Most people have thought about this at some point. You may have concerns about people reading your messages, or you could be looking to understand the “magic” behind the dozens of videos about “how to spy on WhatsApp.”
No one knows exactly how many people search for things like “how to read someone’s WhatsApp messages without their knowledge,” but it’s in the thousands. A lot of what’s out there is scams and/or methods that put your privacy at risk.
We, at SEDalerts, believe in transparency. That’s why in this article we’ll talk about actual WhatsApp security methods, show you “secret” methods people use to spy on messages, and teach you how to have the highest level of security on your WhatsApp account.
What is End-to-End Encryption on WhatsApp?
End-to-end encryption (E2EE) is a way to secure messages over an insecure channel. Let’s use an example to make this simpler:
Imagine you have an encrypted message. In order to read the message, you have to decrypt it. Because you can decrypt the message, it’s considered an “end” of the message. In WhatsApp, the “end” is your phone, because it’s the only device that can decrypt the message.
Now imagine you have a message that’s encrypted in a way that no one, not even WhatsApp, can read. Only the end devices can decrypt and read the message. In this case, the “end” is you and the person you’re communicating with. This is End-to-End Encryption.
How Do People Spy on WhatsApp Then?
So far we’ve been talking about the official ways to secure messages on WhatsApp. The good news is, if you’re using the latest version of WhatsApp, you’re using E2EE by default. The bad news is, if you’re not up to date on the latest WhatsApp security features, there are ways for people to attempt to view your messages.
Here are some ways people attempt to violate your WhatsApp privacy:
- Spyware / Monitoring Software: Installing unauthorized software to read messages without your knowledge.
- Outdated Versions: Using an older version of WhatsApp where E2EE might not be properly enforced.
- Modified WhatsApp Builds: Using modified app builds that allow disabling encryption features.
Note: WhatsApp strongly recommends keeping your app updated to the latest version at all times.
Are People Really Reading My Messages?
If you’re using the latest WhatsApp version, your messages are secure. However, here are common ways unauthorized access occurs:
- Physical Access to QR Codes: If someone scans your WhatsApp QR code or takes a photo of it, they can gain access to your linked devices.
- Phone Security Compromise: Without proper verification, someone with access to your phone can bypass setup steps. Enabling Two-Step Verification (a 6-digit PIN) prevents this.
- Physical Access to Your Unlocked Phone: Direct access allows anyone to open the app unless biometric locks are active.
What Happens in the Real World?
When End-to-End Encryption is active:
- Server Hacks: Hackers breaching WhatsApp servers will only see jumbled code.
- Public Wi-Fi Snooping: Sniffing network data using tools like Wireshark yields no readable messages.
- Internal Access: Neither WhatsApp nor Meta employees can read your private messages.
The “Secret Methods” People Talk About (And What’s Really Happening)
1. WhatsApp Web / Linked Devices
What most people think is a “hack” is simply WhatsApp’s official Linked Devices feature (allowing up to 4 devices).
- It is not a backdoor; WhatsApp notifies you whenever a new device is linked.
- You can view active sessions and log out remotely at any time.
- Linking requires biometric verification (Face ID / Fingerprint).
2. Modified 3rd-Party WhatsApp Apps (GB WhatsApp, WhatsApp Plus, FM WhatsApp)
| App | Encryption | Verified? | Risk Level |
|---|---|---|---|
| Official WhatsApp | Full Signal E2EE | ✅ Yes | Very Low |
| GB WhatsApp | Modified / Unknown | ❌ No | High (Data leaks) |
| WhatsApp Plus | Altered source code | ❌ No | High (Account bans, spyware) |
| FM WhatsApp | Third-party APK | ❌ No | High (Adware, trojans) |
Risks of Modded Apps:
- Zero Security Guarantee: Data can easily be rerouted to third-party servers.
- Malware Risk: Trojans and keyloggers are often embedded in APK files.
- Account Bans: WhatsApp actively detects and permanently bans accounts using modified builds.
3. Spyware & Keyloggers
Spyware captures screen output and keypresses directly from the device operating system rather than breaking encryption:
- They do not bypass WhatsApp’s E2EE; they record what is displayed on screen.
- They drain battery, overheat the device, and slow down performance.
- Collected data is often stored on insecure servers, leading to data breaches.
4. Cloud Backups (Google Drive / iCloud)
- Unencrypted cloud backups could theoretically be accessed if your Google/Apple account is compromised.
- Enabling End-to-End Encrypted Backups protects your chat backups with a 64-digit key or custom password, making them completely unreadable to third parties.
6 Ways to Protect Your WhatsApp Account
Step 1: Activate Two-Step Verification
- Go to Settings > Account > Two-Step Verification.
- Tap Turn On.
- Create a 6-digit PIN and add a recovery email.
Step 2: Review Linked Devices Regularly
- Go to Settings > Linked Devices.
- Review all active sessions.
- Tap any unrecognized session (e.g., “Chrome on Windows”) and select Log Out.
Step 3: Enable Biometric Lock (Fingerprint / Face ID)
- Android: Settings > Privacy > App Lock / Fingerprint Lock > Set to Immediately.
- iPhone: Settings > Privacy > Screen Lock > Require Face ID > Set to Immediately.
Step 4: Enable End-to-End Encrypted Backups
- Go to Settings > Chats > Chat Backup.
- Select End-to-End Encrypted Backup and turn it on.
- Create a strong password or generate a 64-digit key (save it in a password manager).
Step 5: Hide Message Previews on Lock Screen
- In WhatsApp: Settings > Notifications > Show Preview > Off.
- iPhone: Settings > Notifications > WhatsApp > Show Previews > When Unlocked / Never.
- Android: Settings > Apps > WhatsApp > Notifications > Hide Sensitive Content.
Step 6: Beware of SIM Swapping and Social Engineering
- Never share SMS verification codes with anyone.
- Set a carrier PIN/Password to protect against unauthorized SIM duplication.
- Verify suspicious requests from friends or family via a direct phone call.
Myth vs. Fact Summary
| Claim / Myth | Actual Reality | Verdict |
|---|---|---|
| “You can hack WhatsApp with just a phone number.” | Requires physical device access, decryption keys, and SMS codes. | Myth |
| “GB WhatsApp lets you read messages safely.” | Modded apps strip security, leak data, and cause account bans. | Myth |
| “QR codes can be scanned remotely to spy.” | Requires physical access to your phone; active notifications alert you. | Myth |
| “Messages can be intercepted on public Wi-Fi.” | End-to-end encryption scrambles data in transit completely. | Myth |
Conclusion
There is no secret or magical way to read someone’s WhatsApp chats remotely. Any app or online tool claiming to offer this capability is almost certainly malicious, designed to steal user data, or scam users.
By updating your app, enabling Two-Step Verification, securing Encrypted Backups, and periodically checking Linked Devices, you can ensure your WhatsApp account remains completely secure.
