Solution

The game is a modified version of Not Tetris, made by stabyourself.net (yes, that's a real website, they make awesome games). The first part of the password is found by looking at the rotation of the next piece. If it rotates clockwise, it represents 1, and counterclockwise 0. Concatenating all 1s and 0s and translating from binary, one gets the string "lone". For the second part of the password, one should realize that the Tetris pieces always occur in the same, repeating order. With a little help from google, one can discover that each Tetris piece (also known as tetromino) are associated with a letter (i.e., line piece represents I). The piece pattern spells "soloist" over and over, which is the second part of the answer. Thus, the final password is lone soloist
