I’m having trouble resetting my password – Google Account Help

Someone might have hijacked your account and added it. If you still have access to one of the options, try using it to reset your password. Once you’re back in your account, check all your account details, delete any information you don’t recognize, and walk through the Security Checkup to help secure your account and computer.
