This new security check that comes up before being able to go into the LSF and log in is really strange. What's the purpose?
Not sure what you mean by "security check" as the LSF doesn't have such a thing. If it's a message nagging about insecure logins then that's something being displayed by your web browser. Developers are currently being nagged into providing "secure" versions of their sites (i.e. https rather than http). If you don't want to see such messages there are ways of disabling them, depending on which browser you're using.
