Problème de connexion à MySQL avec MAMP

Quand je lance cette commande, ça semble lancer Oracle, et aucun mot de passe ne m'est demandé, voilà ce que ça affiche:

../../Applications/MAMP/Library/bin/mysqladmin Ver 8.42 Distrib 5.6.38, for osx10.9 on x86_64

Administration program for the mysqld daemon.
Usage: ../../Applications/MAMP/Library/bin/mysqladmin [OPTIONS] command command....
--bind-address=name IP address to bind to.
-c, --count=# Number of iterations to make. This works with -i
(--sleep) only.
--debug-check Check memory and open file usage at exit.
--debug-info Print some debug info at exit.
-f, --force Don't ask for confirmation on drop database; with
multiple commands, continue even if an error occurs.
-C, --compress Use compression in server/client protocol.
--character-sets-dir=name
Directory for character set files.
--default-character-set=name
Set the default character set.
-?, --help Display this help and exit.
-h, --host=name Connect to host.
-b, --no-beep Turn off beep on error.
-p, --password[=name]
Password to use when connecting to server. If password is
not given it's asked from the tty.
-P, --port=# Port number to use for connection or 0 for default to, in
order of preference, my.cnf, $MYSQL_TCP_PORT,
/etc/services, built-in default (3306).
--protocol=name The protocol to use for connection (tcp, socket, pipe,
memory).
-r, --relative Show difference between current and previous values when
used with -i. Currently only works with extended-status.
--secure-auth Refuse client connecting to server if it uses old
(pre-4.1.1) protocol.
(Defaults to on; use --skip-secure-auth to disable.)
-s, --silent Silently exit if one can't connect to server.
-S, --socket=name The socket file to use for connection.
-i, --sleep=# Execute commands repeatedly with a sleep between.
--ssl Enable SSL for connection (automatically enabled with
other flags).
--ssl-ca=name CA file in PEM format (check OpenSSL docs, implies
--ssl).

--ssl-cert=name X509 cert in PEM format (implies --ssl).
--ssl-cipher=name SSL cipher to use (implies --ssl).
--ssl-key=name X509 key in PEM format (implies --ssl).
--ssl-crl=name Certificate revocation list (implies --ssl).
--ssl-crlpath=name Certificate revocation list path (implies --ssl).
--ssl-verify-server-cert
Verify server's "Common Name" in its cert against
hostname used when connecting. This option is disabled by
default.
--ssl-mode=name SSL connection mode.
-u, --user=name User for login if not current user.
-v, --verbose Write more information.
-V, --version Output version information and exit.
-E, --vertical Print output vertically. Is similar to --relative, but
prints output vertically.
-w, --wait[=#] Wait and retry if connection is down.
--connect-timeout=#
--shutdown-timeout=#
--plugin-dir=name Directory for client-side plugins.
--default-auth=name Default authentication client-side plugin to use.

J'ai essayé avec cette commande
../../Applications/MAMP/Library/bin/mysqladmin -u root -p root, et il me demande un mot de passe avec ça, je tape donc root et il me répond:

Enter password:
../../Applications/MAMP/Library/bin/mysqladmin: Unknown command: 'root'

Ok, enlève le -p de la commande, comme suit :

/Applications/MAMP/Library/bin/mysqladmin -u root

Je l'ai fait mais ça ne change rien, il me crache toujours sa suite de commandes existantes :(

Peux-tu faire une capture d'écran de ton utilisation de la commande ? La sortie n'est pas normale, c'est comme si il ignorait les paramètres.

Elle ne trouve pas la commande car ton terminal ne connaît pas l'emplacement de MySQL. Par contre, tu dis pouvoir executer la commande via phpMyAdmin, tu as donc dû te connecter. As-tu utilisé les mêmes identifiants ou as-tu été connecté automatiquement ?

Non j'ai été connecté automatiquement, en lançant MAMP il m'envoie sur sa page, de là je vais sur
Tools->phpMyAdmin et je suis connecté directement. Mais lorsque je lance MAMP, j'ai ces indications sur MySQL:
