The GrapheneOS Foundation asserts the software is legal and that it has no obligation to weaken its security protections. The duress password irreversibly wipes the device when entered, and the foundation states data recovery is impossible even for them. The case highlights the ongoing tension between privacy tools and law enforcement access, echoing debates around encryption backdoors. GrapheneOS also notes that its auto-reboot timer and encryption features can protect data without needing to resort to a duress wipe, and cautions users to consider legal consequences before using it. ## Full article daily.dev links to this article rather than hosting it.

Here is what I think probably actually happened, based on the multiple accounts I've read: "Give us the PIN for your phone" "I don't want you to search my phone, and I want to talk to my lawyer" "If you don't comply, you're going to be in a lot of trouble" "Can I please just go, I don't want to answer questions or be searched" "If you don't comply we will seize your phone and detain you indefinitely until we can unlock your phone!" "I want my lawyer." "Just tell us the PIN and you'll be on your way. Otherwise it's gonna be bad." "Look if I have no choice my PIN is 1234, but I don't want you searching my phone without my lawyer present." ... "Hey! We tried to search your phone and the phone wiped itself! You're going to prison for destruction of evidence!" > — [thecrash on hackernews](https://news.ycombinator.com/item?id=49086525) > Intentions matter. If the intent is to trick the officer to enter a PIN code that will destroy potential evidence then it does not matter that you didn't type the PIN code. Your speech is the thing that triggers a series of events that you know will lead to a wipe. Just like you can be charged with destruction of evidence even if you trick someone else to take the action. > — [victorbjorklund on hackernews · 6 comments](https://news.ycombinator.com/item?id=49085775) > > wiping the device before carrying it across the border seems essentially identical to me. On the contrary, there is a huge gulf between these. Providing a fake password that wipes a device while under active questioning is a clear case of providing false testimony. Lying to the police while under investigation is simply illegal, regardless of the thing you're lying about. By contrast, entering the country with a clear device is not a crime under any possible interpretation that I can see. Now, if you are wiping evidence while you know there is an active investigation against you, that may be a crime as well, but it's a completely separate crime and can't be easily judged by an officer that simply finds you with a clean phone. > — [tsimionescu on hackernews · 1 comments](https://news.ycombinator.com/item?id=49086136) > > Could you be charged with destruction of evidence? IANAL but I expect it depends on whether someone thinks they can prove your intent was specifically to disrupt a (legitimate) search. To recycle a comment from 2 days ago, regarding why one might have the duress code written on the phone: > "Your honor, I have the real pin memorized because I use it all the time, but since I can never use the duress code, I had to keep it somewhere handy." > Or > "Pickpocketing and phone-snatching is a real problem overseas, I put it there so that criminal would wipe the phone trying to get in, denying them access to things like my bank account." > Heck, those aren't just plausible, they might be a good idea. > — [Terr\_ on hackernews](https://news.ycombinator.com/item?id=49087019) > Seriously. All of these comments talking about the legality are completely missing the point. At most that indicts the current laws, rather than the person who was illegally and immorally surveilled, searched, detained, coerced, and now harassed through the legal system. Anybody standing on a narrow view of "but this is just the law" while we have an outright hostile federal government that actively hates our individual liberties has wholly lost the plot. > — [mindslight on hackernews](https://news.ycombinator.com/item?id=49087009) **Source threads** - [hackernews](https://news.ycombinator.com/item?id=49085236) · 60 points · 165 comments ## Similar posts on daily.dev - [GrapheneOS: "Apple and Google are gradually…"](https://daily.dev/posts/grapheneos-apple-and-google-are-gradually--m5jit5q02) · Hacker News · 0 upvotes · 0 comments --- Tags: [#security](https://daily.dev/tags/security), [#android](https://daily.dev/tags/android), [#privacy](https://daily.dev/tags/privacy), [#encryption](https://daily.dev/tags/encryption) [View this post on daily.dev](https://daily.dev/posts/grapheneos-defends-data-wiping-function-that-blocked-us-border-search-9s8kbg8lg) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"GrapheneOS Defends Data-Wiping Function That Blocked US Border Search","url":"https://daily.dev/posts/grapheneos-defends-data-wiping-function-that-blocked-us-border-search-9s8kbg8lg","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/grapheneos-defends-data-wiping-function-that-blocked-us-border-search-9s8kbg8lg"},"datePublished":"2026-07-28T16:05:45.382Z","dateModified":"2026-07-30T16:47:13.123Z","description":"GrapheneOS is defending its duress password feature after an Atlanta activist used it to wipe his phone during a US Customs border search, leading to a...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7aa4a577278938eea42fe6bcdaa3fa1a?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/7aa4a577278938eea42fe6bcdaa3fa1a?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Hacker News","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Hacker News","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/hn","url":"https://daily.dev/sources/hn"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/grapheneos-defends-data-wiping-function-that-blocked-us-border-search-9s8kbg8lg","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security,android,privacy,encryption","timeRequired":"PT5M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Hacker News","item":"https://daily.dev/sources/hn"},{"@type":"ListItem","position":3,"name":"GrapheneOS Defends Data-Wiping Function That Blocked US Border Search"}]} ```
