I have found that if pgadmin cant reach the postgresql backend, it reports a failed password error instead of a failed connection. You might make sure you back end is up and reachable.
pgAdmin will report whatever the libpq client libraries reports. In this case, perhaps the username "Postgres" is the problem (the correct spelling of the default username being "postgres").

Hi PG I am very new at this. So I was quite baffled when as soon as I tried to access the server, I got “Fatal: password authentication failed for user “Postgres”
The password I used was impossible to get wrong. Its three letters.
