Children use smartphones, tablets, and smartwatches more than ever, but keeping those devices secure starts with one crucial detail: the PIN. While it may seem harmless to set a simple code like “123456” or a birthdate, these are among the first combinations hackers or curious classmates will try.

A strong PIN doesn’t have to be complicated; it just needs to be smart, memorable, and unique. From choosing 6-digit codes over the basic 4-digit ones to using creative number patterns, building security into your child’s device can be both easy and effective.

Plus, tools like biometrics and strong password generators online can offer added layers of protection. Read on for simple, actionable tips every parent should know to create safer digital spaces for their kids, starting with the PIN.

Best Practices for Generating Safe PINs for Kids’ Devices

When creating a PIN for your child’s device, implement some of the best practices that enhance security. Start by:

1. Use 6 Digits Instead of 4

With a 4-digit PIN, there are only 10,000 possible combinations, but a 6-digit PIN expands this to 1,000,000. This exponential increase makes it considerably harder for someone to guess the PIN through brute force methods. Kids often choose simple or repeating numbers, which can be easily guessed.

By opting for a 6-digit PIN, you add an essential layer of complexity. A helpful tip is to combine two smaller numbers that your child knows well, such as their favorite two-digit number and a memorable year. This method keeps the PIN secure while also making it easier for them to remember.

2. Avoid Obvious Combinations

Even with a 6-digit PIN, choosing obvious combinations can still leave kids’ devices vulnerable. Hackers and curious classmates often start with common PINs, like sequences (123456, 654321) and repetitions (111111, 000000).

These patterns are easy to remember, but they also make it simple for someone to guess. Additionally, using personal information like birthdays, ages, or house numbers might seem convenient, yet it’s a risky choice.

To enhance security, avoid these predictable options. If you’re set on using a meaningful number, consider disguising it by reversing the digits or interleaving it with a random number.

3. Make It Memorable, But Not Predictable

How can you create a PIN that’s both memorable and secure for your child’s device? Start by using math tricks. For instance, multiply your child’s age by their favorite number; it’s unique, yet easy to remember.

Alternatively, consider employing alternating digits like high-low-high-low patterns, which can be fun and memorable. Another effective method is transforming a simple word into a numeric code using a phone keypad; for example, “LOVE” translates to 5683.

These techniques not only play to your child’s memory but also make it challenging for others to guess.

4. Teach Your Child About PIN Safety

While it might seem simple, teaching your child about PIN safety is essential for protecting their devices and personal information. Explain that a PIN is private and personal; it’s not something to share like a snack or toy.

Encourage them to treat it like a secret code that only they should know. Discuss the risks of someone misusing their PIN, such as deleting apps or changing settings without permission. Make sure they know to inform you immediately if someone sees them enter their PIN.

5. Use Device-Specific Features

Using device-specific features can greatly enhance the security of your child’s devices, making it easier for them to protect their personal information.

Modern devices often come equipped with biometric authentication options like fingerprint or face recognition, allowing quick access without needing to remember a PIN. This is particularly useful for younger kids who might struggle to recall their codes.

Additionally, parental controls let you monitor access, screen time, and app usage, ensuring a safer digital environment. Features like remote lock and wipe, such as Find My iPhone or Google’s Find My Device, act as safety nets, safeguarding the device in case it’s lost or stolen.

6. Change PINs Periodically

To maintain the security of your child’s devices, it’s important to change their PINs periodically, just as adults are encouraged to update their passwords. Rotating PINs every 3–6 months greatly reduces the risk of someone deciphering them over time. 

This practice is especially crucial if your child has shared their PIN or used it in public spaces, where it could easily be observed by others. To make this process seamless, consider incorporating the PIN change into a routine, such as at the start of a new school term or after a vacation.

7. Use a Secure Method to Store PINs (If Needed)

Storing your child’s PIN securely is essential, especially for younger kids who may struggle to memorize complex codes. Instead of writing PINs in visible places, which can lead to unauthorized access, consider using a password manager like Bitwarden, 1Password, or Apple’s Keychain.

These tools allow you to store PINs safely and retrieve them when needed. If you’re having trouble creating a secure PIN, utilize a strong password generator online and adapt the result into a 6-digit numeric code that’s memorable for your child.

Avoid These Mistakes

When generating PINs for your kids’ devices, you must avoid certain common pitfalls.

Sharing the Same PIN for All Family Devices

While it might seem easier to use the same PIN across all family devices, this practice can lead to significant security risks. Using a single PIN increases the chances of multiple devices being compromised if one is lost or accessed by an unauthorized person.

Using PINs Tied to Public Information

Using the same PIN across devices can lead to significant security vulnerabilities. If someone knows your child’s birthdate or sees their locker number, they could potentially guess the PIN in just a few attempts. Avoid these choices to enhance security.

Writing the PIN Down in Obvious Places

Many kids fall into the trap of writing their PINs in obvious places, such as on sticky notes or in their school diaries. This habit, though well-intentioned, compromises the security that a PIN is meant to provide. For very young kids, consider securely storing the PIN in a password manager you control.

How often should I change my child’s PIN?

Ideally, you should update it every 3 to 6 months. Regularly changing the PIN minimizes the risk of unauthorized access, particularly if your child has shared it with friends or if you suspect someone else knows it. By enforcing a routine PIN change, you can help instill good security habits in your child.

Additionally, review the PIN’s security whenever your child gets a new device or after any significant app updates. If your child’s device has been lost or stolen, change the PIN immediately.

Can biometrics replace PINs for kids?

Yes, if the device supports it, fingerprint or facial recognition can offer a convenient and secure method for your child to access their devices. These biometric systems can streamline access, making it easier for kids to use technology without memorizing complex codes.

However, remember that a PIN is still necessary as a backup option. Biometric systems can sometimes fail due to smudged fingerprints or poor lighting for facial recognition. Consequently, while biometrics can enhance security and usability, relying solely on them isn’t advisable.

From Convenience to Caution: Striking the Right Balance

To conclude, securing your child’s device with a strong, 6-digit PIN is paramount. Prioritize privacy by practicing proper PIN generation techniques, steering clear of simple sequences and personal identifiers. Regularly refresh the PIN to reinforce security habits.

While biometrics offer convenience, they shouldn’t completely replace traditional PINs. By fostering a foundation of safety and secrecy, you’ll help your little ones navigate the digital domain confidently and securely, ensuring their online experiences remain safe and sound.
