Miles & More (Lufthansa, Austrian, Swiss, and other partners) - Is milesandmore-aktionen.de a valid link

is http://www.milesandmore-aktionen.de/mymiles/page-1.html?l=de a valid link.

Why do i have to enter my pin,... with this information someone could withdraw all my miles...

That website is operated by the ad agency Young Rubicam for M&M and is legit.

And since you just seem to have entered M&M I bet you won't have much of a balance :-).

But it still makes you wonder why they would need the PIN... Any insight on this?

HTB.

There was already sometime ago a promotion where you had to enter your PIN. I don't like this either and stay away from these promotions. It is bad business practice and a security risk to ask someone for his PIN, Password.

what promo is this anyway?

As a new M&M member you get 50% more award miles for the first 4 r/t flights within 3 months after registration.

This is the mymiles promo for new members who get a boarding pass mailed to them with the link. Who knows why they want the PIN.

This may be a bit far-fetched, but as it arrives with the first M&M card, I guess it's one way to divert the user's attention to the existence of the PIN and stress its importance. I really can't come up with anything better, heh.
