What to do if someone attempted to sign in to my account

[CDKristopherP · Accepted solution]

If you know or feel that your account is vulnerable, there are a couple of options.  Either way you would want to sign in to your account.  Go to My Account > Account Settings.  You can then go into the SECURITY tab and create a new password or pass phrase, and you can also turn on two-step verification where you would receive a text message with a verification code to access your account.  Both of these options will increase you account security, especially the two step verification.
