It is worth noting that the expiration time should be set based on the requirements of your application. If the current time is after the expiration time specified in the JWT, the JWT is considered invalid. When the JWT is verified, the verifier can check the expiration time to ensure that the JWT has not yet expired. The resulting datetime object is then included in the payload as the “exp” claim. In this example, we set the expiration time to 1 hour from the current time by using the datetime.timedelta function to calculate the difference between the current time and the desired expiration time. Print(token) # b'eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9.eyJzdWIiOiAiYWRtaW4iLCAiZXhwIjogMTU4NjQ1ODI5NX0.0zY4Y-4k4pWOaq8lFZN1C3J3qkm3x7zM26vjbWWYtZk' Token = jwt.encode(payload, secret, algorithm="HS256") # Create a JWT token with a subject claim "admin" and an expiration time of 1 hour If username = "admin" and password = "password": Next, we can create a function that takes a username and password as input and returns a JWT token if the credentials are valid: def authenticate(username, password): First, we will need to import the necessary modules and set up our JWT secret: import jwt To provide an example of using JWT in Python, let’s consider a simple example where we want to authenticate a user using a JWT.

By the end of this tutorial, you should have a solid understanding of how to use JWT in your Python projects. Additionally, we will discuss techniques for decoding JWT tokens and explore options for working with and refreshing JWT tokens in Python.
We will also introduce the Python JWT module and go over the process of signing and verifying JWT tokens. Welcome to this tutorial on using JWT (JSON Web Tokens) in Python! In this guide, we will cover the basics of JWT and provide an example of using JWT in Python.
