Frequently logs me out of my account, and have to keep changing my password.

This has been happening for years, but today has been the worst.

Minecraft keeps logging me out randomly, and most of the time I need to change my password.

Because of Minecraft's odd password rules, I have to make a new password each time, with capitols, numbers, symbols etc

I have changed my password at least 20+  times already.

Along with that, which is sometimes linked to the above problem. Minecraft randomly says I can't log into a server, and I need to restart the entire game. Again, has happened for years, but has been really bad for it, today.

This can't be a normal thing. Any help?
