New launcher not accepting password

I was normally starting up minecraft, and the first time around was fine. I opened the game and played on Realms for a while. After that, a message came up about my "host machine". I tried to join back but got the Invalid Session message. So as I would normally, I closed the game hoping to start it up again. When I started up the launcher however, I was greeted with an image of a creeper and a message about my connection. I went to check my wifi but all of it was working perfectly normal everywhere else on my laptop and other devices. I closed the launcher and started it up once more. This time it asked me to log in which I thought was rather strange as it never does. I carried on, entering my password and email which I was 100% sure was correct. It kept saying my password was incorrect. I went to reset it with the email and after opening the link, it said: Error! with a message stating something about an invalid try. I proceeded to attempt reset a few more times. Each time it did not work. Going back to try the password, it still wouldn't work.
