Link: I use a duress PIN to protect my data - here’s how it works and why everyone needs one

Our smartphones are packed with sensitive data, protected by PINs and biometrics. Yet, the thought of this data falling into the wrong hands is unnerving.

GrapheneOS provides a unique security feature for such scenarios: a duress PIN that wipes the device clean. Setting a duress PIN gives users like me peace of mind, knowing their data can be securely erased in emergencies.

The duress PIN doesn't just lock the phone; it triggers a silent, irreversible factory reset and deletes encryption keys. This feature ensures that sensitive data remains inaccessible even during physical possession of the device.

GrapheneOS's implementation of the duress PIN is subtle, with no signs that a wipe was user-intended. Although professional attackers may be aware of this feature, its quick activation still effectively protects data.

Real-world applications of the duress PIN could be in situations like muggings or encounters with law enforcement, where users can instantly neutralize data access. While some might see it as extreme, it's a critical option for those facing potential data theft.

While Android may never adopt GrapheneOS's extreme security measures, features like a decoy PIN could offer users a less drastic form of data protection. As it stands, Android's Lockdown mode offers a basic level of security against coercion, but for full data erasure, GrapheneOS's duress PIN is unparalleled.
