You likely told pgadmin to remember (store) passwords.
"If you select “Store password”, pgAdmin stores passwords you enter in the ~/.pgpass file under Unix or :file:%APPDATA%postgresqlpgpass.conf under Win32 for later reuse. For details, see pgpass documentation. It will be used for all libpq based tools. If you want the password removed, you can select the server’s properties and uncheck the selection any time."
