Python Flask Single Sign-On SSO
Python Flask JWT Single Sign-On (SSO) solution by miniOrange provides secure Single Sign-On access into Python Flask application using a single set of login credentials. This is done using JSON Web Token (JWT) tokens and it can be easily integrated with Python Flask built in any framework or language. You can enable social login for your users to get secure access to applications using any of their existing social providers such as Facebook, Twitter, Google, or LinkedIn.
With miniOrange Python Flask SSO, you get:
- Seamless user login experience.
- Endless customizations to your login forms and pages.
- Simplified customer or user on-boarding.
Connect with External Source of Users
miniOrange provides user authentication from various external sources, which can be Directories (like ADFS, Microsoft Active Directory, Azure AD, OpenLDAP, Google, AWS Cognito etc), Identity Providers (like Shibboleth, Ping, Okta, OneLogin, KeyCloak), Databases (like MySQL, Maria DB, PostgreSQL) and many more.
Follow the step-by-step guide given below for Python Flask Single Sign-On (SSO):
1. Configure Python Flask in miniOrange
- Go to Apps >> Add Application from the side menu.
- Click on the JWT under Choose Application Type.
- In the next step, search for Python Flask application from the list. If your application is not found, search for External / JWT App and you can set up your Application.
- You can configure the following details in the application:
| Custom App Name |
Enter the Application Name of your choice, and add a description if required. |
| Redirect-URL |
Enter the Redirect-URL (i.e. the endpoint where you want to send/post your JWT token).
You can add multiple redirect URLs by separating them with a ‘;’. E.g. abc.com;xyz.com |
| Primary Identity Provider (optional) |
Select your Identity Source from the dropdown. You can select miniOrange here as default IDP. |
- Click on Save to complete the configuration.
- Click on Edit in the select menu against your app.
- You can get further details about your recently added JWT application:
| Client ID |
If your application provides its own client ID, you can configure it by clicking on the Customize button. |
| App Secret |
You can find App Secret by clicking on the copy icon. This is used in the HS265 Signature
algorithm for generating the signature. |
| Signature Algorithm |
Select your signature algorithm from the dropdown. |
| Primary Identity Provider |
Select the default Identity Provider from the dropdown for the application. If not selected, users will see the default
login screen and can choose their own IDP. [Choose miniOrange in this case.] |
| Redirect URL |
Given below is your app URL where you will receive your token.
RSA 256 : <your_app-login-url> (Here token will be added by the system)
HS256 : <app-login-url/?id_token=> |
- Scroll down to Endpoints >> Single Sign-On URL. Save this URL as you will need this in the following configuration.
- click on Save to save the configuration.
2. Adding Script on Python Flask's End
