Run this to create a new user account on your Matrix server.
You can do it via this Ansible playbook (make sure to edit the <your-username> and <your-password> part below):
ansible-playbook -i inventory/hosts setup.yml --extra-vars='username=<your-username> password=<your-password> admin=<yes|no>' --tags=register-user
or using the command-line after SSH-ing to your server (requires that all services have been started):
/usr/local/bin/matrix-synapse-register-user <your-username> <your-password> <admin access: 0 or 1>
Note: <your-username> is just a plain username (like john), not your full @<username>:<your-domain> identifier.
You can then log in with that user via the riot-web service that this playbook has created for you at a URL like this: https://riot.<domain>/.
If you've just installed Matrix, to finalize the installation process, it's best if you proceed to Configuring service discovery via .well-known
The script /usr/local/bin/matrix-change-user-admin-status may be used to change a user's admin privileges.
- log on to your server with ssh
- execute with the username and 0/1 (0 = non-admin | 1 = admin)
/usr/local/bin/matrix-change-user-admin-status <username> <0/1>
