The Descope SDK for python provides convenient access to the Descope user management and authentication API for a backend written in python. You can read more on the Descope Website.
The SDK supports Python 3.7 and above.
Install the package with:
pip install descope
A Descope Project ID
is required to initialize the SDK. Find it on the
project page in the Descope Console.
from descope import DescopeClient
# Initialized after setting the DESCOPE_PROJECT_ID env var
descope_client = DescopeClient()
# ** Or directly **
descope_client = DescopeClient(project_id="<Project ID>")
Here are some examples how to manage and authenticate users:
Send a user a one-time password (OTP) using your preferred delivery method (email / SMS). An email address or phone number must be provided accordingly.
The user can either sign up
, sign in
or sign up or in
from descope import DeliveryMethod
# Every user must have a login ID. All other user information is optional
email = "[email protected]"
user = {"name": "Desmond Copeland", "phone": "212-555-1234", "email": email}
masked_address = descope_client.otp.sign_up(method=DeliveryMethod.EMAIL, login_id=email, user=user)
The user will receive a code using the selected delivery method. Verify that code using:
jwt_response = descope_client.otp.verify_code(
method=DeliveryMethod.EMAIL, login_id=email, code=value
)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
Send a user a Magic Link using your preferred delivery method (email / SMS). The Magic Link will redirect the user to page where the its token needs to be verified. This redirection can be configured in code, or generally in the Descope Console
The user can either sign up
, sign in
or sign up or in
from descope import DeliveryMethod
masked_address = descope_client.magiclink.sign_up_or_in(
method=DeliveryMethod.EMAIL,
login_id="[email protected]",
uri="http://myapp.com/verify-magic-link", # Set redirect URI here or via console
)
To verify a magic link, your redirect page must call the validation function on the token (t
) parameter (https://your-redirect-address.com/verify?t=<token>
):
jwt_response = descope_client.magiclink.verify(token=token)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
Using the Enchanted Link APIs enables users to sign in by clicking a link delivered to their email address. The email will include 3 different links, and the user will have to click the right one, based on the 2-digit number that is displayed when initiating the authentication process.
This method is similar to Magic Link but differs in two major ways:
- The user must choose the correct link out of the three, instead of having just one single link.
- This supports cross-device clicking, meaning the user can try to log in on one device, like a computer, while clicking the link on another device, for instance a mobile phone.
The Enchanted Link will redirect the user to page where the its token needs to be verified. This redirection can be configured in code per request, or set globally in the Descope Console.
The user can either sign up
, sign in
or sign up or in
resp = descope_client.enchantedlink.sign_up_or_in(
login_id=email,
uri="http://myapp.com/verify-enchanted-link", # Set redirect URI here or via console
)
link_identifier = resp["linkId"] # Show the user which link they should press in their email
pending_ref = resp["pendingRef"] # Used to poll for a valid session
masked_email = resp["maskedEmail"] # The email that the message was sent to in a masked format
After sending the link, you must poll to receive a valid session using the pending_ref
from
the previous step. A valid session will be returned only after the user clicks the right link.
i = 0
while not done and i < max_tries:
try:
i = i + 1
sleep(4)
jwt_response = descope_client.enchantedlink.get_session(pending_ref)
done = True
except AuthException as e: # Poll while still receiving 401 Unauthorized
if e.status_code != 401: # Other failures means something's wrong, abort
logging.info(f"Failed pending session, err: {e}")
done = True
if jwt_response:
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
To verify an enchanted link, your redirect page must call the validation function on the token (t
) parameter (https://your-redirect-address.com/verify?t=<token>
). Once the token is verified, the session polling will receive a valid jwt_response
.
try:
descope_client.enchantedlink.verify(token=token)
# Token is valid
except AuthException as e:
# Token is invalid
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
Users can authenticate using their social logins, using the OAuth protocol. Configure your OAuth settings on the Descope console. To start a flow call:
descope_client.oauth.start(
provider="google", # Choose an oauth provider out of the supported providers
return_url="https://my-app.com/handle-oauth", # Can be configured in the console instead of here
)
The user will authenticate with the authentication provider, and will be redirected back to the redirect URL, with an appended code
HTTP URL parameter. Exchange it to validate the user:
jwt_response = descope_client.oauth.exchange_token(code)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
Users can authenticate to a specific tenant using SAML or Single Sign On. Configure your SSO/SAML settings on the Descope console. To start a flow call:
descope_client.saml.start(
tenant="my-tenant-ID", # Choose which tenant to log into
return_url="https://my-app.com/handle-saml", # Can be configured in the console instead of here
)
The user will authenticate with the authentication provider configured for that tenant, and will be redirected back to the redirect URL, with an appended code
HTTP URL parameter. Exchange it to validate the user:
jwt_response = descope_client.saml.exchange_token(code)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
The user can authenticate using an authenticator app, such as Google Authenticator.
Sign up like you would using any other authentication method. The sign up response
will then contain a QR code image
that can be displayed to the user to scan using
their mobile device camera app, or the user can enter the key
manually or click
on the link provided by the provisioning_url
.
Existing users can add TOTP using the update
function.
from descope import DeliveryMethod
# Every user must have a login ID. All other user information is optional
email = "[email protected]"
user = {"name": "Desmond Copeland", "phone": "212-555-1234", "email": email}
totp_response = descope_client.totp.sign_up(method=DeliveryMethod.EMAIL, login_id=email, user=user)
# Use one of the provided options to have the user add their credentials to the authenticator
provisioning_url = totp_response["provisioningURL"]
image = totp_response["image"]
key = totp_response["key"]
There are 3 different ways to allow the user to save their credentials in their authenticator app - either by clicking the provisioning URL, scanning the QR image or inserting the key manually. After that, signing in is done using the code the app produces.
jwt_response = descope_client.totp.sign_in_code(
login_id=email,
code=code, # Code from authenticator app
)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
The user can also authenticate with a password, though it's recommended to prefer passwordless authentication methods if possible. Sign up requires the caller to provide a valid password that meets all the requirements configured for the password authentication method in the Descope console.
# Every user must have a login_id and a password. All other user information is optional
login_id = "[email protected]"
password = "qYlvi65KaX"
user = {
"name": "Desmond Copeland",
"email": login_id,
}
jwt_response = descope_client.password.sign_up(
login_id=login_id,
password=password,
user=user,
)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The user can later sign in using the same login_id and password.
jwt_response = descope_client.password.sign_in(login_id, password)
session_token = jwt_response[SESSION_TOKEN_NAME].get("jwt")
refresh_token = jwt_response[REFRESH_SESSION_TOKEN_NAME].get("jwt")
The session and refresh JWTs should be returned to the caller, and passed with every request in the session. Read more on session validation
In case the user needs to update their password, one of two methods are available: Resetting their password or replacing their password
Changing Passwords
NOTE: send_reset will only work if the user has a validated email address. Otherwise password reset prompts cannot be sent.
In the password authentication method in the Descope console, it is possible to define which alternative authentication method can be used in order to authenticate the user, in order to reset and update their password.
# Start the reset process by sending a password reset prompt. In this example we'll assume
# that magic link is configured as the reset method. The optional redirect URL is used in the
# same way as in regular magic link authentication.
login_id := "[email protected]"
redirect_url := "https://myapp.com/password-reset"
descope_client.password.send_reset(login_id, redirect_url)
The magic link, in this case, must then be verified like any other magic link (see the magic link section for more details). However, after verifying the user, it is expected to allow them to provide a new password instead of the old one. Since the user is now authenticated, this is possible via:
# The refresh token is required to make sure the user is authenticated.
err := descope_client.password.update(login_id, new_password, token)
update
can always be called when the user is authenticated and has a valid session.
Alternatively, it is also possible to replace an existing active password with a new one.
# Replaces the user's current password with a new one
descope_client.password.replace(login_id, old_password, new_password)
Every secure request performed between your client and server needs to be validated. The client sends the session and refresh tokens with every request, and they are validated using one of the following:
# Validate the session. Will raise if expired
try:
jwt_response = descope_client.validate_session(session_token)
except AuthException:
# Session expired
# If validate_session raises an exception, you will need to refresh the session using
jwt_response = descope_client.refresh_session(refresh_token)
# Alternatively, you could combine the two and
# have the session validated and automatically refreshed when expired
jwt_response = descope_client.validate_and_refresh_session(session_token, refresh_token)
Choose the right session validation and refresh combination that suits your needs.
Refreshed sessions return the same response as is returned when users first sign up / log in, containing the session and refresh tokens, as well as all of the JWT claims. Make sure to return the tokens from the response to the client, or updated the cookie if you're using it.
Usually, the tokens can be passed in and out via HTTP headers or via a cookie. The implementation can defer according to your framework of choice. See our samples for a few examples.
If Roles & Permissions are used, validate them immediately after validating the session. See the next section for more information.
When using Roles & Permission, it's important to validate the user has the required
authorization immediately after making sure the session is valid. Taking the jwt_response
received by the session validation, call the following functions:
For multi-tenant uses:
# You can validate specific permissions
valid_permissions = descope_client.validate_tenant_permissions(
jwt_response, "my-tenant-ID", ["Permission to validate"]
)
if not valid_permissions:
# Deny access
# Or validate roles directly
valid_roles = descope_client.validate_tenant_roles(
jwt_response, "my-tenant-ID", ["Role to validate"]
)
if not valid_roles:
# Deny access
When not using tenants use:
# You can validate specific permissions
valid_permissions = descope_client.validate_permissions(
jwt_response, ["Permission to validate"]
)
if not valid_permissions:
# Deny access
# Or validate roles directly
valid_roles = descope_client.validate_roles(
jwt_response, ["Role to validate"]
)
if not valid_roles:
# Deny access
You can log out a user from an active session by providing their refresh_token
for that session.
After calling this function, you must invalidate or remove any cookies you have created.
descope_client.logout(refresh_token)
It is also possible to sign the user out of all the devices they are currently signed-in with. Calling logout_all
will
invalidate all user's refresh tokens. After calling this function, you must invalidate or remove any cookies you have created.
descope_client.logout_all(refresh_token)
It is very common for some form of management or automation to be required. These can be performed using the management API. Please note that these actions are more sensitive as they are administrative in nature. Please use responsibly.
To use the management API you'll need a Management Key
along with your Project ID
.
Create one in the Descope Console.
from descope import DescopeClient
# Initialized after setting the DESCOPE_PROJECT_ID and the DESCOPE_MANAGEMENT_KEY env vars
descope_client = DescopeClient()
# ** Or directly **
descope_client = DescopeClient(project_id="<Project ID>", management_key="<Management Key>")

To ease your e2e tests, we exposed dedicated management methods, that way, you don't need to use 3rd party messaging services in order to receive sign-in/up Emails or SMS, and avoid the need of parsing the code and token from them.
# User for test can be created, this user will be able to generate code/link without
# the need of 3rd party messaging services.
# Test user must have a loginId, other fields are optional.
# Roles should be set directly if no tenants exist, otherwise set
# on a per-tenant basis.
descope_client.mgmt.user.create_test_user(
login_id="[email protected]",
email="[email protected]",
display_name="Desmond Copeland",
user_tenants=[
AssociatedTenant("my-tenant-id", ["role-name1"]),
],
)
# Now test user got created, and this user will be available until you delete it,
# you can use any management operation for test user CRUD.
# You can also delete all test users.
descope_client.mgmt.user.delete_all_test_users()
# OTP code can be generated for test user, for example:
resp = descope_client.mgmt.user.generate_otp_for_test_user(
DeliveryMethod.EMAIL, "login-id"
)
code = resp["code"]
# Now you can verify the code is valid (using descope_client.*.verify for example)
# Same as OTP, magic link can be generated for test user, for example:
resp = descope_client.mgmt.user.generate_magic_link_for_test_user(
DeliveryMethod.EMAIL, "login-id", ""
)
link = resp["link"]
# Enchanted link can be generated for test user, for example:
resp = descope_client.mgmt.user.generate_enchanted_link_for_test_user(
"login-id", ""
)
link = resp["link"]
pending_ref = resp["pendingRef"]
# Note 1: The generate code/link functions, work only for test users, will not work for regular users.
# Note 2: In case of testing sign-in / sign-up operations with test users, need to make sure to generate the code prior calling the sign-in / sign-up operations.
Handle API rate limits by comparing the exception to the APIRateLimitExceeded exception, which includes the RateLimitParameters map with the key "Retry-After." This key indicates how many seconds until the next valid API call can take place. More information on Descope's rate limit is covered here: Descope rate limit reference page
try:
