That's a good advice, thank you.

In our approach we do our best to not to affect user experience. E.g. consider an example of a company website with a blog. The company does it's best to engage more audience to their blog, products whatever. I guess quite a part of the audience will be lost due to requirement of authentication on website, which they see first time.

However, for returning, and especially regular, clients I think that is a really simple and good solution.
