Forget your password. Forget that dongle that gives you a number every 30 seconds. Get a Yubico (http://www.yubico.com/) YubiKey.
Yubikey is a USB dongle that works with various password managers like Last Pass and Password Safe. That way you don't have to remember your passwords - the Yubico YubiKey does that.
At CES Yubico debuted the NFC dongle (called YubiKey Neo) for mobile devices using Near-Field Communication technology. Simply tap the Neo on the device to get logged into the mobile device.
