Q: When I try to put my user password in terminal it gives me a"sorrry try again" message

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work.

If the problem is still there, try booting into the Safe Mode.  Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the grey Apple icon and a progress bar appear. The boot up is significantly slower than normal.

Step by Step to Fix Your Mac

Caps lock and typos are incompatible with terminal based password entry. So is entering a root password, where an admin account password is expected.

Are you typing sudo command, or su command?

Just your password, and nothing but your password.

The sudo(8) command allows you to run otherwise system privileged applications from within terminal, without having to create a root (su) password. For now, nevermind.

What are you running in the terminal that prompts for your password?

If that's something that's supposed to help you crack commercial applications, such as games, so you can use them without paying, it's probably a trojan. You're lucky that the command you typed makes no sense. But you may be infected anyway, if you installed the thing.
