After a couple of weeks traveling, I've updated my system (which actually is still running aptosid). For the first time ever, I was asked to change passwords for root and user. In fact, my SDDM was stuck when I tried to login, and found out the problem when I tried the TTY. (I needed to change the password.)
Is there a new password policy?
I've asked the same question in the german section. I guess the reason for this behavior ist the change of the password-hash with debian11 from sha-512 to yescrypt
Have a look here (https://www.debian.org/releases/stable/amd64/release-notes/ch-information.de.html#pam-default-password)
But I'm not shure about this
Thanks for the Info! That makes sense.
