How to lock WhatsApp on your iPhone to keep snoopers from spying on your texts
IPHONE users can take extra measures to protect their WhatsApp from snoopers, even when their phone is unlocked.
All you need to do is set up an extra Face ID or Touch ID setting.
To set this up you need to head to your WhatsApp settings.
Then click "Account" and then "Privacy".
From here, you can switch on "Screen Lock" with either Touch ID or Face ID.
You'll also be able to pick a duration time for when the ID is required again.
Now whenever you go to open the app, it'll ask you for your prints or a picture of your face to check it's really you reading your private chats.
You can still read and quick reply to messages in your notification window, so the tool isn't foolproof.
You'll also be able to answer WhatsApp calls.
You can always disable all message previews in your iPhone settings.
Anyone snooping on your phone and trying to bypass the new ID setting on your WhatsApp will see a message that says "WhatsApp Locked. Unlock with FaceID/Touch ID to open WhatsApp"
You'll be asked for a passcode to bypass the whole system after several failed attempts.
In other news, iPhone owners are being urged to update their mobiles immediately in order to protect them from a critical security bug.
Samsung has launched a "try before you buy" scheme for its most expensive mobiles to date.
And, Apple is rumoured to be working on a foldable phone to rival Samsung.
