, everything is working again. That was an amazingly fast fix given how low priority Blogger has been to Google and Live Writer to Microsoft. Didn't see an update to Live Writer, so I suspect that this is Google's initial fix.
Original Post:
As of May 26, Google changed the login method for external software to access Blogger, cutting it off from all offline editors other than Blogger's default browser editor. Since many of us use Microsoft's Windows Live Writer 2012 to create our posts, this has been a disaster. If you are like me and use a lot of inline images, this is especially problematic since the default editor is terrible at handling images.
Google blames Microsoft:

Hi everyone,
We
appreciate you coming here and letting us know about this issue. It
looks like this error is a result of an authentication problem between
Google and Live Writer. A long time ago, we announced
we were deprecating our old authentication system and we encouraged
developers to move to the new one (OAuth 2.0). It seems that Live Writer
is still using our old system, which is causing the issue. We are
currently looking into it, but we suggest that users also reach out to Microsoft to report the issue.
Thanks,
Blogger Suport Team
p.s. please disregard the previous official announcement.

However, all other blog editors are affected, such as Raven, Blogjet, and BlogFire. Until one or more of them change over access methods, posting to Blogger will be a great deal more difficult given the Microsoft ceased development of Live Writer in 2012.
In my case, it may prevent the movie review I finally finished writing today from ever being posted, since I can't get the images to work properly with the default editor. Short of learning to hand code HTML image sizing, it isn't happening for me.
So I have to wait for some kind of fix from somebody. If that doesn't happen, it will be time to explore Wordpress to see if it can replace Blogger for me. Otherwise, I may stop blogging altogether.
This is more than annoying.
