Tara on "password for admin page"

Hey,
i'm feeling very stupid right now not being able to log in to my admin site anymore. I dindn't use it for a year or more and i have the feeling everything changed!? to login before i used myadress/wp-admin and came to a site where i had to put my name and password now there's just a banner saying i have to give my password and somehow it isn't correct but there's no option to reset it. and i checket my e-mails but cannot find any registration mail from wordpress. what should i do?

In WordPress, there is more than one way for Rsetting Your Password .
