Double-check privacy settings on social networking sites.
What's your mother's maiden name? What's the name of the first school you went to? What was your favourite subject at school? What's your address? Birthday? Phone number?
All this information is useful to people who want to steal your identity or break into your online banking. You wouldn't give this information away to a stranger in the street but if you use social networking sites, such as Facebook, Twitter or MySpace, you could be over-sharing personal data.
You may want to think carefully about the information you put into your profiles on sites like this. It is also a good idea that you check the privacy settings on each site that you use to make sure you only share personal information with people you trust.
Please also remember that you must take all reasonable precautions to keep your details safe and prevent any unauthorised use of any cards and security details. If any information forms part of your security details, you should therefore make sure that you do not disclose it to anyone else – see terms and conditions (PDF, 639KB) that apply to your account(s) for more detail.
