Apple update looks like Czech mate for locked-out iPhone user

I lost all of my photos when I was a college student too. I was way too irresponsible to actually back anything up. Kind of a bitter lesson.

It’s an annoying workaround, but could he connect a USB keyboard (via a USB to lightning adapter) with the ability to enter the character? Does the passcode screen accept input from attached keyboards?

after Apple removed a character from its Czech keyboard I wonder what the thought process (or perhaps lack thereof) at Apple was. Did no one of the likely-somewhat-large team who did that think "wait, this could lock out our users who may have used that character"? In the immortal words of Linus Torvalds: "WE DO NOT BREAK USERSPACE!" Now one of the ways in might be those companies who claim to be able to break iPhone security for law enforcement and the like, but I'm not sure if they'd be willing to do it (at any price) unless you could somehow trick them into thinking you had some "interesting" data on there...

I used to have an emoji password for my Android phone, and had the exact same issue after a reset! It's an odd but pretty terrible failure mode for locking oneself out...

This is completely unacceptable from Apple. You CANNOT remove a key from the keyboard that's being used as a password.

As a non-English speaker I can really relate to this. I think the real mistake was Apple allowing to enter a non-ASCII password in the first place. E.g. on macOS the password fields have been locked to English character set, and I'm not sure why it changed on iOS.

Apple should get sued for this to oblivion, this is unacceptable.

> Byrne was hoping that the next update, 26.4.1, would introduce a fix for this, but its release this week has not helped. Even if Apple restores the háček in a future update, wouldn't he still need to unlock the iPhone to install it?

> During in-house testing, which involved taking an iPhone 16 from iOS 18.5 to iOS 26.4.1, The Register found that Apple has kept the háček in the Czech keyboard, but removed the ability to use it in a custom alphanumeric passcode. The OS will not allow users to input the háček as a character. The key's animation triggers, as does the keyboard's key-tap sound, but the character is not entered into the string. Sounds more like an actual bug than a decision to change the keyboard layout, if this happens only in the passcode screen?

Well I only use alphanumeric US keyboard standards ever since I found out, that certain characters unique to a language different from yours causes you lock out or massive headaches on a used keyboard with almost no print ink left on the keyboard in a Internet cafe in an other country around 2002. Be aware of characters not passwords. I feel bad for the guy but not really blame Apple here. English is my second language and ANSI etc is following a basic character usage. Everything must boil down to 0 and 1 in the end or American English. It is a de facto standard and maybe knowing about it is as crucial as recognizing the difference between the imperial and metric system before heading for the moon. It is a life saver.

I think the biggest lesson here is to back up. The reason for losing access to the phone is amazingly dumb but it could have fallen down the stairs for basically the same effect. And do your could backups cross-provider. You never know what the "big players" are going to pull, and your lifetime customer value is less than the cost of a single support call.

I assume you can use a physical keyboard on an iPhone like I can on Android via USB? Presumably you could buy a wired Czech keyboard to access the device? Twice I have had the touchscreen fail on Android devices and been able to get what I needed off them using a USB mouse.

Even if he did have a Mac with the continuity feature enabled, I suppose the lock-screen won’t accept a paste from the clipboard of a Mac. (If it did, he could enter the correct passcode in any text editor on his Mac, copy it to the clipboard on the Mac, then paste it into the lock-screen on his iPhone)

there was a time when I used a simple "§" in my password. turned out, some Android keyboards don't have the "§". Since then I play it safe with my passwords, using only characters I don't need a specialized keyboard for

This really reads like a modern Ancient-Greek story about inscrutable gods who suddenly decide to complicate your life for some unclear reason and don't respond to any prayers and rituals. People are afraid of AI, but human organizations can be quite opaque as well. That said, as a Czech, I wouldn't use any accentuated characters in my passwords. Anything beyond 7-bit ASCII is just asking for trouble.

formvoltron

if you remove the hachek, there will be MANY locked out czech users. It's a symbol of national pride!

thephyber

The side of my brain that manages organizational changes wonders: how does Apple, a 50 year old company of tens of thousands of engineers and over a trillion USD market cap, manage to keep feature velocity high while not making more of these types of errors? The bug seems low likelihood but high severity for the few affected users. Other than simply never changing the login keyboard (or any of the keyboard code) or having nearly 100% test coverage, how does a company not accidentally have more of these types of issues?

Majority of California based companies employee English only or English and Spanish speakers possibly with some Indian language as well. This leads to lots of problems when you are bilingual or bilingual in other languages such as German in French. Neither Apple nor Microsoft under this sort of language swapping well. Never mind rarer languages like Czech or Greek.

0x3f

Seems like a front-end bug? So just access the API directly, or ask someone who knows how to do that? Plenty of iOS-focused reverse engineers out there.

"Never do a major OS update on any Apple product" - this is the mantra I am telling myself always.
