Beginners Questions • [Newb] password unrecognized

Hi all!
Please, apologize me but my Linux knowledge is very poor.
Two months ago I installed Debian 13, create a user/password, installed some packages and all worked fine.
Today I switch on the PC, selected Debian boot then entered the usual password but the password is not recognized.
I never changed the password and the password is correctly entered.

I tried reboot or switch off/on, but the password is not accepted.
What can I do?
