Can't login using the correct password/email

When I tried to log in using my account in Minecraft launcher it is saying it is an invalid or wrong password. I tried using the same password and email on my friend's computer and it worked. I tried logging in to minecraft.net but after I click the login button it doesn't do anything. It doesn't even show me if the password is wrong or right, it stays on the same page.

I don't understand what is wrong with my computer or the game, please help me!!!.
