LastPass has 90 days to fix the potential exploit before ProjectZero releases the exploit to the public. The Mac Geek Gab Podcast recommends switching password managers if LastPass has not "patched the hole" in half the time (May 1).
I personally have LP on all my devices, having paid money for the mobile version.
1Password seems to have a stronger reputation from the podcasts and bloggers I follow, but the desktop app was much more expensive than LastPass. Perhaps I'm getting what I've paid for. :(
