How do I maximize security and privacy on my iPhone 11 running iOS?

"Hi everyone,

I'm using an iPhone 11 on the latest ios update, and I'm looking for the best steps to keep my device, accounts, and personal information secure.

In the past, I had issues with account breaches and identity theft (email compromise, unauthorized access to accounts, etc.), so I want to make sure my iPhone and Apple ID are locked down as much as possible going forward.

What settings, features, or habits do you recommend for strong privacy and device protection on iOS specifically 11/26 capabilities?

Thanks!"

Probably the weakest aspect is the human factor.

Avoid scams when you use Apple Cash - Apple Support

Identify legitimate emails from the App Store or iTunes Store - Apple Support

Security and your Apple Account - Apple Support

Two-factor authentication for Apple Account - Apple Support - "Two-factor authentication is an extra layer of security for your Apple ID designed to ensure that you're the only person who can access your account, even if someone knows your password."

You express two conflicting thoughts above:

Maximum Security - Maximum iPhone security is achieved using Lockdown Mode.
- Harden your iPhone from a cyberattack with Lockdown Mode - Apple Support
- From the above article: “Lockdown Mode … should be used only if you believe you might be targeted by a highly sophisticated cyberattack, such as by a private company developing state-sponsored mercenary spyware.”
Recommendation - The best security safeguard is your diligence. Recognize and avoid social engineering schemes including phishing messages, phony support calls, and other scams - Apple Support
