Well I would say the Postgres server has pg_hba.conf setup to require
password authentication for host(ssl) connections. A good idea.
You need to back to part above where you shelled into psql prompt and
use ALTER ROLE:
https://www.postgresql.org/docs/12/sql-alterrole.html
and do
ALTER ROLE firstname.lastname WITH LOGIN PASSWORD 'the_password';
You need the LOGIN if you want that role to connect directly to database.
FYI, the above can be done as part of CREATE ROLE also:
https://www.postgresql.org/docs/12/sql-createrole.html
You probably want to read through above anyway to see what the options
are and they do.
