That's why I'm convinced . And by "good" I mean one that syncs seamlessly between your desktop and your mobile devices. If you use one that exists only on, say, your smartphone, how does that help you if your phone goes missing?

I've tried lots of these tools over the years. Right now I'm liking , a cross-platform password manager packed with every feature I consider essential.

For starters, it's available for Android and iOS as well as Windows and Mac. You can sync your mobile devices with your desktop via Wi-Fi -- no physical connection required. And mSecure can also sync with your Dropbox account, effectively giving you a cloud-based backup.

Furthermore, mSecure lives up to its name by employing 256-bit Blowfish encryption, meaning if someone wants access to your info, they'll need an army of servers and several years to get it. The software also offers a self-destruct option, meaning it will wipe the database after five, 10, or 20 failed attempts to input the right password.

Like all good programs of its kind, mSecure can automatically generate secure passwords for you. What it lacks is any kind of auto-fill capability, so at the very least you'll have to copy and paste your passwords into things like Web forms. (That's okay in my book; I always found auto-fill kind of a self-defeating feature.)
