Why app for iMac not asking for google login?

I signed up for jot form online, I chose to sign up with my google account. I downloaded the Jotform app to my computer and it is asking me to sign in using my username and password. I found my username online in settings, but my "password" says incorrect. when I try to reset it, it also says incorrect. Imassuming this is because I never actually set a password, seeing as how I chose to sign up with my google account How can I fix this?

Please try resetting your password again using chrome browser so that you can create a separate password for your account.
