Her name is my passwords, fuck
Password is something you don’t share hence Tyler wants to hide her name from others to keep her for himself, showing how much he likes her / is obsessed with her
Taking it further, considering that this is one of the most honest, heartfelt tracks on his Goblin album (lacking all the rape/murder fantasy he’s known for), it could be said that she is the “password” to the more sensitive parts of himself that he normally keeps hidden. He normally keeps up a front, but at the mention of her name, he’s exposed.
And of course there’s the basic meaning — he uses her name for his password for his Facebook profile, email account, etc., because he loves her.
