Passphrases are the more secure version of passwordsÂ
Passphrases are made up of four or more random words making them longer than a traditional password. This makes them harder to guess but easy to remember. 
Changing your passwords to a passphrase is a great way to improve your cyber security.

Before you try out passphrases, have you set up MFA?
Multi-factor authentication (a combination of something you know, something you have or something you are) is an effective way to protect your accounts against unauthorised access. However, where multi-factor authentication is not available, a strong passphrase is your best defence. 
When you choose your passphrase, make it:Â
Long
The longer your passphrase, the better
A good passphrase is made up of four or more random words. Sentences don't make great passphrases as they can be easier to guess. For example, it is predictable to have spaces between words, a capital letter at the beginning and punctuation at the end. Using a mix of random words is far more unpredictable and makes stronger passphrases.
Unpredictable
The less predictable your passphrase, the better 
A good passphrase is made up of four or more random words. Sentences don't make great passphrases as they can be easier to guess. For example, it is predictable to have spaces between words, a capital letter at the beginning and punctuation at the end. Using a mix of random words is far more unpredictable and makes stronger passphrases.
Unique
Don’t recycle your passphrases 
Use different passphrases for different accounts. Your Facebook password should be different to your email password and so on.
