Scott has heard about home security apps which allow people to unlock their home via an iPhone, and is wondering how secure they actually are. Leo says that they're likely very similar in technology to garage door openers, so it should be secure because users can set their own password and level of security. Door locks are mere conventions though, and they can be defeated if given enough effort.
George wants to know if LastPass is a good option to save his passwords. Leo says he uses it for everything. He uses it for password protection not only on his PC and Macs, but also his mobile phones. He also uses it to protect confidential information as well. It's free, with a premium version for $12 a year.
Ben is using LastPass and he's wondering if it's secure if he makes up all the passwords. Leo suggests having LastPass generate all the passwords so he doesn't have to make up or input them. It has a built in password generator to help. Also, he should install the browser extension and get the app for his smartphone.
This week, Evernote announced on their blog that they've been hacked. Fortunately, all hackers were able to get was usernames and passwords. So Evernote too the step of resetting everyone's passwords so that they would have to change their password to get online. (this is called hashing and salting).
This is because security in the browser is paramount. Everyone including Firefox, Google, Microsoft and Apple all realize browsers have to be kept up to date. Microsoft has even created a site begging people still using IE6 to upgrade. Chip says he liked the separate search boxes in the older browsers, but Leo says it's not worth the security risk of staying with an older version. Firefox also had a severe problem with memory leaking causing a crash, so updating will fix that too.
