Pros:
The keys we generate are very random and very strong.
When your account is encrypted with a random, strong key, it is very secure.

Cons:
Very difficult to remember.
Very difficult to type until you are used to it.
You can create a Secret Key that is as secure or more secure than the ones we generate.

Our Recommendation: Create a Secret Key of your own that is easy for you to remember and type, but difficult for anyone else to ever guess.
