Blank screen after 1Password autofill on iOS - is this a 1Password side issue?
Hey, I’m an iOS developer at Hornet. We received a user report about a blank screen appearing after using 1Password to autofill credentials on our login screen.
What we investigated:
I did a thorough investigation on our side including runtime swizzling - a technique that allows us to intercept and observe system-level screen presentations at runtime. The result confirmed that the system simply does not call our app-level functions for keyboard-related screens. This means the issue occurs at the keyboard/extension level which, as Apple has designed it, is a completely separate process that app developers have no access to whatsoever.
In the video, the user selected their 1Password credentials however instead of autofilling, a blank screen appeared. I was unable to replicate the issue on my end which leads me to believe it could be related to a slower internet connection or a timing issue on the 1Password extension side.
I also found a similar issue reported to Apple with feedback ID FB9047008 though there is no public record of it.
What 1Password support said:
We reached out to 1Password support but the response was that they are not aware of any platform-wide issue and that they can only investigate further if the affected user contacts them directly — which is not a scalable solution from a developer perspective.
Could a slower internet connection be a factor?
Has anyone encountered this? Is this a known 1Password side issue?
Thanks in advance.
