How to lock your phone against hackers and others.

This week, Whatsapp struck a blow for liberty by adding encryption to the popular messaging service – this foiling the plans of spies, cops and other snoops.
End-to-end encrypted apps mean your messages are safe as they travel – the only person who can read them is the recipient.
But what ELSE can you do to keep the data in your phone safe? Here’s a few tips.

1) Don’t use a four-digit PIN
Your password is the ‘gatekeeper’ to stop people getting into your phone – and four-digit PINs are the least secure option.
Ideally, choose a fingerprint, backed by an alphanumeric password, or, if you simply must, a six-digit PIN.
2) Set your phone to lock after 30 seconds
If someone swipes your phone – or picks it up just after you put it down – they can get in straight away.
Set yours to lock as quickly as your phone will let you.
3) Check if there are ‘spy’ apps on your phone
If you really ARE being spied on – or if your other half is really suspicious – you might want to look for spy apps on your phone.
Telltale signs might be that your phone’s battery runs down, or that it turns on at strange times.
On iPhone, most spy apps tend to require a phone to be jailbroken – so if you find signs yours has been (such as the app Cydia) that’s a warning.
On Android, check your running apps – and look for ones you’re not aware of – as well as scanning for hidden apps in your app directory.
4) Use device finders to remote wipe your device
Your phone in the hands of the enemy? Just remote wipe it.
If you use an iPhone, you should ensure Find My iPhone is enabled.
If Android, use Google’s Device Manager.
5) Encrypt your phone
New iPhones will automatically encrypt the information inside them – so unless your attacker knows your password, you’re safe.

In newer Androids, it’s easy to encrypt your device in Android’s own settings menu – Settings/Security/Encryption.
