Most Common iPhone Passcodes

PeterWallace

Everyone knows it is a good idea to lock your phone in case it is lost or stolen. But is that passcode you picked really secure? The iPhone allows you to pick a four digit code which means there are 10,000 different combinations. If you set your device to wipe the memory after 10 wrong attempts that means you will only have a 0.1% chance of success. Sounds pretty good till you think that there 10 codes that 15% of iPhones are used. With a 15% rate about 1 in 7 iPhones could be unlocked easily.

There was an app called Big Brother Camera Security (Free application that was in the top 25 free apps) that was a security application that would take a picture of someone using your iphone 4 using the front camera. Daniel Amitay the author of the application added some code to record Big Brother’s Passcode entry and send it back to him completely anonymous. (Boy a spy security program spying on you!) He collected 204,508 passcodes before Apple removed the app from the store. He noted several interesting things in the numbers. The top number was chosen by 4.3% of users and the top 4 was 10.8% of users. So a person would have a pretty good odds on getting on the phone.

The top 10 pass codes were (listed in rank order) 1234, 0000, 2580, 1111, 5555, 5683, 0852, 2222, 1212, 1998. Most of the top passcodes follow typical formulas, such as four identical digits, moving in a line up/down the pad, repetition. 5683 is the passcode with the least obvious pattern, but it turns out that it is the number representation of LOVE (5683). What also was found that 1990-2000 all were in the top 50 and 1980-1989 are all in the top 100. This could be passcodes of birth years, graduation years, or anniversary years. With a bit more guessing if the person know you they may have a better chance of unlocking it.

If you are using any of these codes you should change it right way with a totally random number. But remember that this code also may be used for your bank atm card, alarm system, keyless entry to your car and many other sites so they all need to be changed. What this shows is that our days of secure information is limited and we need to search for other ways to secure our data and lives.

Technology in Construction & Manufacturing: Why It’s More Than Just Device Management

January 20, 2026

Modern construction and manufacturing sites are no longer just about heavy machinery; they’re digital ecosystems. Tablets, laptops, IoT sensors, and mobile apps are now essential for everything from blueprint access to production monitoring. These tools enable real-time collaboration, safety compliance, and operational efficiency. But when your workforce is spread across remote job sites or large facilities, keeping these systems connected and secure becomes a challenge. Construction Blueprint & Plan Access: Crews use tablets to view updated plans on-site, reducing errors and rework. Safety & Compliance Reporting: Mobile apps allow instant incident reporting and safety checks. Equipment Tracking: IoT sensors monitor heavy machinery usage and maintenance needs. Manufacturing Production Line Monitoring: Tablets and IoT devices track throughput and detect anomalies. Quality Control: Mobile devices capture and share inspection data in real time. Inventory Management: Connected devices streamline material tracking and reduce downtime. These tools keep projects moving, but only if they’re secure, updated, and accessible anywhere. Why Remote Access Is Critical Construction sites and manufacturing plants often operate in remote or rugged environments. Workers need secure, reliable access to company systems, whether they’re in the field, on the shop floor, or traveling between sites. Without proper management, connectivity issues and security gaps can lead to delays, data breaches, and compliance failures.
