What is a Yahoo sign in seal? Is it imperative to create one for my account? If so, can I use my photo as the seal?

Yahoo sign in seal is a security measure that can prevent a phishing attack (more on this below). But that’s not the only reason why you should have one. Using your photo or your company logo will personalize the Yahoo login page. Let me elaborate on these two points.
Yahoo sign in seal to prevent phishing
Phishing (pronounced just like “fishing”) is the process employed by swindlers to trick you into revealing personal or sensitive information such as login details. A phishing attack involves an email which acts as a bait and a fraudulent web site that is disguised to look like the original.
In case of Yahoo, the fraudsters would send out millions of emails which typically have a disturbing message such as “Your account has been compromised”, “You need to verify your account else it will be closed down” etc. These emails that are made to look like originating from the Yahoo support department also carry one or more cloaked web links (URLs) that point to the phishing web site – a fraudulent web site which is made to look like the actual Yahoo! login page. Phishers hope that distressed recipients would click on these links and reveal the login information (username and password) on the fake web site thus compromising their accounts and personal information.
People regularly fall prey to such attacks and that is why the tricksters keep on at it.
Creating a Yahoo sign in seal will ensure that even if you do click a web link from a phishing email, you will quickly realize that the web site you’re taken to is not the original because it would be missing this seal.
Personalize the Yahoo login page with the sign in seal
Using the sign in seal feature you can give a nice personalized touch to the Yahoo sign in page. The sign in seals can be text or have an image. Putting your own photograph or uploading the company logo will customize the web page. Check the sign in seal I created with my photograph and personalize the Yahoo login page.

Some important points to remember:
- The Yahoo sign in seal will only work in the web browser that was used to create it. Thus, if you have multiple web browsers installed on your computer, you might think of creating the Yahoo sign in seal on all. Learn how to download and install a web browser on your computer.
- The sign in seal can be simple text or have images – photographs or company logos.
- The text seal consists of up to 21 characters.
- For image based Yahoo sign in seals, the graphic needs to be more than 64 pixels in width and height – very small icons and images will not do!
- If you delete the web browser cache, the Yahoo sign in seal will be removed.
And lastly. NO! it is not necessary to have a Yahoo sign in seal to use the email account. It is just a security measure to protect users against phishing attacks.

My security seal color seems to be a darker pink that what I chose (lavender).
Does this mean that someone has compromised my acct?
No. The color does change a little when it’s finally applied to the sign in seal on the login page.
I’ve put my photo as the Yahoo sign in seal. This is great! I love the Yahoo service.
