title_body: Is Yoroi secure as a primary wallet?
upvoted_answer: I would argue the Yoroi browser extension is much safer than the iOS application.
  Browser extensions provides double-sandboxing and is considered safer than most of the desktop applications. The browser itself is sandboxed from the rest of your computer and the extensions itself is sandboxes from talking directly to other extensions or to other websites unless you explicitly approves it can do so.
  That being said, the most important element in the this process are your private keys. So, whatever you are using Daedalus or Yoroi, always protect your private keys by using a hardware wallet.
