Posting my steps to allow zap to login to wordpress.
With my setup having plesk and wordpress with the defender plugin I had to do the following to allow login:
Plesk go to tools and settings / Web Application Firewall (ModSecurity) /
Then deactivate wordpress and wpplugin
Click apply and ok
Then in your wordpress dashboard if you have defender sec plugin go to that and disable recapatcha. This is not aloowing login.
Sign in your zapier wordpress and should be good to go.
