This application is a good place to store your web accounts credential.
Access to your keys is protected by a Passcode required when the application starts and after 15 minutes without any user interaction.
If you don't remember your passcode, the unlock procedure should be used, because in case of 5 subsequent unsuccessful, tries the entire keyring data will be wiped out and the initialization procedure will be launched as the first run after the installation.
Personal Keyring is also available on Android.
Enjoy!
