Locked out of my Wordpress dashboard out of nowhere


For quite awhile I have had the same user name and password for my T-shirt website Wordpress dashboard. When I switched to cloudflare after a few months I’m currently locked out of my dashboard. Weird because I didn’t change anything and I saved the user name and password to my laptop for easy login and I can’t get into it. I’ve tried resetting the password with no luck and can’t figure it out. Any help would be greatly appreciated.
