Part 1. Why Does “Passcode Requirement iPhone” Pop Up?

iPhone users often take the Passcode Requirement iPhone popup as a bug, virus, or malware attack. But the truth is the operating system on iPhone is highly protected and efficient enough to prevent any malware, bug, or virus.

There are no definite reasons behind the passcode requirement popup issue. However, we will let you know some possible things that can root this below.

Easy/common Passcode

Are you using a four-digit password or a common combination of digits in the passcode? If so, this could be the reason behind the popup. Some examples of the ordinary passcode are 1234, 1111, 0000, etc. As easy passwords are the common target of hackers, the iPhone recommends you change the passcode for the device's security.

Safari browser

One of the most common reasons behind the passcode issue is the Safari browser. Like any other web browser out there, it saves the cookies and cache data when you visit websites and do searches. These can cause different random popups as well as the Passcode Requirement popup.

Configuration profile

Configuration profiles are used to define or restrict the functionality of a device. If you have installed a configuration profile on your iPhone, it may also cause this prompt message. You can check it by going to the General tab from Settings. You should find the configuration profile under the Profiles and Device Management tab if there is any.


In case you don't know, MDM stands for Mobile Device Management. The MDM-enrolled device is the one that is given to you by the organization you work for. The MDM system can detect if your password on your iPhone is weak and send you the popup to update the password.

iOS bug

iOS system bugs may sometimes cause random issues such as iPhone passcode requirement popping up, iPhone stuck on a black screen, etc.

Contact Your Device Security Service

Many iOS users use third-party security services to make the device more secure. If you use such services, the passcode requirement popup may occur because of their security patch or update.

In this case, it would be better to contact the service provider. They should provide you with the best possible solution to this problem.

Part 3. How to Make a Good Passcode?

Most of us underestimate the importance of a strong passcode. The passcode you are using works as the guard of your iPhone to protect the personal information it’s holding. So, it is imperative to use a strong password to keep your device secured. Here is what you should take into account while choosing the passcode:

  • Choose a lengthy passcode.
  • Include numbers and symbols in the passcode with letters.
  • Mix both lower-case and upper-case letters.
  • Never use your personal information on the passcode.
  • Never use plain dictionary words in passwords.


As you see, several things can cause the passcode requirement popup in your iPhone. You should be able to solve this by following the methods we have discussed above. Also, make sure to change the passcode of your iPhone to prevent this issue from reappearing.
