The words in the circles are in the runic language from the game TUNIC. They translate to:

TRUMAN      PALMER
WELLES      BRYANT
PENNINGTON  WYATT
COX         GREEN

These are all last names of actors who have played Professor Moriarty.

Their first names are:

RALPH    NOLAN
ORSON    CHARLES
MICHAEL  EUSTACE
ALAN     DENIS

Taking the first letter of each name going down each column gives ROMANCED gives the pastebin. To get the password, connect the dots going from the least recent to most recent adaptation to spell out RICHARD. This is the pastebin password!

Interestingly, there is another actor who played Moriarty called Frederick Valk. This may be the Valk referenced in the password for math? https://en.wikipedia.org/wiki/Frederick_Valk
