Add register link to the login form during checkout

Hi,

I want to add a link for registration to the login form during checkout. I want the customer to register and verify their email/mobile before purchasing, so I want them to force registration during checkout. Currently, only the login option is there.

Also, if a customer added their items to the cart and registered their account, after email verification (on the same browser only) then he should be able to checkout with his cart items. This is already available when the customer logs in during checkout, I want the same thing to happen when he registers also.

Please find the attachment for your reference.

Thank you,
