Dear Yahoo user,
We're following up on a data security issue that we announced last month and that may affect your Yahoo account information. We sent you an email about this issue previously. You can read the contents of that email, which describes the data security issue, at https://yahoo.com/security-notice-content.
We noticed that you have not changed your password or adopted Yahoo Account Key since we sent you our first email about this issue. We strongly recommend that you promptly change your Yahoo password and adopt an alternative means of account verification, as appropriate. For example, please consider using Yahoo Account Key, a simple authentication tool that completely eliminates the need to use a password.
We also encourage you to follow these security recommendations:
Change your password as well as your security questions and answers for any other accounts on which you used the same or similar information as for your Yahoo account.
Review your accounts for suspicious activity.
Be cautious if you receive any unsolicited communications that ask for your personal information or refer you to a web page asking for personal information.
Avoid clicking on links or downloading attachments from suspicious emails.
For more information about this issue and our security resources, please visit the Yahoo Account Security Issue FAQs page at https://uk.yahoo.com/security-update.
Protecting your information is important to us and we are constantly striving to strengthen our defences against the threats targeting our industry.
Chief Information Security Officer
