Separate my account from 'sign in with google'

I set up my account using 'Sign in with Google' but I now want to separate my jotform login from my google login. I tried changing my password and although it seemed to accept it it wont let me login using my account name and new password - I still have to then use 'sign in with google'. What do I need to do stop using 'sign in with Google' 

Would it work if I changed my email address to a different one, would this succesfully 'break' my 'sign in with google' connection?

Many thanks. Love the software!

Thank you for your kind feedback! 

As far as I understand, no password is set up if you have signed up with google account. Please use your google email to reset the password. This should allow to set a new password for your JotForm account via the link sent and when set, google sign in should be successfully separated.
