Google has added a nifty feature to Chrome for iOS that gives you the option to quickly open external links from other apps using Incognito. It’s especially useful on shared devices.
The default behavior loads links alongside other open tabs where your cookies and account sign-ins are shared. By opening in Incognito, you’re not logged in to anything.
If you enable “Ask to Open Links from Other Apps in Incognito” from Chrome Settings > Privacy and Security, tapping a link in an external app will first take you to a fullscreen prompt.
