A Log-in Seal is a unique text that you select to help protect your account from phishing websites. Phishing (fraudulent) websites imitate legitimate websites. These websites are designed to steal your password and your personal information. After creating a Text Log-in Seal for your computer, you can make sure you're on the legitimate tc-v.com site each time you log in to TCV. Simply check whether the customized text is displayed on the tc-v.com webpage. If you do not see it, you may have accessed a fake TCV site.
