'Not able to connect to psql (only superuser) in terminal and im thinking this is causing the code I am trying to output to get an error

I am getting this message when I try to enter "psql" in the terminal.
So far I have manually removed an "encrypted" password and replaced it to "password" in pgAdmin4 sql entry for users.
here is the code and the error it calls back:
postgres-# \q
➜ ~ psql
Password for user ao:
psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed:
FATAL: password authentication failed for user "ao"
