And defend your privacy
Nowadays, who is it that doesn't use WhatsApp? From sending simple text messages, to sharing photos and files, privacy is constantly challenged.
It is enough, however, to follow some advice for make your Whatsapp more secure:
1) Verify that the conversations are encrypted
Although WhatsApp encodes all chats by default, it is a good idea to carry out a verification anyway. Especially if you are exchanging sensitive data such as credit card numbers or other similar information.
Start a conversation with your contact, and in the chat window, tap your friend's name and then Cryptography. A screen will appear with a QR Code and a 60-digit number, which is the security code. This code can be verified by hand by comparing the figures, or by asking the contact to scan the QR Code, or by scanning our friend's QR Code, all by pressing the button Scan code.
2) Enable security notifications
When a new mobile or laptop accesses an existing chat, a new security code is generated for both mobile phones. And WhatsApp can send a notification when the security code changes. In this way, you can check the encryption with your friend in a different messenger, ensuring its security.
To enable security notifications, open WhatsApp then go to Settings (top right), Account> Security> Show security notifications and move the lever to the right.
3) Enable two-step verification
Two-factor authentication adds a periodic access code to WhatsApp and also ensures that your data cannot be accessed by anyone but yourself.
To activate it, go up Settings> Account> Two-Step Verification> ACTIVATE. Follow the steps to create a six-digit PIN code that you can easily remember. And, importantly, enter your email address to retrieve that code, in case you forget it.
Periodic access code checks are randomized, so it's not quite like putting a password on the chat. The purpose is to prevent anyone from accessing it without your permission.
4) WhatsApp cannot be protected by a password ... or yes?
No, it is not possible to put a password on WhatsApp natively, but you can still use an external app such as Hexlock.
On iPhones, however, there is absolutely no way to protect WhatsApp with a password. Apple does not allow you to do this, either with a code or with Touch ID.
5) Disable cloud backups
Chat encryption is a great thing, except that WhatsApp backs up chats to Google Drive or iCloud. This way, if you reinstall it later you can recover old messages, but the backup is not encrypted.
So if you really care about your privacy, that's something you need to disable. And remember that saving your data on Google and Apple's servers will not protect you from governments that want to snoop into your business.
So, to disable automatic cloud backups do this: su Android, Settings> Chats> Chat Backup> Backup> Never; on iPhone, Settings> Chats> Chat Backup> Auto Backup> Off
6) Protect your privacy
WhatsApp may not be the most confidential messenger out there, but at least it offers the user some degree of control. Take a look at the section Settings> Account> Privacy to see how much is available to you.
You can have anyone, or just your contacts, see your profile photo. Or activate or deactivate read receipts. Or let everyone know what time your last access to the messenger was.
