Saner TOTP provisioning
A user's e-mail address may be fluid, and the site "instance name" may be strange or change regularly. There's no reason to use these over the user's stable ID and the site's stable hostname for TOTP parameters. Even if the system is built to TOLERATE changes (as it is -- I tested it), it seems much more elegant to have these para- meters as stable identifiers.
