People with dyslexia and dyscalculia find it difficult to transpose
codes which have consecutive, repeated digits[1].
This commits enhances the algorithm for generating codes to not repeat
the previous digit in a code.
This reduces the key space for our codes from 100,000 possibilities to
65,610 possibilities.

Flake8 Bugbear checks for some extra things that aren’t code style
errors, but are likely to introduce bugs or unexpected behaviour. A
good example is having mutable default function arguments, which get
shared between every call to the function and therefore mutating a value
in one place can unexpectedly cause it to change in another.
This commit enables all the extra warnings provided by Flake8 Bugbear,
except for:
- the line length one (because we already lint for that separately)
- B903 Data class should either be immutable or use `__slots__` because
this seems to false-positive on some of our custom exceptions
- B902 Invalid first argument 'cls' used for instance method because
some SQLAlchemy decorators (eg `declared_attr`) make things that
aren’t formally class methods take a class not an instance as their
first argument
It disables:
- _B306: BaseException.message is removed in Python 3_ because I think
our exceptions have a custom structure that means the `.message`
attribute is still present
Matches the work done in other repos:
- https://github.com/alphagov/notifications-admin/pull/3172/files
and update it when users have to use their email to interact with
Notify service.
Initial population:
If user has email_auth, set last_validated_at to logged_in_at.
If user has sms_auth, set it to created_at.
Then:
Update email_access_valdiated_at date when:
- user with email_auth logs in
- new user is created
- user resets password when logged out, meaning we send them an
email with a link they have to click to reset their password.
For a user to be able to be archived, each service that they are a
member of must have at least one other user who is active and who has
the 'manage-settings' permission.
To archive a user we remove them from all their services and
organisations, remove all permissions that they have and change some of
their details:
- email_address will start with '_archived_<date>'
- the current_session_id is changed (to sign them out of their current
session)
- mobile_number is removed (so we also need to switch their auth type to
email_auth)
- password is changed to a random password
- state is changed to 'inactive'
If any of the steps fail, we rollback all changes.
by hitting POST /<user_id>/email-code, we create an email two factor
code to send to the user. That email contains a link with a token that
will sign the user in when opened.
Also some other things:
"email verification" (aka when you first create an account) doesn't
hit the API anymore
refactor 2fa code verification and sending to use jsonschema, and share code between sms and email
Die marshmallow die!
until work is done to stop using PUT /user/{id} on the admin app, this
function also needs to reset failed logins, cos it's used during the
forgotten password flow
in verify_user_password, if succesful we reset the failed_login_count.
now we use failed_login_count for 2FA attempts, we need to make sure we
reset it in other places too, so that people don't get blocked,
especially in the reset-password user journey.
* verify_user_code - if it's succesful, reset the failed_login_count
* update_password - reset failed_login_count because either
* you're logged in and so it's 0 anyway
* you're resetting your password via pword reset link, and the old
count isn't relevant anymore
When the verify code is wrong or expired increment the failed to login count for the user.
When the verify code is successfully used reset the failed login count to 0.
