Yes, last login date and time is saved in User entity > LastLogin attribute (you can access this from Account entity as well).
Hope this helps!
No you need to create that attribute.
I needed that too in one of my project, I had to download the module : signinmicroflow.
in the microflow of that module, you can when a user is connecting store the LastLogin in antoher attribute (last_logged_previous for example).
In my case, i had to create two attribute, last_logged, and last_logged_previous, I don’t remember why, but it was probably because the last _login attribute was in the user entity, not in the account.
