The question asks us to evaluate a statement about the risk associated with turning off a smartphone and whether it hinges on bypassing a lock or entering a PIN to access the device. 
Firstly, consider what the statement is asserting: that the risk of powering down the device is tied to having to bypass the lock or to input a PIN in order to access the device again. This frames the security concern around post-boot authentication and immediate data exposure if the device is off. 
One way to interpret the claim as true is to recognize that many devices enforce authentication after a reboot or wake-up, and an attacker who powers the device back on would either need to bypass a lock screen or present the PIN/credentials before gaining access to content. In general, modern smartphones do protect data at rest with encryption, and unlock requirements help prevent casual access when the device is off or newly powered on. This makes the underlying idea plausible in many setups, especially where strong screen locks or biometric protections are used to gate access after boot. 
However, there are nuances that can complicate a blanket true/false assessment. For instance, some devices may be configured to auto-unlock in trusted environments or when connected to a known accessory, which could lessen the immediate risk of data exposure upon powering up. Other devices might implement secure boot, require a PIN only after specific conditions, or rely on biometric verification to unlock, rather than exposing data freely. These variations mean the precise risk level can depend on device model, operating system version, and configured security settings. 
From a broader perspective, the risk of data exposure when the device is turned off is not solely about bypassing a lock or PIN; it also includes potential vulnerabilities during the boot process, exploitability of unlocked states, and the possibility of hardware-based attacks or recovery options that could bypass some protections. Therefore, the core idea that authentication is needed to access the device after powering on is conceptually sound, but the degree of risk depends on the specific security configuration and protections in place. 
In summary, the statement captures a valid concern about post-boot access requiring some form of authentication, but its absolutism can be challenged by configurable features like auto-unlock, trusted devices, or device-specific security implementations. The reasoning emphasizes that context matters: security is not identical across all devices or settings, and the risk is contingent on how the device is configured to protect data after power-on.
