Apple ID verification fails on iPhone 12

Subject: Repeated Apple Account Verification Failed Error on iPhone 12


Hello Apple Support Team,


I am experiencing a persistent Apple Account verification issue on my iPhone 12.


Whenever I try to access certain Apple Account security settings or verify my account password through iPhone Settings, I receive the following error immediately:


“Verification Failed – An unknown error occurred.”


Here is a summary of the issue:



  2. I can successfully sign in to my Apple Account through the official Apple website using the same password.


  5. During the past two weeks, I received two unexpected security alerts stating that my account was locked for security reasons and that I needed to reset my password.


  8. I have already reset my password twice.


  11. I checked my trusted devices, phone numbers, and email addresses. Everything appears correct. No unknown devices are connected to my account.


  14. I have updated iOS to the latest available version.


  17. I have reset Network Settings, but the problem persists.


  20. The verification error appears immediately after entering my correct password, without any noticeable loading time.


  23. My iPhone was purchased second-hand, but I personally signed in with my own Apple Account when I first started using it.

I am concerned that there may be an underlying issue with my account authentication, device authorization, or Apple’s security verification system.


I would appreciate it if your technical team could investigate my Apple Account and determine why verification consistently fails on my iPhone while web authentication works normally.


I do not want to sign out of my Apple Account, disable Find My, or erase my device until this issue has been properly investigated.


Thank you for your assistance.


Best regards

This is a user to user support forum. Apple is not here.


You say, "My iPhone was purchased second-hand, but I personally signed in with my own Apple Account when I first started using it." Was the device properly prepared for resale? See this article about what to do before resale of an iPhone or iPad https://support.apple.com/109511 If that was not done then there could be residual data on the device causing problems.


If you can't connect or sign in to iCloud, read this support article --> https://support.apple.com/HT203512


If using cellular data, try using WiFi instead —> https://support.apple.com/HT202639


"Verification Failed An unknown error occurred. --> In this case https://discussions.apple.com/thread/256214554 the account had been permanently disabled. Again, contact Apple to verify if this is the case.


Otherwise, for generic, numeric, unknown "error”, or simply unhelpful messages I suggest you contact Apple.


This support page has information about contacting Apple support and service ➔ https://support.apple.com/106932 If live support options (chat and/or telephone) are available they will show near the bottom left.

- Telephone numbers may only work when calling from the same country.

- Chat options (telephone numbers appear as active links, not plain text) may depend upon cellular connectivity. If a number shows as an active link, click on it to see additional options.

- If chat is not available on the top level support page, try selecting your hardware and narrow down your issue to see if a support article offers a support link offering chat. For example, the contact support link on this page https://support.apple.com/119902#zerobalance offers a chat link about emptying account balance even on a computer where the top level page does not offer any chat.

With an iPhone, iPad, or Vision, you may be able to chat using the Apple Support App if it is available in your country —> https://apps.apple.com/app/apple-support/id1130498044
