+Feature: Prevent brute force attacks
+  Background:
+    Given users are blocked for 5 minutes after 2 failed login attempts
+    And there is a user named "bob"
+
+  Scenario: A user failing to login on the first time can login on second attempt
+    When I try to log in with user "bob" and a wrong password
+    Then I should not see "Bob Bobbit"
+    When I try to log in with user "bob"
+    Then I should see "Bob Bobbit"
+
+  Scenario: A user can't login after two failed attempts, but can after waiting 5 minutes
+    When I try to log in with user "bob" and a wrong password
+    Then I should not see "Bob Bobbit"
+    When I try to log in with user "bob" and a wrong password
+    Then I should not see "Bob Bobbit"
+    When I try to log in with user "bob"
+    Then I should not see "Bob Bobbit"
+    When the time is 6 minutes later
+    And I try to log in with user "bob"
+    Then I should see "Bob Bobbit"
