I think in mattermost the solution was to use a password less complicated.

Hello,
I no longer know where I marked it (on the Forum or on Mattermost). But where, the problem is solved by putting a complex password.
It’s good.
One more security.
Thank you for your feedback.
Have a good day.

This question has been solved in the [mattermost channel](https://mm.wazo.community/wazo-platform/pl/fp5nt6cewfrc9g7wu7iz69181o). I (try) copy paste the response
> fblackburn [06:27 AM]
> For wazo-auth-cli the argument is `--auth-username` not `--auth-user`
> fblackburn [06:31 AM]
> But if your curl command doesn’t work, then you have entered a wrong username/password. You can check the username with `wazo-auth-cli user list --recurse` . Otherwise you can create a wazo-auth-cli token with `wazo-auth-cli token create` to update your user password with API
