How Using new created DB

Connect to postgres with

c:\>psql.exe -h localhost -p 5432 postgres "postgres"

And then
postgres=# create database mydb

Then I try to connect to "mydb" with

C:\> psql mydb
After try many password, include postgres password and OS user password
report ** psql: FATAL: password authentication failed for user
"Administrator" **
OR
C:\>psql -h localhost -p 5432 mydb "mydb"
After try many password, include postgres password and OS user password
report ** psql: FATAL: password authentication failed for user "mydb" **

Could someone here help to illustrate how to connect to a newly created
database
