Add token or password

[joaander]

Feature description

Require the use of token or password security by default.

Proposed solution

For example, (by default) jupyter lab creates a random token and displays it on the console.

Additional context

Without authentication, signac-dashboard instances are open to all users on a multi-user system (such as a cluster login node). Malicious users could use this connection to read your signac dashboard, write if any modules enable writing, and possibly take control of your account through vulnerabilities.

This is a good idea and is needed to move the project from being a prototype to a production-level package. I do not have a timeline planned for adding this feature myself, but I would support any contributor who wishes to implement this. Jupyter Notebook's security page may be a helpful reference.
