How safe is the Yield app?

I'm considering investing in the Yield app, but I want to make sure my funds are secure. Can you tell me more about the safety measures put in place by the Yield app to protect user funds? Are there any risks associated with using the platform that I should be aware of? I'm particularly interested in the security of their storage solutions and whether they have any insurance policies in place to cover potential losses. Additionally, how do they handle user authentication and authorization to ensure that only authorized users can access my account?
