Check you have a good passcode
Don’t be that individual who relies on 000000 or 123456 to safeguard their information. Yeah, you ‘re better. A lot better. Go to Settings > Face ID & Passcode (or Touch ID & Passcode on older iPhones), enter your current passcode, then tap Passcode Options to access a set of options. Choose between Custom Alphanumeric Code (the most secure) or Custom Numeric Code (the second best option), or 4-Digit Numeric Code (this last option is not recommended).
Leakage Management
That’s Data Leakage. Take control over how much — or how little — knowledge a locked computer wants you to use. iOS 13 provides the following checks:
Today View Notification Center Control Center Siri Reply with Message Home Control Wallet Return Missed Call USB Accessories
With the exception of Home Control and Wallet, I have everything disabled. The bottom line is that the more the computer and data are protected, the more secure it will be. The USB Accessories feature is particularly useful because if your iPhone or iPad has been locked for more than an hour, it will prevent the Lightning port from connecting to any device. Go to Settings > Face ID & Passcode (or Touch ID & Passcode for older iPhones), and enter your current passcode to take control of it.
Are you lazy, and reused passwords?
If you are using the iCloud Keychain to store web passwords, this can now be used to search for reuse of passwords (which is evil, so don’t!). Go to Settings > Passwords & Accounts > Passwords for the Website & App and authenticate with either Face ID / Touch ID or passcode. Next to any repeated entry you will see a grey triangle with an exclamation mark. Tap Change Account on Website to change email.
Reduce timeout for lock screens to a minimum
The shorter you set the timeout setting for the lock screen (there are options that range from 30 seconds to never), the faster your iPhone or iPad display will need authentication to access it. My advice — never set it to never. None! The auto-lock time can be adjusted by going to Settings > Monitor & Brightness > Auto-lock.
Hide preliminary notification
Prevent potential snoopers from accessing your information by removing samples of the update. Go to Settings > Notifications and then tap Display Previews, and pick Unlocked.
