Add Two Factor Authentication #842

TillerBurr · 2019-05-20T16:50:51Z

Rebased #773 and #522
This PR solves: #496

Much of the CI Failures were due to formatting issues. Also contains the following:

Updated release.py to accommodate Python 3 versions (prevented CI tests from passing.)
Added Python 3.7 to the CI tests
Updated requirements due to a conflict in Werkzeug and Flask. (See Unable to send POST request using Flask test client pallets/flask#3148)

* supporting two factor authentication: * Support Mail, SMS, or Google Authenticator second factor authentication. * Ability to change second factor authentication to existing users * Provide rescue mail in case of lost phone * update docs with two factor authentication changes * updating requirements, authors * adding two_factor test * improving tests coverage

request.json->request.get_json update tests to use hash_password pep8 compliance Update dependencies for tests move from pyenchant to msgcheck

Thanks for this awesome PR.

Do you consider making this pull to the Flask-Security-Too fork at https://github.com/jwag956/flask-security?

The fork is more active. See #822.

Just some minor spelling errors.

There is also a mix between 'two factor' and 'two-factor'.

Thanks. I didn't change much on the docs, mostly just to make sure that the CI tests pass. I've made some changes to the codebase.

The main reason that I did not make a pull request to https://github.com/jwag956/flask-security was that in #822 @lnielsen was added as an admin/maintainter on the various sites. I can definitely make a pull request to Flask-Security-Too.

jwag956 · 2019-05-28T16:58:26Z

I would be happy to help get your change into flask-security-too. I have been trying to work with current flask-security maintainers but so far to no avail - so I have decided at least for now to go off and formalize my fork.
I am working on a 3.2.0 release that will contain a few feature improvements - in particular support for Single-Page-Applications (more complete json support) as well as documentation improvements, and a contributed authentication token cache.
Adding 2-factor to 3.2.0 should be doable and I hope to get that release out in the next couple weeks.

Please be aware that on my fork - I need PRs against MASTER (not develop). Hopefully most of non-feature related code changes won't be necessary.

I have a rc1 for 3.2.0 on pypi:

https://pypi.org/project/Flask-Security-Too/#history

which currently is based off of master branch.

One thing I am not completely sure about is how/what needs to be done to update translations - obviously you cant do all languages - but I think you need to update flask_security.pot at least with your new messages.

jwag956 · 2019-05-28T17:02:02Z

flask_security/twofactor.py

+
+
+def generate_totp():
+    return base64.b32encode(os.urandom(10)).decode('utf-8')


I don't think this should be in code - different applications will have different requirements here. For example in 3.6 there is now a secrets module that is probably better...

All I did was rebase the old pull requests to get them working and passing the CI tests. I can work on this at some point, but not sure when I will be able to get to them.

jwag956 · 2019-05-28T17:02:56Z

flask_security/twofactor.py

+    """generate the qrcode for the two-factor authentication process"""
+    if 'google_authenticator' not in\
+            config_value('TWO_FACTOR_ENABLED_METHODS'):
+        return abort(404)


In general I think that utility functions like this should NOT be assuming a request context - rather throw an exception to the caller?

jwag956 · 2019-05-28T17:04:05Z

flask_security/twofactor.py

+        pass
+
+
+def get_totp_uri(username, totp_secret):


Question - did you consider using passlib.totp classes rather than rolling your own?

jwag956 · 2019-05-28T17:05:39Z

flask_security/views.py

+        # if user's two-factor properties are not configured
+        if user.two_factor_primary_method is None or user.totp_secret is None:
+            session['has_two_factor'] = False
+            return redirect(url_for('two_factor_setup_function'))


This isn't JSON friendly!

I thought I had changed that back. I'm reverting it

TillerBurr · 2019-05-28T21:05:43Z

Thank you for your help. This is not my initial code and I am kind of jumping into it without understanding what the original author was trying to do.

jwag956 · 2019-05-28T22:40:01Z

Let me know when you believe you are done - and I will cherry-pick that over to my fork. It will be a bit of a mess due to all the non-2FA changes - but shouldn't be too hard.
I assume you have an app that actually uses this so you can test that it actually works?

TillerBurr · 2019-05-29T21:00:46Z

@jwag956 I've got it passing all of the CI tests and I've tested it in an app that isn't a SPA. The force push from earlier was just to squash a bunch of smaller commits that I was working through with the CI.

I was trying to locally merge your fork with my current branch, but at this point there is too much of a difference to try to merge without stepping on your toes. If this gets merged into your fork, I will try to keep an eye on it. There is much that can be improved on the backend, e.g. hashing the totp_secret, not storing it on the user model etc. but I think this is a good start.

jwag956 · 2019-05-30T01:41:02Z

That was painful - doing a rebase rather than cherry-pick - in any case - I have a PR up - made minor changes, and had to fix some doc stuff since my CI actually verifies that the docs build!

In my PR I added a bunch of questions that I could use your help on. I am mostly concerned about things that if we change later would not be backwards compatible.

Also - please look at:
https://coveralls.io/builds/23685029

looks like we need some more unit tests!

TillerBurr · 2019-05-30T14:10:39Z

I can do this on your fork as well. As far as syntax checking, I am currently using vscode and it sometimes throws a bunch of unresolved imports that aren't true. I try to catch them, but apparently I seem to enjoy missing them.

jwag956 · 2019-05-31T07:48:05Z

Thanks - that would be great. I use Pycharm and it also sometimes makes mistakes - but if you run the code - doesn't it work/throw an error? I guess I am just asking why commit/push just to check if it runs? I both run from PyCharm - but also, to check pep8 etc - I run python setup.py test before committing... let me know if you run into any issues on my fork. Just work on the same branch (baurt) - I think it will let you - I just added you as a collaborator.

Luckily. i read the pull requests and found this comment. Else i will be stuck on old. :D

Although OWASP still recommends that reset password and confirmation links have the no-referrer header option set - this causes issues with HTTPS and Flask-WTF that requires a referrer header. Also - for the past 5 years, the browser default for Referrer-Policy is 'strict-origin-when-cross-origin' which should be enough to mitigate any possible Referrer leakage. closes pallets-eco#829
