TikTok is blaming a bug that prompted the app to ask iPhone users for their passcode for unclear reasons, PCMag reported.
The video-sharing said it has since fixed the error, promising that "people won't see the prompt going forward."
TikTok assured that only a "small number of people" were affected by the bug and that "neither TikTok nor our US security partner was able to collect or access people's iOS passcodes" during the error.
The Android version of the app was unaffected.
TikTok Users Get Unsolicited Passcode Requirements on iPhone App
The statement came after several users complained that a prompt was suddenly popping up, requiring them to "enter iPhone passcode for 'TikTok'," when launching the app. The prompt itself can be canceled, and the app will function normally.
Many users accused the app of tracking its users in the US, knowing that the Chinese-based company ByteDance owns the app.
The issue was first noticed by Reddit users last November but has only garnered mass attention this month.
It is worth noting that the error came following a security patch by Apple on its iOS devices to improve the device's safety against thefts and robberies.
This coincides with TikTok's statement that the passcode is used by iOS to "help verify user identity."
Apple is set to fix the issue by adding a new "Stolen Device Protection" setting in the upcoming iOS 17.3 update.

How Good is Apple iOS Security System?
While all operating systems have their flaws and vulnerabilities, Apple's iOS can be considered more secure than the Android OS.
Apple's operating system is equipped with a built-in encryption system and a hardware-based security chip to protect user data even if the main processor is compromised.
Apple also has a tight grip on its App Store, making it difficult for bad actors to inject malware and spyware into apps uploaded on the platform.
The tech giant also provides regular update checks to address detected issues on the device to provide better security.
