I have selected the 2-factor authentication with SMS via mobile phone
for logging in into my Adobe account. This worked 2 or 3 times, but
afterwards I could log in without this 2nd factor. I Think, there is
something going wrong – that shouldn't be the case!(It's damn hard /
impossible to find an e-mail address of a responsible employee. So I
posted this here - knowing that it doesn't necessarily belong here.
Maybe find someone to forward it ...)
