WhatsApp is among the fastest-growing instant messengers out there. It is a social network on its way, and although it is already somewhat secure, some settings will enhance your security and privacy. WhatsApp has built-in end-to-end encryption which is enabled by default and can’t be disabled. This end-to-end encryption ensures only your recipients’ phone can read the message, as well as your voice and video calls.
Checking your Encryption
Although WhatsApp encrypts all chats by default, sometimes you want to double-check. It’s good practice to do that while sharing sensitive information like a credit card number with a trusted contact. To verify the encryption, start a conversation with that contact. In the chat window, tap the contact’s name, and then tap Encryption. You’ll see something like this:
The above image shows the 40-digit pattern. It is your security code, and you can use it to by comparing the digits, asking your contact to scan that QR code, or scanning your contact’s code with the “Scan Code” button. If both match then the encryption is good. It is best to use a different messenger to verify that these numbers match.
Activate Security Notifications
The generation of a new security code happens when a new phone or laptop accesses an existing chat. WhatsApp can, if enabled in the settings, send a notification when the security code changes for that chat. You can then check the encryption with your friend over a different messenger using the method above. It helps ensure the security of the encryption.
This is in Settings > Account > Security
Enable Two Step Verfication
You should use two-factor authentication (2FA) whenever possible. WhatsApp has a form of two-factor authentication within it, through the use of a PIN code. It is a periodic passcode to WhatsApp, which ensures that prevents someone else accessing your data. To activate the 2FA feature, go to:
Disable Cloud Backups
End-to-end encryption is excellent and should be in the standard in every form of digital communication. There is, however, one place where the chats and videos are not encrypted, and that is in the backups. This may affect your ability to use WhatsApp safely. WhatsApp backs up the chat information to either Google Drive or iCloud, depending on your handset. The backup is not encrypted. If you are using WhatsApp for discussions you would rather not have people find out about; you should disable the backup.
To disable the automatic cloud backup on iPhone go to Settings > Chat > Chat Backup > Auto Backup > Off.
On Android go to Menu > Settings > Chat > Chat Backup > Backup to Google Drive > Never.
Lock Down your Privacy
WhatsApp has done a lot for communications security. While it is not the most private messenger out there, it does give users at some control. In the privacy settings, you can update WhatsApp with how you wish your privacy to be set.
Using WhatsApp safely means keeping up to date with security fixes. You should make sure you WhatApp client is updated regularly but only every download from the genuine WhatApp updates.
