- Updated auth system for mfa to not update intended URL so that the
user is not redirected to mfa setup after eventual login.
- Added notification for users setting up MFA, after setup when
redirected back to login screen to advise that MFA setup was complete
but they need to login again.
- Updated some bits of wording to display better.
- Restructured some of the route naming to be a little more consistent.
- Moved the routes about to be more logically in one place.
- Created a new middleware to handle the auth of people that should be
allowed access to mfa setup routes, since these could be used by
existing logged in users or by people needing to setup MFA on access.
- Added testing to cover MFA setup required flow.
- Added TTL and method tracking to session last-login tracking system.
Also added testing to cover as part of this in addition to adding the
core backup code handling required.
Also added the standardised translations for switching mfa mode and
adding testing for this switching.
