Do I need to change all my passwords after data breach?
Q Have I been Pwned? (https://haveibeenpwned.com, see screenshot below) advised me that 284 million email addresses and passwords, including mine, have been part of a data breach. Their advice is to change my passwords. However, I’ve not heard from any organisations who may hold my data so I have no idea which passwords need changing. Changing over 200 different passwords ‘just in case’ doesn’t seem realistic. Is there anything else I can do?
