I've just requested an account recovering in order to change my mailbox password. I did not remember my personnal infos, so I had to fill a form to assure that I was the owner of my mail account (lastname, firstname, subject of recent emails etc.). It has been validated very quickly and I must say I'm very happy with it.

But there are two points I thought you might be interested with...

Firstly, when I was asked all the questions about recent emails received or sent, my mailbox was opened in another tab (probably because it was previously loaded) so it would have been very easy, for someone hijacking my account, to answer correctly having access to the mailbox. Maybe blocking the access to the mailbox when filling this form might be a solution to this?

Secondly, the subject of the email I received was in (I think) finnish: 

"Olemme vahvistane

It's not a big deal, and the body of the email was in the correct language (french). FYI

Thank you anyway, again it was very quickly managed ;)
