Good advice from Peter at Decentralized TV pertaining to securing your crypto by protecting your phone.
I for one am going to take his advice and make my phone provider REQUIRE my in person attendance before implementing any changes: too much is riding on it not to.
Google authenticator is a must as well.
Another thing I do is refrain from downloading anything on my crypto phone, except from very trusted sources.
Or better yet you can buy a second phone, keep it off line, wifi off, data off, and only activate on trusted wifi connections and only when transacting your crypto.
