[Intro: Haewon, Jiwoo]
Da, da-da-da (Yeah), da-da-da, da-da-da
What's your password? (Ooh-woah, yeah)
Da-da-da, da-da-da (Yeah), da-da-da
(Oh-oh-ooh-woah)

[Verse 1: Jiwoo, Bae]
Alright, first things first, system check
I'll do some stretching before I start
Stay on your toes, there's not many chances
(Da-da-da, eenie, meenie, miney, moe)
Oh, why is it not as easy as I thought? (Stop)
Your birthday, and even your number
Are spreading blue inside my head

[Pre-Chorus: Sullyoon, Jiwoo, Lily & Kyujin, Lily, *Haewon*]
An uncountable number
Is the amount of scenarios
Thousands and millions, the odds are 1%
I'm getting more curious
Try, that's right
Let's try one letter at a time
Collect all the data, mix it around
*Like du-du-du-du-du*

[Chorus: Haewon, Lily, Kyujin]
What's your password? There is only one
Right now, I'm logging into you
(Password, password) I know you want it too
What's your password? I want to know
The code to connect myself with you
(Password, password) Type it, type it
The one and only password

[Post-Chorus: Haewon, Jiwoo]
Du-du-du-du-du, du-du-du-du-du
Da-da-da, what's your password?
Du-du-du-du-du, du-du-du-du-du
The one and only password
Da, da-da-da (Oh-oh-ooh-woah)

[Verse 2: Haewon, Bae, Jiwoo]
You are so tricky, like a quiz in an endless maze
At this point, do a system check one more time
(Da, da-da, da-da, da-da, overload)
Oh, why is this screen-blocking error so frustrating?
Nah-ah, it's a wrong password (No, no, no, no)
Tap, tap, don't stop and keep typing

[Pre-Chorus: Sullyoon, Jiwoo, Bae & Kyujin, Bae]
An uncountable number
Is the amount of scenarios
Thousands and millions, the odds are 1%
I'm getting more curious
Try, that's right
Let's try one letter at a time
Collect all the data, mix it around
Like du-du-du-du-du

[Chorus: Sullyoon, Lily, Jiwoo]
What's your password? There is only one
Right now, I'm logging into you
(Password, password) I know you want it too
What's your password? I want to know
The code to connect myself with you
(Password, password) Type it, type it
The one and only password

[Bridge: Kyujin, Sullyoon, Jiwoo]
I'm now in hacker mode, connecting with you
Blow everything away, system, system
I'm at the final stage, we are a special case
Just wait for it, loading, loading
A to Z, tell me what you like the most
Collect all the data, mix it around
Like du-du-du-du-du

[Chorus: Jiwoo, Sullyoon, Kyujin, Lily]
What's your password? There is only one (Oh)
Right now, I'm logging into you (You, yeah)
(Password, password) I know you want it too
What's your password? I want to know (Word)
The code to connect myself with you
(Password, password) Type it, type it
The one and only password

[Post-Chorus: Haewon]
Du-du-du-du-du, du-du-du-du-du
Da-da-da, what's your password?
Du-du-du-du-du, du-du-du-du-du
The one and only password
Da, da-da-da
