Moving to discussions.

This is a broad topic that should be researched thoroughly, and depends on the platform. For example iOS has the Apple Keychain, which can be used to store mnemonic phrases, private keys, passwords, etc. However, the Apple documentation and general best practices for private key management should be investigated before using even such secure storage solutions.

Opening this up to general discussions though. :)
