Learning to code is a wonderful use of screen time, but it often comes with going online: looking things up, watching tutorials, sharing a finished project. A few steady habits keep children safe without turning the internet into something to fear.
This guide is general advice for families. It is not legal or professional safeguarding guidance, and rules differ between places and between platforms.
Start with the conversation
The strongest protection is a child who feels able to tell you when something feels wrong. A few ideas:
- Say clearly and often: "You will never be in trouble for telling me something strange happened online."
- Ask open questions: "Seen anything funny or weird today?"
- Stay curious about what they are making, so talking about their online life feels normal.
Personal information stays private
Teach a simple rule: a username is not your name. Children should not share:
- Their full name, address or school
- Phone numbers or email addresses
- Photos that show their face, uniform or street
- Passwords, ever, even with friends
When choosing a username for a coding site, pick something that does not include a real name or birth year. Something like "BlueRocket" is perfect.
Passwords
- Make them long. A short phrase of several random words is better than a short, complicated one.
- Use a different password for each important account.
- A parent can help store them, for example in a password manager.
- Passwords are never shared with other children, even best friends.
Sharing projects
Showing off a finished game or animation is a great motivator. Think together before sharing:
- Who will see it? Family only, or anyone?
- Does it show any personal information, such as a real name in the credits or a photo?
- Are comments turned on, and who is watching them?
Choose platforms with age-appropriate settings and read their rules together. A good service for children should explain clearly what it does with their information. If you are comparing products, our checklist for choosing a coding app for kids lists questions worth asking.
Strangers and chat
If a coding platform has chat or comments, children should know that people online are not always who they say they are. The rules to teach:
- Do not chat privately with people you do not know in real life.
- Never move a conversation to another app at a stranger's request.
- If anyone asks for personal information, gifts or secrets, stop and tell a trusted adult straight away.
Downloads and links
Children should ask before downloading programs or clicking links in messages. Free "cheats" and "mods" are a common route for harmful software. Coding can be done safely in a browser without installing anything.
AI helpers
Chatbots can be useful for explaining ideas, but they can also be wrong and should never be given personal details. See using AI chatbots safely with children.
Balance matters too
Healthy habits include time away from screens, which we cover in screen time and coding: how to balance.
When something goes wrong
If your child sees something upsetting or makes a mistake online, stay calm. Thank them for telling you, take screenshots if helpful, block or report the account on the platform, and seek further help from your local child safety resources if needed. Responding with kindness ensures they will come to you the next time.
