Personal information security
There are a number of ways to protect your personal information and stay safe online.
Use strong passwords or passphrases
Using weak passwords is a threat to your online security. If you use the same password on multiple accounts you risk being hacked.
One of the best ways to stay safe online is to use different strong passwords across your accounts.
You can also use a passphrase. A good passphrase should be easy for you to remember, but hard for someone to guess. It should have at least 14 characters and at least 4 words.
For both passwords and passphrases, the longer it is, the stronger it is. They shouldn’t include any of the following:
- repeated characters
- mixed letters, numbers and symbols
- single words, your address or sequences like 1234
- personal information
- anything you’ve used before.
An example of a good passphrase is ‘horsecupstarshoe’.
You shouldn’t change your passwords often, such as every month, as this leads to poor passwords.

Use secure Wi-Fi networks
Using an unsecure Wi-Fi network can put your personal and financial details at risk.
Public Wi-Fi in shopping centres, hotels, airports and even cafes can be targets for scammers. Scammers can set up Wi-Fi hotspots in order to steal passwords, user names and credit card details.
Try to avoid using hotspots managed by people or groups you don’t know. You should:
- use password protected hotspots
- look for ‘https’ and a padlock in the website and address
- use secure connections
- turn off file sharing and location services
- consider installing a virtual private network (VPN) on your device, which will create a secure connection.
Remember to hide details on your screen when using a computer or mobile device in public. Protect your mobile device with a password or passphrase, and set your device to lock when inactive.
If you’re using a public computer, remember to sign out of your online accounts and close the browser.
Keep software updated
Keep your computer networks and mobile devices secure with security software.
Your mobile devices will have regular software updates. These include fixing vulnerabilities. Updating your software will give you the best protection.
Your computer should always have good virus checking software running. All anti-virus software should both:
- detect and protect against malware, adware and spyware
- provide thorough anti-virus scanning.
Use two-factor authentication
Two-factor authentication is an extra layer of security for your online accounts. It’s an extra step on top of your password that makes it harder for people to access your accounts.
One of the most common uses of two-factor authentication is using a code sent via SMS to your phone.
Using strong passwords as well as two-factor authentication makes it harder for scammers to access your accounts. That is because the person would also need access to something else, like the unique code.

Protect your mail
Some scams start with people taking mail from mailboxes or rubbish bins. Once people get information about the companies you deal with, they can use it as a scam.
They can also get your personal and banking details, or intercept bank cards or cheques. It’s a good idea to lock your mailbox. You can redirect your mail when you move or go away for long periods.
You should also destroy letters and documents that include your personal details before you throw them away.
Use tools and resources to improve your information security
There are a number of useful tools and resources that help you stay safe online.
Password managers are apps that keep your passwords safe. With these, you only need to remember one password, which is the one that opens your password manager.
For landline phones, ask your phone provider if they have a tool that can help you screen calls.
