Your Security Online

We are committed to protecting your privacy and ensuring that any personal information provided by you is secure.

Online security is our number one priority

There are so many benefits in using the internet. It can be quick, convenient and even fun but, as with most things in life, it’s not without its dangers.

You probably already know a lot about staying safe online but it does no harm to remind ourselves of the steps we should be taking to protect ourselves.

Online security is something that no-one should take for granted. We don’t – it’s our number one priority. And while no-one should lose sleep over it, staying safe online is something that does need some thought.

Follow our simple seven-step guide to staying safe online.

Using our site and security of your information

When you use our site, we ensure that any information you send us is scrambled and can only be translated by us using a secure connection.

The majority of email providers have adopted appropriate security controls to protect your information but we cannot guarantee the security of your specific provider. If you do choose to receive information by email you do so at your own risk. You need to bear this in mind if you ask us to communicate with you in this way. We will never ask you to send us personally sensitive information or security information such as passwords via email.

Other Websites

We have links to other websites, including other members of the Principality Building Society Group, which are not covered by this privacy policy. Other websites' privacy policies may differ from ours and if you access other sites, information may be collected about you in accordance with the privacy policy of the other sites. We cannot accept responsibility for the accuracy or content of any other websites, including those that may have links from this website. In creating hypertext links to any other website, Principality is not recommending these websites.

Keeping your personal information secure

It is important that you take steps to protect yourself against all forms of financial crime. Please take some time to read our helpful advice below on what you can do to protect yourself:

  • Ensure that the equipment you are using to access our online services cannot be overlooked by another person
  • When you have completed your transaction or wish to take a break, log-off from the service and close down your Internet browser
  • Do not use a public computer to access your online accounts because you cannot be certain that the public computer is secure. It could be infected with a virus that will try to collect your password or other personal information
  • Using an email account that is not shared with other family members will help keep your communications confidential

How to protect yourself further

  • Personal firewall software can detect and block abnormal network activity directed at your computer. This activity is usually automated, and as soon as an insecure computer is found it will become a target. “Always-on” (broadband) internet connections are most at risk from malicious scanning
  • Anti-virus software can help to detect viruses. There are 2 main varieties - one type is dependent on the updating of its database of known viruses and the other type (known as "heuristic") is not. You need to keep your anti-virus software up-to-date for it to be effective
  • E-mail content filters can help reduce malicious software, in the form of infected file attachments. Do not open or reply to any e-mail unless you are certain of its source, and you trust it. The Delete key is the best way to deal with suspicious e-mail. Once deleted empty your waste bin to help totally remove it from your computer system
  • Internet website filters can help to block access to offensive web sites and prevent spyware from being installed. Viruses can often be accidentally or unknowingly downloaded from web sites. These viruses can even change a dial-up modem's telephone number so that your internet connection becomes premium-rate.

Using passwords

Never use the same passwords for your online accounts that you use elsewhere. Do not disclose your password to anyone else or write it down.

Email Phishing Scams

We will never ask you to disclose all your security information to us by email. If you receive an email asking you to do this, do not respond, even if it looks like it has come from Principality Building Society. These emails, commonly known as ‘Phishing’ emails, send the same message to as many email addresses as possible.

From time to time Principality may communicate with you by email. Where we can, we will include some more information about you, such as your name to prove our email is a genuine communication. If you receive an email, however genuine it seems, asking you to click on a link to verify your account, confirm your sign-in details, or a similarly worded request, it will probably be a scam and you should delete it. Do not click on the link or provide any of your security details. Genuine emails from Principality may contain links, but they will never take you directly to the online banking log-in page.

If you are ever in doubt about whether an email is genuine, do not click on the link or open any attachments. Please forward it to us at We will investigate every email and ensure that bogus websites are closed down as quickly as possible. Personal information supplied will be held in accordance with our Privacy Policy.

You can read more about phishing.


A trojan is a malicious file, usually disguised as something useful, but when activated, can cause loss, damage or even theft of data. Unlike viruses, trojans cannot replicate themselves so need you to help them spread, by opening an email attachment or downloading a file from the internet.

Once you open the file, the trojan can destroy your computer's functionality - possibly recording your logging-in details. Do not accept files from anyone you do not know, and if you have any doubts, do not open the file.
