Account security is something you get much more serious about after a close call like this. Being able to reset password like on other services had lulled me into a false sense of security. I was lucky that I could contact people through HiveChat.
I will be updating this post soon because I have resolved my error issues. Turns out it was either Brave browser of the Keychain plugin there. I tried using Firefox and everything is OK there.
