I don't have my Android phone yet, but I've been happily using SplashID, from Spashdata on the iPhone for about 2 years. They just released v 5.3 of SplashID for Android.
The program also has a mated PC version (not sure if there is an Apple version), which easily synchronizes with the phone, and backups can easily be done on the PC. Data is encrypted, so their is minimal risk of exposure.
