The Password Prompt feature is accessed by selecting a player from the main menu and then clicking their banner sprite repeatedly until you're presented with a popup requesting input. Enter any password phrase into the prompt and click OK to have the page reloaded. If the passphrase was valid, new content will be unlocked and added to your game. I've hidden several such passwords on this website so far, but more will be added in the future.
To get you started, go to the prototype's Demo Mode menu (when logged in) and click the little Dr. Light sprite until you see them prompt, then enter the phrase Ability Get : Bubble Bombs Away! into the text field to have the powerful Bubble Bomb ability added to your game! The ability can be very useful in battle and it's a good intro to using the password system, so I hope you'll try it out. :D
Please note that not all passwords work in all modes - some passwords are only available for Demo Mode and some are only available when logged into a save file. Pay close attention to the context in which you find the passwords, as they often give hints to their use!
Let me know if you have any questions, and I look forward to using this new feature for promotions and other fun goodies! I already have a few ideas for new bonus characters and I'm excited to start playing with this new functionality.

Enter the phrase "Ability Get : Cutter of Darkness!" into either player's password prompt and you'll be rewarded with the Shadow Blade ability - one of first dual type abilities added to the game. The ability is Shadow and Cutter type and as such can be used by ANY Copy Core (Mega Man, Proto Man), Shadow Core or Cutter Core (Cut Man, Metal Man) robot!
@megaprotobassman : Certain passwords can only be used in demo mode, and certain passwords can only be used while logged in. It will normally say in the description of the password where it works and where it does not. The Shadow Blade and Bubble Bomb passwords, for example, ONLY work when logged in.
As far how it works, it's explained pretty clearly in the thread's first post. Select your character (so that their sprite appears in the top-left of the screen) and then click that character image a bunch of times until a popup appears. Enter the password phrase into that box and hit "OK". The menu will be reloaded and the password will work if it was done correctly.
