# Updating users passwords ## Option 1 Use the Synapse User Admin API as described here: https://github.com/matrix-org/synapse/blob/master/docs/admin_api/user_admin_api.rst#reset-password This requires an access token from a server admin account. If you didn't make your account a server admin when you created it, you can use the `/usr/local/bin/matrix-make-user-admin` script as described in [registering-users.md](registering-users.md). ## Option 2 (if you are using the default matrix-postgres container): You can reset a user's password via the Ansible playbook (make sure to edit the `` and `` part below): ansible-playbook -i inventory/hosts setup.yml --extra-vars='username= password=' --tags=update-user-password **Note**: `` is just a plain username (like `john`), not your full `@:` 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./`. ## Option 3 (if you are using an external Postgres server): You can manually generate the password hash by using the command-line after **SSH**-ing to your server (requires that [all services have been started](installing.md#starting-the-services)): 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 = '' WHERE name = '@someone:server.com' where `` is the hash returned by the docker command above.
