How to use payment link without client having to log in?

Is it at all possible to use the Payment Links without the customer having to log in? I am thinking about connecting a payment link to a QR code for an event. However, whenever testing it keeps asking for a password to the client portal even when the client portal is not activated.

Is there anyway to go straight to the credit card payment screen?

Thank you!


Is the password feature enabled on Settings > Client Portal > Authorization?
