Password Protected Heart

I built these walls with careful code
Each scar became a firewall
You'll never guess the words I chose
The password to my bleeding soul

Eight characters
One special sign
A fortress made
Of fear and time

Password protected heart
You'll never break the code
Password protected heart
I carry mine alone
No brute force can decrypt
What I chose to hide
Password protected heart
Forever locked inside

I changed the keys a thousand times
Each lover got a different door
But all the paths led to the same
Empty room I can't explore

Two-factor fear
Biometric tears
I authenticate
My deepest fears

But who protects the protector?
Who guards the guard?
I'm locked inside my own defense
A prisoner of my own art
