# django-mfa2 A Django app that handles MFA, it supports TOTP, U2F, FIDO2 U2F (Web Authn), Email Tokens , and Trusted Devices ### Pip Stats [](https://badge.fury.io/py/django-mfa2) [](https://pepy.tech/project/django-mfa2) ### Conda Stats [](https://anaconda.org/conda-forge/django-mfa2) [](https://anaconda.org/conda-forge/django-mfa2) [](https://anaconda.org/conda-forge/django-mfa2) Web Authencation API (WebAuthn) is state-of-the art techology that is expected to replace passwords.  For FIDO2, the following are supported * **security keys** (Firefox 60+, Chrome 67+, Edge 18+, Safari 13 on Mac OS, Chrome on Andriod, Safari on iOS 13.3+), * **Windows Hello** (Firefox 67+, Chrome 72+ , Edge) , * **Apple's Touch ID** (Chrome 70+ on Mac OS X ), * **android-safetynet** (Chrome 70+, Firefox 68+) * **NFC devices using PCSC** (Not Tested, but as supported in fido2) In English :), It allows you to verify the user by security keys on PC, Laptops or Mobiles, Windows Hello (Fingerprint, PIN) on Windows 10 Build 1903+ (May 2019 Update) Touch ID on Macbooks (Chrome) and Fingerprint/Face/Iris/PIN on Andriod Phones. Trusted device is a mode for the user to add a device that doesn't support security keys like iOS and andriod without fingerprints or NFC. **Note**: `U2F and FIDO2 can only be served under secure context (https)` Package tested with Django 1.8, Django 2.1 on Python 2.7 and Python 3.5+ but it was not checked with any version in between but open for issues. Depends on * pyotp * python-u2flib-server * ua-parser * user-agents * python-jose * fido2==0.8.1 # Installation 1. using pip `pip install django-mfa2` 2. Using Conda forge `conda config --add channels conda-forge` `conda install django-mfa2` For more info, see the conda-forge repo (https://github.com/conda-forge/django-mfa2-feedstock) Thanks for [swainn](https://github.com/swainn) for adding package to conda-forge # Usage 1. in your settings.py add the application to your installed apps ```python INSTALLED_APPS=( '......', 'mfa', '......') ``` 1. Collect Static Files `python manage.py collectstatic` 1. Add the following settings to your file ```python MFA_UNALLOWED_METHODS=() # Methods that shouldn't be allowed for the user MFA_LOGIN_CALLBACK="" # A function that should be called by username to login the user in session MFA_RECHECK=True # Allow random rechecking of the user MFA_RECHECK_MIN=10 # Minimum interval in seconds MFA_RECHECK_MAX=30 # Maximum in seconds MFA_QUICKLOGIN=True # Allow quick login for returning users by provide only their 2FA MFA_HIDE_DISABLE=('FIDO2',) # Can the user disable his key (Added in 1.2.0). MFA_OWNED_BY_ENTERPRISE = FALSE # Who owns security keys TOKEN_ISSUER_NAME="PROJECT_NAME" #TOTP Issuer name U2F_APPID="https://localhost" #URL For U2F FIDO_SERVER_ID=u"localehost" # Server rp id for FIDO2, it the full domain of your project FIDO_SERVER_NAME=u"PROJECT_NAME" FIDO_LOGIN_URL=BASE_URL ``` **Method Names** * U2F * FIDO2 * TOTP * Trusted_Devices * Email **Notes**: * Starting version 1.1, ~~FIDO_LOGIN_URL~~ isn't required for FIDO2 anymore. * Starting version 1.7.0, Key owners can be specified. 1. Break your login function Usually your login function will check for username and password, log the user in if the username and password are correct and create the user session, to support mfa, this has to change * authenticate the user * if username and password are correct , check if the user has mfa or not * if user has mfa then redirect to mfa page * if user doesn't have mfa then call your function to create the user session ```python def login(request): # this function handles the login form POST user = auth.authenticate(username=username, password=password) if user is not None: # if the user object exist from mfa.helpers import has_mfa res = has_mfa(username = username,request=request) # has_mfa returns false or HttpResponseRedirect if res: return res return log_user_in(request,username=user.username) #log_user_in is a function that handles creatung user session, it should be in the setting file as MFA_CALLBACK ``` 1. Add mfa to urls.py ```python import mfa import mfa.TrustedDevice urls_patterns= [ '...', url(r'^mfa/', include('mfa.urls')), url(r'devices/add$', mfa.TrustedDevice.add,name="mfa_add_new_trusted_device"), # This short link to add new trusted device '....', ] ``` 1. Provide `mfa_auth_base.html` in your templaes with block called 'head' and 'content' The template will be included during the user login. If you will use Email Token method, then you have to provide template named `mfa_email_token_template.html` that will content the format of the email with parameter named `user` and `otp`. 1. To match the look and feel of your project, MFA includes `base.html` but it needs blocks named `head` & `content` to added its content to it. 1. Somewhere in your app, add a link to 'mfa_home' ```<li><a href="{% url 'mfa_home' %}">Security</a> </li>``` For Example, See https://github.com/mkalioby/AutoDeploy/commit/5f1d94b1804e0aa33c79e9e8530ce849d9eb78cc in AutDeploy Project # Going Passwordless To be able to go passwordless for returning users, create a cookie named 'base_username' containing username as shown in snippet below ```python response = render(request, 'Dashboard.html', context)) if request.session.get("mfa",{}).get("verified",False) and getattr(settings,"MFA_QUICKLOGIN",False): if request.session["mfa"]["method"]!="Trusted Device": response.set_cookie("base_username", request.user.username, path="/",max_age = 15*24*60*60) return response ``` Second, update the GET part of your login view ```python if "mfa" in settings.INSTALLED_APPS and getattr(settings,"MFA_QUICKLOGIN",False) and request.COOKIES.get('base_username'): username=request.COOKIES.get('base_username') from mfa.helpers import has_mfa res = has_mfa(username = username,request=request,) if res: return res ## continue and return the form. ``` # Checking MFA on Client Side Sometimes you like to verify that the user is still there so simple you can ask django-mfa2 to check that for you ```html {% include 'mfa_check.html' %} ``` ````js function success_func() { //logic if mfa check succeeds } function fail_func() { //logic if mfa check fails } function some_func() { recheck_mfa(success_func,fail_func,MUST_BE_MFA) //MUST_BE_MFA true or false, if the user must has with MFA } ```` # Contributors * [mahmoodnasr](https://github.com/mahmoodnasr) * [d3cline](https://github.com/d3cline) * [swainn](https://github.com/swainn) * [unramk](https://github.com/unramk) * [willingham](https://github.com/willingham) # Security contact information To report a security vulnerability, please use the [Tidelift security contact](https://tidelift.com/security).
