Password doesn't work sometimes.

Hello. I have noticed, that my password sometimes doesn't want to work. It has been happening for a few days already. I checked the mail everytime and there was a message about password change request. Always after this i have changed the password (everytime it was different). Today i also changed the mail password. About 10 minutes ago i wanted to log in to the launcher. I have wrote the password few times correctly, but it didn't wan't to work. I checked the mail, but there wasn't any password change request. What do i do now?
