Can't login on Account

Hi I am actually new to WordPress. I only started using WordPress last March, 2015. I am not that well versed in web management. I don’t have a WordPress downloaded in my iMac and I only use the browser version to update the content of our company’s site.

To start off, our company website https://www.lightroom.ph is using the Goodwork theme. I last logged in the site lightroom.ph on May 1, 2015. I updated the content and published the updates afterwards. Today, when I tried to log in, I can’t get through. The page prompts ERROR: The password you entered for the username admin is incorrect. Lost your password? This is strange because I didn’t change the password for the account. I search online for trouble shooting. I cleared the cache, used another browser to login, I tried loggin in from another internet connection and I stil can’t login.

Here’s the worse part. This site was actually made by a third party contractor. Besauce they failed to update the content of the site, I was given teh task to manage the content of the site. I can’t access the emails that the previious company who made the site because it seems that the emails were made using another email domain and not out company’s email domain. Now, I tried to contact the previous company who made the site for them to assist us in utilizing the Lost your password option. Unfortunately they have not responded yet and the person who made the site is no longer with the company.

What I want to know if is that is there a work around for this if in case the company that I am trying to contat could not help me to regain aaccess to the account?
