Are you saying you save logged into it with your Apple ID, but forgot the password?

Troubleshooting a Locked iPhone:

What to Do:

Is this is a used device? If so, the person currently signed in to the iPhone needs to log themselves out of it. Elsewise, it is useless to your account. Have the Seller go here: What to do before you sell, give away, or trade in your iPhone, iPad, or iPod touch - Apple Support. The seller should have known better.

Thank you for the photo.

Return it. Seems you've been scammed. So, take this as a learning experience, knowing to attempt an iCloud login prior to handing over the money. If the seller decides to disabide by the rules you've set forth, then do no proceed with the transaction.
