Add mobile number asking for which password???

Add mobile number asking for which password???

I'm trying to sync my Gmail with Zoho CRM.
It says: 

POP3 Configuration
To configure your email inbox with POP settings, you must have an email account in Zoho Mail. To create an email account in Zoho Mail, please register with your mobile number and follow the onscreen instructions.

Then I get to the screen:



 WHAT PASSWORD IS IT ASKING FOR????

I sign in with my Google suite account so the only password that is applicable to zoho is  the password for my Google suite account. But it just says "invalid password"

 Really wondering if this is worth the effort ...
