Caveat – this is a more in-depth follow-up to an article we wrote on WhatsApp last year (1)
WhatsApp (2), owned by Meta, is one of the most popular free end-to-end encrypted messaging apps used by youth today, second only to Snapchat. It supports text, voice, video calling, and file sharing, and has a wide range of privacy settings. While many of its features are designed to offer user control and confidentiality, they can also be misused in ways that place children and teens at risk. As a parent or caregiver, understanding how these features work, and how to have conversations with your child about them, is key to fostering safer online experiences.
Disappearing Messages: A False Sense of Security in Vanishing Conversations
WhatsApp’s disappearing messages feature allows users to set their messages to delete after a specific time such as 24 hours, 7 days, or 90 days. While this can seem like a positive privacy feature, it also poses risks. Young users may feel emboldened to share sensitive or inappropriate content under the illusion that it will be gone soon. Unfortunately, disappearing doesn’t mean invisible, messages can still be screenshotted, forwarded before they vanish, or even recorded with another device. Predators or bullies may also use this feature to target youth without leaving a trace. Parents and caregivers should remind children that vanishing messages are not a guarantee of privacy or safety.
The “View Once” Feature: Private Sharing That Can Be Captured Forever
The “View Once” feature allows photos and videos to be viewed a single time before disappearing. While it may seem secure, this tool can easily be misused. Youth might feel pressured to share intimate or sensitive images, thinking they can’t be saved, but a recipient can still take screenshots, use a second device to record the content, or find other workarounds. This feature is often exploited by online predators who manipulate young people into sending explicit content. It’s critical to help your child understand that digital media, once sent, is never truly under their control again.
“Everyone” Chat Groups: Hidden Dangers in Massive Conversations
Public WhatsApp groups, some with up to 1,024 members, can be created or joined by anyone. Youth are often unknowingly added to these groups, where they may be exposed to explicit, violent, extremist, or otherwise inappropriate content. These spaces are rarely moderated and can be a haven for adult predators or scammers targeting vulnerable members. It’s important for parents and caregivers to regularly check which groups their child is part of, advise them to leave any unfamiliar chats, and show them how to block and report harmful content or users.
Status Updates: Disappearing Posts, Persistent Exposure
WhatsApp’s Status feature lets users post text, images, GIFs, and videos that vanish after 24 hours, similar to Snapchat or Instagram Stories. However, statuses are visible to anyone in a user’s contact list, including those from shared group chats. This can result in unintended exposure and unwanted interactions. Replies to status updates also open direct chat windows, making it a channel for strangers to initiate contact. Parents and caregivers should encourage their children to review and tighten their status privacy settings, and discuss the risks of sharing content, even if it’s set to disappear.
Channels: Broadcast Features That Can Spread Misinformation or Harmful Content
WhatsApp Channels allow individuals, influencers, or organizations to send one-way updates to large audiences. While useful for following brands or community groups, these channels can also be misused to distribute misinformation, propaganda, or disturbing content. Since anyone can create a channel, some may impersonate legitimate sources to gain followers and trust. Youth could end up consuming or sharing harmful ideas without even realizing it. Parents and caregivers should review which channels their child follows and have ongoing conversations about evaluating the credibility of digital content.
Chat Lock: Hidden Conversations that Can Conceal Harm
The Chat Lock feature lets users hide specific conversations behind an additional layer of security like a password, fingerprint, or facial recognition. Locked chats are stored separately and are invisible on the main chat screen. While this may enhance privacy, it also enables secrecy. Children can use Chat Lock to hide interactions with strangers, cyberbullies, or others who may be causing harm. Even if you have access to your child’s phone, locked chats remain out of view. It’s essential to have trust-based discussions about why and when to use these tools, and the importance of transparency in online interactions.
Advanced Chat Privacy: Controlling What Leaves the Conversation
With Advanced Chat Privacy, WhatsApp allows users to limit how their messages can be used outside of the platform such as disabling options like exporting chats, saving images, or using AI tools to analyze messages. This can be a powerful feature for protecting sensitive conversations, such as those involving mental health or peer support. However, it can also be used to hide inappropriate or unsafe exchanges. As with any privacy tool, how it’s used matters. Parents and caregivers should explain to their children that real privacy also comes with responsibility and that these tools should not be used to conceal harmful behaviour.
PIN Lock: Privacy that Can Lock Out Parental Oversight
The PIN Lock feature allows WhatsApp accounts to be secured with a six-digit PIN or biometric login, even if someone has access to the phone. While designed to protect user accounts, this feature can also be used to prevent parents from reviewing their child’s chats. If the PIN is forgotten or not shared, even account recovery becomes difficult. It’s important to discuss why PINs should be used responsibly and why parents and caregivers may need access, not to invade privacy, but to ensure safety in times of concern.
Backup Settings and Cloud Vulnerabilities: Why Cloud Doesn’t Mean Safe
WhatsApp messages are encrypted during transmission, but not all backups are. If a child enables backups to Google Drive or iCloud and doesn’t activate the “End-to-End Encrypted Backups” option, those messages can be accessed if the cloud account is compromised. Many young users mistakenly assume their chats remain secure just because the app uses encryption. Parents and caregivers should help their children enable this feature through Settings > Chats > Chat Backup > End-to-End Encrypted Backup to ensure that both conversations and backups are equally protected.
Contact Visibility and Hidden Numbers: When a Phone Number Becomes a Doorway
Unlike platforms with usernames or handles, WhatsApp relies directly on phone numbers. This means anyone with your child’s number can find and message them, even without a mutual connection. This setup removes an important layer of privacy and increases the likelihood of contact from strangers. Parents and caregivers should talk to their children about sharing their phone number only with trusted individuals and using the “Block” and “Report” features if they ever receive uncomfortable or unsolicited messages.
File Sharing Risks: Malicious Documents, Links, and Apps
WhatsApp supports the transfer of various file types including documents, PDFs, and even APK files (Android apps). While this can be helpful for school or collaboration, it also opens the door to malware, phishing links, or explicit content. Malicious files can be disguised to look harmless and may be sent even from a hacked friend’s account. Parents and caregivers should teach their children to never open files or click links from unknown senders and to always verify before downloading anything, even from familiar contacts.
Impersonation and Spoofing: When Familiar Faces Aren’t Who They Seem
Because WhatsApp users can freely change their profile name and photo, it’s possible for scammers or predators to impersonate someone your child knows. Some even spoof phone numbers to make their identity seem more convincing. This tactic is often used in scams or grooming attempts. Encourage your child to be cautious, even when a contact seems familiar, and to confirm identity through voice or video calls before engaging in sensitive conversations.
Psychological Manipulation: The Emotional Weight of Reactions and Read Receipts
WhatsApp’s social features, such as emoji reactions and read receipts, can have unexpected emotional impacts on youth. Being left “on read” or receiving a cold emoji can spark anxiety, insecurity, or peer drama. These seemingly minor signals can contribute to larger emotional stress, especially in peer dynamics. Help your child manage this pressure by showing them how to disable read receipts or mute reaction notifications. Most importantly, keep communication open so they feel comfortable discussing emotional challenges tied to digital interactions.
Cross-Platform Tracking: What Meta Sees Beyond the Messages
Though WhatsApp’s messages are encrypted, the app still shares metadata, like usage patterns, contact connections, and behavioural signals, with its parent company, Meta. This information can be used across Facebook and Instagram to personalize ads or suggest content, creating a broader digital dossier that most youth are unaware of. Because this app is free, this is how they make their money! Talk to your child about how their online activity is tracked and used, and why understanding data trails is an essential part of being a responsible digital citizen.
Scams, Chain Messages, and Misinformation: Fear-Based Manipulation Tactics
WhatsApp is a breeding ground for chain messages and emotionally manipulative scams that prey on younger users. Messages warning of account deletions, fake giveaways, or threats unless a message is forwarded are common and convincing. Youth may panic and comply without thinking critically. Parents and caregivers should encourage a healthy dose of skepticism and remind their children to delete or report suspicious messages rather than responding or resharing them.
In-App Monetization and Business Accounts: When Conversations Become Commerce
Some WhatsApp Business accounts are used by influencers or online sellers to market products and services to young users. These interactions may include external links, personal data requests, or pressure to make purchases. Even though WhatsApp isn’t designed as a marketplace for youth, monetization efforts are increasingly common. Help your child recognize these tactics, understand the risks of digital spending, and avoid sharing personal information with anyone soliciting sales online.
The best way to keep kids safer on WhatsApp, or any digital platform, is through open and ongoing communication. Talk to your child regularly about how they use the app, what features they like, and what potential dangers they may not be aware of. Stay engaged by reviewing their contacts and group memberships together. Adjust privacy settings as a team so they understand what each one does and why it matters. Set clear expectations around when and how WhatsApp can be used, and who they can communicate with. If location sharing is enabled, we would recommend to turn it of, or at the very least make sure it’s only shared with trusted people.
WhatsApp, like many digital platforms, is a powerful communication tool that offers both opportunities and challenges for young users. Its wide range of features, from disappearing messages to location sharing, can support privacy, connection, and convenience. But when misunderstood or misused, these same tools can expose children to risks including bullying, exploitation, and harmful content.
The key takeaway for parents and caregivers is that technology itself is not inherently dangerous, but the way it’s used can be. Rather than defaulting to fear-based reactions or strict bans, the most effective approach is one grounded in education, open dialogue, and mutual trust. By understanding how WhatsApp works, staying informed about its features, and discussing these tools with your child, you can foster a sense of digital responsibility that lasts far beyond a single app.
This isn’t about spying or control, it’s about partnership. Youth and teens are growing up in a connected world that requires new skills and boundaries, and parents and caregivers have an essential role to play in helping them navigate it safely. Teach your child that online actions have offline consequences, that privacy isn’t guaranteed just because something “disappears,” and that it’s okay to ask for help when something feels wrong.
Staying involved, asking questions, setting expectations, and modelling thoughtful digital behaviour all go a long way in building your child’s ability to make safer, smarter choices online. WhatsApp will continue to evolve, and so will the challenges and benefits it presents. But with a proactive mindset and ongoing conversations, you can help your child use the platform in ways that support connection, not compromise safety.
Note – for youth and younger teens, we would recommend the Kinzoo messaging app as the preferred way for them to communicate with friends and family. This app is fully scaffolded with safety and security by design for youth, and they do not sell or monetize any personal identifiable information about you or your child to any third party. (3)
