How secure is a locked phone?

The answer is No, as everyone else has said. There are many ways to bypass an iPhone lock screen however they mostly require the user to have Siri activated on the lock screen which Apple kindly turns on by default.

I work for an Apple competitor so it would be unfair for me to publish any security bypasses to their devices but they do exist. And just for the purposes of being fair, there are also in some cases bypasses for the OS of the lock-screen of the company I work for (depending again on the security settings on the devices). The same can be said about Android as well. So all of the 3 main OS lock screens on about 99% of all devices used worldwide can be trivially bypassed when using the devices in their factory default settings.

Virtually all complex software has bugs or unintended “features”. There are far too many permutations to test and catch all of the edge cases before release. It’s these edge cases that can get exploited, as they were not detected in Unit/Feature and Pre-Release user testing.

Most lock screens are there to stop the “average” person from trying to access a device given that the average person has physical access to the device while the owner has walked away for a short period of time (usually less than 5 mins). If that same person knows what they are doing and has extended access to the device then all bets are off.

Some of these bugs or “features” are also design trade-offs between ease of use and security. A decision is taken on the risk of unauthorized access-VS-ease of use of a feature or usability. For example Android has a nice feature called “trusted devices or places for Bluetooth), the device will auto unlock on connection to a Bluetooth device or when GPS detects a place.

If you want a really secure system then it would be a real pain to use as you would be prompted for creds on virtually every action to ensure you are still the authorized user.

If you’re concerned about security then my advice is to do the following for the main 3 Operating Systems mentioned above

iPhone my advice is to turn off Siri for the lock screen, which will make things much harder for anyone wanting to access your device from a locked state.

Windows my advice is to enable Bitlocker, this is great and will stop most lock screen bypasses.

Android requires more to secure it as it’s the most open in terms of “ease of use functionality” my advice is to turn off most smart lock features like the ones I mentioned above (Trusted Devices and Places), as well as prevent app notifications on the lock screen, Also turn off Assistant on the lock screen and lastly also turn off camera access from the lock screen, and enable an On-Boot security code (not just one for the lock screen) and you should be good.

Like I said you’ll lose some device functionality in your trade for more secure devices, in both Android/IOS.

While in Windows Bit-locker doesn’t disable any functionality, but you’ll need to securely store your key in case there are any fundamental changes to the underlying hard/software settings.
