Do I need to go change my password now?  

Create a strong password for your Apple ID, It is best if your password consists of eight or more characters and include upper and lowercase letters, and at least one number. You can also add extra characters and punctuation marks to make your password even stronger. 

Never provide your password, passcode, security questions, verification codes, recovery key or any other account security details to anyone else. Apple will never ask you for this information.

Someone may be trying to sign your Apple ID, which would generate the request for a verification code. Since you have 2 Factor Authentication enabled, as long as they can't access one of your trusted devices, they can't get a code, and sign in. You should be okay.

Second time got two factor authenticity request for resetting password for Apple ID. This isn’t me I have looked around in settings and account. Checked purchases and nothing appears to be changed or any odd activity. Just the texts and emails to say here is your access code if you did try to reset.
