This changeset pulls in all of the notification_utils code directly into the admin and removes it as an external dependency. We are doing this to cut down on operational maintenance of the project and will begin removing parts of it no longer needed for the admin.

This changeset removes webauthn from the Notify.gov admin app. We are not using webauthn at all in our implementation and will be looking at an entirely different authentication system in the near future.

It should be enough to check the user has it set as their auth type.
Even if a user is no longer eligible to register a security key, it
should still be OK for them to continue using the feature.
Previously this was duplicated between the "two_factor" and the
"webauthn" views, and required more test setup. This DRYs up the
check and tests it once, using mocks to simplify the view tests.
As part of DRYing up the check into a util module, I've also moved
the "is_less_than_days_ago" function it uses.
This better reflects how the code is reused in other views and is
not specific to two factor actions. We have a pattern of testing
utility functionality for each view (as opposed to testing the util
+ the view calls the util), so I'm leaving the tests as-is.
both routes are already valid, however, the link from sign-in sends to
the old link. it fetches whichever URL is second in the route decorator
list when you call `url_for`. Swapping the order around keeps the routes
valid but starts pointing users to the new url.
flashes are consumed by the jinja template calling get_flashed_messages
in flash_messages.html.
When you call `abort(403)` the 403 error page is rendered, with the
flashed message on it. However, the webauthn endpoints just return that
page to the ajax `fetch`, which ignores the response and just reloads
the page.
Instead of calling abort, we can just return an empty response body and
the 403 error code, so that the flashed messages stay in the session and
will be rendered when the `GET /two-factor-webauthn` request happens
after the js reloads the page.
if user has `webauthn_auth` as their auth type, then redirect them to an
interstitial that prompts them to click on a button which right now just
logs to the JS console, but in a future commit will open up the webauthn
browser prompt
content is unsurprisingly not final.
Some email clients will pre-fetch links in emails to check whether
they’re safe. This has the unfortunate side effect of claiming the token
that’s in the link.
Long term, we don’t want to let the link be used multiple times, because
this reduces how secure it is (eg someone with access to your browser
history could re-use the link even if you’d signed out).
Instead, this commit adds an extra page which is served when the user
clicks the link from the email. This page includes a form which submits
to the actual URL that uses the token, thereby not claiming the token as
soon as the page is loaded.
For convenience, this page also includes some Javascript which clicks
the link on the user’s behalf. If the user has Javascript turned off
they will see the link and can click it themselves. This is going on the
assumption that whatever the email clients are doing when prefetching
the link doesn’t involve running any Javascript.
This Javascript is inlined so that:
- it is run as fast as possible
- it’s more resilient – even if our assets domain is unreachable or the
connection is interrupted, it will still run
We’re going to add an interstitial page that redirects to this new URL.
But we don’t want that redirect to 404 while the change is deploying,
because some boxes will have the new URL and some won’t. So let’s deploy
the new URL to all the boxes first, then the redirect page can safely
take over the new one.
The new URL is going to be `post` not `get` because that feels more
HTTP-y, so we need to make sure that’s part of this change too.
This page is slow to load which means:
- it’s annoying for us
- it’s potentially causing load on the database
This commit does two things to reduce the amount we’re unnecessarily
looking at this page:
1. Avoid redirecting to it when signing in as a platform admin user
2. Don’t go directly to it when clicking ‘platform admin’ at the top,
but instead show a holding page (there’s a fair chance you’ve clicked
that link in order to go and manage some email branding or find a
user, not wait for stats to load)
The data flow of other bits of our application looks like this:
```
API (returns JSON)
⬇
API client (returns a built in type, usually `dict`)
⬇
Model (returns an instance, eg of type `Service`)
⬇
View (returns HTML)
```
The user API client was architected weirdly, in that it returned a model
directly, like this:
```
API (returns JSON)
⬇
API client (returns a model, of type `User`, `InvitedUser`, etc)
⬇
View (returns HTML)
```
This mixing of different layers of the application is bad because it
makes it hard to write model code that doesn’t have circular
dependencies. As our application gets more complicated we will be
relying more on models to manage this complexity, so we should make it
easy, not hard to write them.
It also means that most of our mocking was of the User model, not just
the underlying JSON. So it would have been easy to introduce subtle bugs
to the user model, because it wasn’t being comprehensively tested. A lot
of the changed lines of code in this commit mean changing the tests to
mock only the JSON, which means that the model layer gets implicitly
tested.
For those reasons this commit changes the user API client to return
JSON, not an instance of `User` or other models.
This commit stops a new email verification link from being sent to a
user if they click on an email link which has expired or which has
already been used. Instead, they will be see an error message with a
link to the sign in page. This stops the situation where someone could
log in indefinitely (without the needing to enter their password) by
trying to use a used / expired email verification link and receiving a
valid link automatically.

if a user signs in again, clear their file upload data from any
aborted journeys from before, so that their cookies don't fill up
also add some temporary logging when the session starts getting full.
show_accounts_or_dashboard has logic about where you should redirect
to. If we let it do this, then that's nicer than duplicating its
logic. We found that it wasn't accounting for orgs in redirects
properly.
Done using isort[1], with the following command:
```
isort -rc ./app ./tests
```
Adds linting to the `run_tests.sh` script to stop badly-sorted imports
getting re-introduced.
Chosen style is ‘Vertical Hanging Indent’ with trailing commas, because
I think it gives the cleanest diffs, eg:
```
from third_party import (
lib1,
lib2,
lib3,
lib4,
)
```

The user has 10 tries at the password, after which the account is locked.
The same is true for the verify code, the user will have 10 tries before the user account is locked.
specifically, the 2FA page when you first create an account is different to the login 2FA page
and also the 2FA page when you change your phone number is different as well
when a user enters their 2FA code, the API will store a random UUID
against them in the database - this code is then stored on the cookie
on the front end.
At the beginning of each authenticated request, we do the following
steps:
* Retrieve the user's cookie, and get the user_id from it
* Request that user's details from the database
* populate current_user with the DB model
* run the login_required decorator, which calls
current_user.is_authenticated
is_authenticated now also checks that the database model matches the
cookie for session_id. The potential states and meanings are as follows:
database | cookie | meaning
----------+--------+---------
None | None | New user, or system just been deployed.
| | Redirect to start page.
----------+--------+---------
'abc' | None | New browser (or cleared cookies). Redirect to
| | start page.
----------+--------+---------
None | 'abc' | Invalid state (cookie is set from user obj, so
| | would only happen if DB is cleared)
----------+--------+---------
'abc' | 'abc' | Same browser. Business as usual
----------+--------+---------
'abc' | 'def' | Different browser in cookie - db has been changed
| | since then. Redirect to start
* all current invocations of get_services now call get_active_services
EXCEPT for platform admin page (where we want to see inactive services
* cleaned up parameter names and unpacking (since *params is unhelpful)
* fixed incorrect kwarg name in conftest
If you’re a platform admin, you should go straight to the platform admin
page when you log in.
The all services page is just a crappier version of the same thing,
without all the stats, etc.
