Logging in to Hive require the use of keys not just username and password. The keys gives you ownership of your account, the platform or anyone else has no access to your account even if you stop being active today and come back a year later, as long as you have your keys you can access your account. But if you lost your keys you lose your account.

Because of that difficulty in the use of keys especially how to get it during sign up, inleo introduce the keystore account which use file instead of keys. It makes it easier to sign up and sign in, and also to not lose it.
