If you're using the free version of LastPass to guard your passwords, you can now access your vault through the mobile app for free. Previously, a subscription to LastPass Premium, which is about $12 per year, was required to use the service outside of desktop browser extensions and the website. The subscription service still exists, but for its other benefits, like sharing your vault with up to five other users, two-factor authentication through YubiKey, or securely storing 1GB of files (which could be good for things like encryption keyfiles to personal web servers).
The native Windows “LastPass for Applications” is still Premium-class, though.
If you are still interested in LastPass Premium, they are participating in the Humble Lifehacker Software Bundle. Users who do not currently have LastPass Premium, who also pay more than (currently) $7.64 USD, will get 12 months. They will also get DisplayFusion and CyberGhost VPN, as well as everything in the $1 tier, like a couple of Stardock enhancements for Windows.
