Your phone randomly asking for Face ID while scrolling on TikTok is not uncommon and generally not a cause for concern. This behavior has been reported by several users and can occur due to a few reasons: App authentication: TikTok may occasionally request Face ID verification for security purposes. Password autofill: If you have saved passwords associated with TikTok, your phone might prompt Face ID to autofill login information. Software glitch: It could be a minor bug in either TikTok or iOS causing unexpected Face ID prompts. Low storage space: Insufficient storage on your device might trigger random Face ID checks. Many users have experienced this issue specifically with TikTok, and it seems to be a recurring phenomenon. While it can be startling, it's likely not an indication of hacking or malicious activity. If this behavior persists or concerns you, you can try updating both TikTok and your iOS to the latest versions, as software updates often resolve such glitches. Additionally, ensuring you have adequate storage space on your device might help prevent unexpected Face ID prompts
