Updating users passwords

If you are using the matrix-postgres container(default), 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>' --tags=update-user-password

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 are NOT using the matrix-postgres container, you can generate the password hash by using the command-line after SSH-ing to your server (requires that all services have been started):

docker exec -it matrix-synapse /usr/local/bin/hash_password -c /data/homeserver.yaml

and then connecting to the postgres server and executing:

UPDATE users SET password_hash = '<password-hash>' WHERE name = '@someone:server.com'

where <password-hash> is the hash returned by the docker command above.
