the original settings for a protected identity are:
X "Block spam with safe emails"
X "Make me a new password"
However, the identities set up as default are there for you to experiment with and play around with the settings. Feel free to create your own and create new Identities with different combinations of information you'd like to submit such as:
1. an identity with a valid work address but protecting your work email from spam
2. an identity with completely made up information and protecting both your email and your real phone #.
3. an identity with your real home address and credit cards (useful for booking travel online where you need your real info)
