 ### Preventing reuse of Time based OTP's
 
 By keeping track of the last time a user's OTP was verified, we can prevent token reuse during
 the interval window (default 30 seconds)
 
 The following is an example of this in action:
 
 ```ruby
-User.find(someUserID)
+user = User.find(someUserID)
 totp = ROTP::TOTP.new(user.otp_secret)
 totp.now # => "492039"
 
 # Let's take a look at the last time the user authenticated with an OTP
 user.last_otp_at # => 1432703530
