I've received an email that says:
Looking after your security is always important to us at Quidco. Next time you try to access your Quidco account you will need to reset your password.
We’re asking you to do this because we’ve detected suspicious activity, which suggests your Quidco account may have been accessed by someone who isn’t you. This can happen if you use the same password across more than one website and one of those websites has been compromised.
I just tried to log in and it wouldn't recognize my log in.
