Security Steps We Have Taken
- Secure Socket Layer (SSL): Yahoo! uses SSL (Secure Socket Layer) encryption when transmitting certain kinds of information, such as financial services information or payment information. An icon resembling a padlock is displayed on the bottom of most browsers window during SSL transactions that involve credit cards and other forms of payment. Any time Yahoo! asks you for a credit card number on Yahoo! for payment or for verification purposes, it will be SSL encrypted. The information you provide will be stored securely on our servers. Once you choose to store or enter your credit card number on Yahoo!, it will not be displayed back to you in its entirety when you retrieve or edit it in the future. Instead of the entire number, you will only see asterisks and either the first four digits or the last four digits of your number.
- Security Key: The Yahoo! Security Key is an additional optional layer of security to control access to sensitive information or services on Yahoo!. Users of financial services such as Yahoo! Wallet, Yahoo! Bill Pay, and Yahoo! Merchant Solutions are asked to create a security key during the sign-up process or when you purchase certain services that require a Yahoo! Wallet. Please note that the Security Key automatically "times out" after an hour and requires the user to sign in again to access Security Key protected areas.
- Secure Storage: Yahoo! maintains reasonable physical, electronic, and procedural safeguards that comply with federal regulations to protect personal information about you.
- Vendors and Partners: Yahoo! works with vendors and partners to protect the security and privacy of user information.
- Employee and Contractor Access to Information: Yahoo! limits access to personal information about you to those employees who we reasonably believe need to come into contact with that information to provide products or services to you or in order to do their jobs.
- Education and Training for Employees: Yahoo! has implemented a company-wide education and training program about security that is required of every Yahoo! employee.
