Cannot log into my new Mac mini

I migrated information from my old Mac mini to my new Mac mini. The system told me that my husband‘s account would have to have a new password before we could login with that account. It is not the administrator account. It is a secondary account on the computer. I have the password that it gave me and have entered it. It brings me to the reset password screen. I typed in a new password verified it, and gave it a hint, and it still will not allow me to reset the password so that I can log into the new Mac mini.
