Users also had (and still have) the ability to wipe all previously known networks from their iOS devices by choosing ‘erase network settings’ from Settings–>General–>Transfer or reset iPhone(at bottom)–>Reset–>Reset Network Settings.

Security and privacy
Lockdown mode
Lockdown mode is a special mode that, when activated, raises the security to the highest possible level by restricting some features of the OS, apps and web platform, in order to protect users from the rarest and most sophisticated attacks.[12]
Unlike many other security features, lockdown mode is regarded as an “extreme, optional”[12] mode that is not intended to be activated by the majority of users. Rather, it is designed as a defense against advanced malware and mercenary spyware, such as clickless exploits or zero-click attacks, which are often hyper-targeted toward influential individuals such as journalists, diplomats, politicians, activists, lawyers, and high-profile business people.[13][14]
It is possible to disable the Lockdown mode on specific websites and apps by acting from the Safari’s Website Settings and the Lockdown mode's Web Browsing setting.
Passkeys
Passkeys allows the user to authenticate to services that implement WebAuthn across their devices without using passwords. Passkeys are generated by the phone and permission is granted via Face ID or Touch ID.[15]
Safety Check
Safety Check resets all access permissions given to people, apps, and devices for an iCloud account when activated; this is designed to help those in abusive relationships.
Rapid Security Response
Important security updates are now distributed without requiring an entire OS update. Users can optionally remove the security updates, although the standard update will still include the security fixes.[16]
Clipboard security improved
Applications and websites now require permission to copy from the clipboard.
Private Access Tokens
Private Access Tokens are a new technology that replaces CAPTCHAs and helps in identifying HTTP requests from legitimate devices and people without compromising their identity or personal information.[17]
Brand Indicators for Message Identification
Brand Indicators for Message Identification (BIMI) helps users to easily verify authenticated emails sent by brands by displaying the brand's logo alongside the email's header.
iOS 16 requires iPhones with an A11 Bionic[a] SoC or later, which means it drops support for devices with an A9[b] and A10 Fusion[c] SoC, iOS 16 is the first version of iOS to drop support for iPhone without a 3.5 mm headphone jack, officially marking the end of support for the iPod Touch. iOS 16 is the first version of iOS to drop support for an iPhone SE. However, iPhones with an A11 Bionic SoC have limited support[d] while iPhones with an A12 Bionic SoC or newer[e] have full support.[18]
The cutoff for the iPhone 7 and 7 Plus has been criticized due to the iPad 5th, 6th and 7th generations supporting iPadOS 16 despite having similar or even weaker hardware.[19]
