Set Jwt Key

---

1. Open Command Prompt:

   • Press Win + R to open the Run dialog.
   • Type cmd and press Enter to open Command Prompt.

2. Check Existing Environment Variables (Optional):

   • You can check existing environment variables using the echo %VARIABLE_NAME% command.

3. Set JWT Key as Environment Variable:

   • Use the setx command to set the JWT key as an environment variable. Replace YOUR_JWT_KEY with your actual JWT key.

     bashCopy code

     setx JWT_KEY "YOUR_JWT_KEY"

4. Verify the Environment Variable:

   • To verify that the variable has been set, you can use the echo %JWT_KEY% command.

5. Restart Any Affected Applications (If Necessary):

   • Some applications might require a restart to pick up the new environment variable.

6. Confirm Environment Variable Persistence:

   • The setx command may not affect the current Command Prompt session. Open a new Command Prompt and verify the environment variable using echo %JWT_KEY%.

7. Done:

   • You have successfully added the JWT key as an environment variable using the setx command.

Note:

• Make sure to replace YOUR_JWT_KEY with your actual JWT key.
• Be cautious while setting environment variables, as they can impact system behavior.
• Use the appropriate syntax and quotes, especially if your JWT key contains spaces or special characters.
