Can't log in - help appreciated

Hi,

Rather embarrassingly, I am stuck in can’t log in scenario I’ve seen others post about. I have no idea how to resolve it. My site is hosted by Google Domains, and I can get into the Domain Admin and the email associated with the Ghost account, but I can’t log into Ghost to actually post on the site. It says the password is wrong and won’t let me reset it. Any ideas?

Website is www.peppertaemint.com

Thanks
