Securing My Account?

Question

I don't want any outsider able to access my account. For example I don't want them to have the ability to use my i.d. which is [e-mail]

Answer 1

Step 1: Don't post information on a public forum that you don't want accessed by the public.
Step 2: Don't give out your password.
Step 3: Use the 'Help' link at the bottom of any Yahoo page to find the correct place to address your question.

BTW, this question has nothing to do with credit.
