Turning on 2-factor authentication for Trello, I was given the option to copy the recovery codes to the clipboard. I did this (which moved me on to Trello itself) but when I then copied the recovery codes i found they were in just one long string(no spaces). I can't remember if they were 3, 4 or maybe 5 letter blocks.

Using Chrome on windows 10

ps. sorry if OAuth 2.0 is the wrong 'Project type. (couldn't see Trello in the list)
