If my girlfriend but me a ticket online and I font have an id. Will the bus driver still allow me on the bus if I have the password and confirmation number?

The driver does not look at the id card. All they want is the bus ticket. ID maybe needed to get your ticket from the counter unless you print it from home.

They need an ID to pick up the ticket

Yes they will give her a special number and you must present that number to them

They will required an I'd because is an online ticket thts the policy of the company of course we have some lazy drivers that don't ask for it but most of drivers for sure they do it I recommend you to get an e-ticket so you won't need not id

I appreciate your response. Thank You

I been on the greyhound bus
