You are only supposed to be able to hold 1 raid pass at a time, and your first spin of a gym pokestop while you don't have a raid pass will give you one (once per day). So if you have yesterdays raid pass, use it, then spin a gym stop, you'll get another free raid pass. It's still just one per day, and you can only hold one at a time - but that means you can do two free raids in one day, assuming you didn't do any raids, but did get the pass the day before.

More than one raid pass
Hi, this is my first question here but i see gp since august that i start playing.
The question is that someone has get two free raid pass in one day or use two in the same day; yesterday after my first raid i get a second free pass and today i use one and get other free pass and use it as well, but after that dont get other, some say that is for my level (35) but others say that i just can get one free pass at day and dont see anything on the official page, someone has happened this?
Sorry for bad writhing but in not native.
