This happened a few times throughout the years. I would try to open Minecraft but I am no longer logged in. I try to log in and my password which I know is correct because I wrote it down, is not accepted. I will try to reset my password and most of the time it works and I can play again but sometimes I don't get any E-mails.
It happened twice before. I'll send in a ticket, about a month later I'll get the link to reset my password and it's fine. But I don't want to wait a month to change my password for the 123213th time. Is there any way to fix it quick now?
Edit: Yes, I checked my spam folder. No Mojang email is not blocked.
