+ # Currently I have a user to be signed in forever unless they

+ # If you want to change that, change line 7 to this:
+ #
+ # cookies[:remember_token] = { value: remember_token,
+ # expires: 20.years.from_now.utc }
+ #
+ # which will expire the cookie in 20 years from its date of
+ # creation.
+ #
+ # Oddly enough, this line above is equivalent to the:
+ #
+ # cookies.permanent
+ #
+ # This is just a short cut for this line since most people
+ # create permanent cookies these days.
+ #
+ # Other times are:
+ #
+ # 10.weeks.from_now
+ #
+ # 5.days.ago
+ #
+ # etc...
