Smartphone security basics — protecting the device that holds your keys, vault, and ID in one

A phone concentrates 2FA, email, banking, and ID into one single point of failure. The real defense isn't a security app: (1) a strong lock + short auto-lock (the passcode is the encryption key); (2) automatic OS/app updates; (3) official store + permission review; (4) set up remote lock/wipe in advance; (5) keep a backup of your 2FA. iOS/Android already encrypt and sandbox by default.
