 # 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
+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.

+
+if "mfa" in settings.INSTALLED_APPS and getattr(settings, "MFA_QUICKLOGIN", False) and request.COOKIES.get('base_username'):

+    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' %}
+{% include 'mfa_check.html' %}
 ```
 ````js
 function success_func() {
-  //logic if mfa check succeeds
+  // logic if mfa check succeeds
 }
 function fail_func() {
-  //logic if mfa check fails
+  // 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
-  }
+  recheck_mfa(success_func, fail_func, MUST_BE_MFA)
