Launcher Logs Me Out

Hello, I have been getting this issue for a long time now. At first I thought that maybe this issue was only isolated to my computer alone, but I got logged out on another computer of mine too. I am not creating this because of that, but because I get logged out of the launcher at least 5+ times a day. I have a very long password and it is somewhat annoying having to type in the password every time this happens. I have checked the "remember me" box and I still get logged out. Additionally, I get "Login failed. invalid username or password" whenever I try to login. That just makes trying to login just that much more frustrating. I have even resorted to typing the exact password somewhere else, copying it, and pasting it into the launcher. I have even changed my password several times and copied the password into the 2 fields, then tried to login with the same exact clipboard password I just used to change it and the website still tells me it is incorrect as well as the launcher. I am unsure what the problem is at this point because I have tried making the .minecraft folder not read only, restarting the launcher, updating to the latest version of Java and even rebooting my modem and the problem always comes back.
