How do you get the character in the griffindor common room in Harry Potter?

To access the Gryffindor common room in the Harry Potter series, a student needs to provide the correct passWord to the Fat Lady, the portrait guarding the entrance. Once the passWord is given, the portrait swings open to reveal the cozy common room. The passWord changes regularly, so students must stay updated to gain entry. Additionally, only Gryffindor students are allowed access to this exclusive area.
