EVERY iPhone has the ability to instantly protect you from countless hack attacks.

It's all thanks to a built-in iPhone password manager – automatically blocking some of the most common cyber-schemes.

It works using two clever features: iCloud Keychain and Safari Strong Passwords.

Both iPhone hacks are free to use, and ignoring them could cost you dearly.

We're constantly told to choose complicated passwords – but that's difficult with so many accounts.

iCloud Keychain remembers the passwords you type on your iPhone, encrypts them, and stores them in the cloud.

So you can choose very strong passwords for websites and apps without having to remember them – your phone will simply enter them for you at log in.

This is one of the best defences against hackers.

"iCloud Keychain remembers things so that you don't have to," Apple explains.

"It auto-fills your information – like your Safari usernames and passwords, credit cards, Wi-Fi networks and social log-ins – on any device that you approve.

"iCloud Keychain stores your passwords and credit card information in such a way that Apple cannot read or access them."

And the Safari web browser now has a special feature called Strong Passwords.

When you sign up to a service on Safari, you'll get an option to use an auto-generated password that's very difficult for hackers to crack.

This password is automatically saved in your iCloud Keychain so you don't even have to remember it.

You can also add passwords you already have into the Keychain.

But one of the best features is the password re-use alert.

It's important to never use the same password on multiple accounts. If you do re-use passwords, hackers who break into one account can then get access to others.

Your Safari Saved Passwords will alert you when you have two passwords that match, and suggest a change for you.

First, you'll need to make sure you're using an Apple device running iOS 7.0.3 or later, or OS X 10.9 or later for Macs.

On your iPhone, iPad or iPod Touch, follow these steps:

For Mac devices, here's what you need to do:

On an iPhone with iOS 11 or later:

On an iPhone with iOS 10.3 or earlier:

On a Mac with OS X Mavericks 10.9 or later:

Apple has even gone one step further – getting rid of passwords entirely.

It's called Passkeys, and it was added in the latest iOS update, so first check if you've got iOS 16 by going to Settings > General > Software Update.

Instead of signing up (or logging in) to a website using a password, you'll use a Passkey.

This is a digital key that you don't have to remember.

And you simply authenticate who you are using your fingerprint (Touch ID) or face (Face ID) on an iPhone or Mac.

It'll be just as quick to log in, and means you'll have a login that simply can't be guessed or leaked.

Your Passkeys are stored on your devices, but will sync across multiple gadgets using Apple's iCloud Keychain – which already exists to track passwords.

Nobody can read your Passkeys, Apple included.

And it means you can't be tricked into handing over a password through phishing – because you won't have any information to hand across.

The ultimate plan is to allow Passkeys to work on non-Apple devices too, including Windows laptops and Android phones.

Microsoft and Google have both been developing passwordless systems for years.
