Python
Authenticate requests and manage Passage users with Python.
To use the Passage Python SDK, you'll need your Passage App ID. You can create a new Passage App in the console.
The Passage Python SDK is designed for Flask or Django apps and supports Python 3.6 and higher.
It can be installed from the command line:
pip install passage-identityA Flask server can easily authenticate an HTTP request using the
passageidentity package, available via pip. The example below shows a Flask middleware that can be used to authenticate users.from passageidentity import Passage
import os
PASSAGE_APP_ID = os.environ.get("PASSAGE_APP_ID")
class AuthenticationMiddleware(object):
def __init__(self, app):
self.app = app
def __call__(self, environ, start_response):
request = Request(environ)
psg = Passage(PASSAGE_APP_ID)
try:
user = psg.authenticateRequest(request)
except:
ret = Response(u'Authorization failed', mimetype='text/plain', status=401)
return ret(environ, start_response)
environ['user'] = user
return self.app(environ, start_response)
By default, Passage looks for the user JWT from a cookie that is set by the Passage Element (
psg_auth_token ). If your application uses Authorization headers instead, you can pass the following option to Passage.psg = Passage(PASSAGE_APP_ID, authStrategy=Passage.HEADER_AUTH)
It is important to remember that
psg.authenticateRequest() validates that a request is properly authenticated, but an additional authorization check is often required.app = Flask(__name__)
app.wsgi_app = AuthenticationMiddleware(app.wsgi_app)
@app.route('/', methods=['GET', 'POST'])
def authenticatedRoute():
passageID = environ['user']
authorized = authorizationCheck(passageID)
if authorized:
# Successful authentication and authorization. Proceed ...
The Passage SDK provides a way to retrieve information about an app.
from passageidentity import Passage
psg = Passage(PASSAGE_APP_ID)
passageAppInfo = psg.getApp()
print(passageAppInfo)
In addition to authenticating requests, the Passage SDK also provides a way to securely manage your users. These functions require authentication using a Passage API key. API keys can be managed in the Passage Console.
Passage API Keys are sensitive! You should store them securely along with your other application secrets.
The functionality currently available on a user is:
- Get a user's information (including any defined user metadata)
- Activate or deactivate a user (a deactivated user will not be able to log in)
- Update a user's information (email address or phone number)
- Delete a user
- Create a user

from passageidentity import Passage
import os
PASSAGE_APPID = os.environ.get("PASSAGE_APPID")
PASSAGE_API_KEY = os.environ.get("PASSAGE_API_KEY")
psg = Passage(PASSAGE_APPID, PASSAGE_API_KEY)
def exampleFlaskMiddleware(request):
g.user = psg.authenticateRequest(request)
@app.route('/home')
def authenticatedEndpoint():
user = psg.getUser(g.user)
print(user.email)
from passageidentity import Passage

# get Passage UserID from database
# ...
# create user via email
created_user1 = psg.createUser({"email": "[email protected]"})
print(created_user1) # Passage UserObject
# create user via phone
created_user2 = psg.createUser({"phone": "+15005550007"})
print(created_user2) # Passage UserObject
All fields available in a Passage User object are listed below:
Field | Type |
id | string |
email | string |
phone | string |
active | boolean |
email_verified | boolean |
created_at | datetime |
last_login_at | datetime |
webauthn | boolean |
user_metadata | dictionary |
webauthn_devices | array of strings (e.g. "Mac OS X") |
recent_events | array of PassageEvents |
The functionality currently available is:
- List all devices for a user
- Revoke a particular device from a user
List Devices
Revoke Device

print(succes) #true
The Python SDK can be used to generate custom magic links (called "smart links") for users, that can be embedded into any content medium. To learn more, see our full guide on Smart Links.
from passageidentity import Passage
psg = Passage(PASSAGE_APP_ID, PASSAGE_API_KEY)
# create a magic link
magicLinkAttributes={
"email": "<[email protected]>",
"redirect_url": "/custom-path/1234"}
magicLink = psg.createMagicLink(magicLinkAttributes)
# use the 'url' parameter
print(magicLink.url)
