Python Quick Tip: Hiding Passwords and Secret Keys in Environment Variables (Mac & Linux)

in linux after you save your enviroment variables you have to type source .bashrc before restarting your text editor :)

how is having plain text passwords in environment variables secure?

some reason i just get print of none

And what about the .env file?

Instead of using os.environ.get(), you can now just use os.getenv()

Thank you for your help!!

This video is outdated for latest version of mac

Why does this print?
None
None

million 🔥
Congratulations

Easy & fantastic tutorial ! I will definitely use this method to hide my credentials on python boto3 script lol

Amazing

Is there a way to parse this to Powershell?

I've been searching for a solution like this for several days... this solved so many of my headaches.

I used a pip3 package o do this, but now I think this is simpler and easier..

use this cmd `source .bash_profile` after saving the `.bash_profile` file

I keep getting a smtplib.SMTPSenderRefused on video 0 of flask series
How do I check that my environmental variables are correct?

LOVE IT, nobody has explained better! thanks a lot!

Corey MS ❤️❤️❤️❤️ your python videos are pure gold 🥰🥰🥰🥰🥰

thx

Hi Corey! Great video. If I input print(EMAIL_ADDRESS, should I get 'None' as my output?

How do you make this work using a virtual environment?

Thank You

Sir Corey comeback man!!

nice ;) thx

I'm running Ubuntu 20.04 and the test script returned 'None' for me until I added the environment variables to ~/.bashrc instead of .bash_profile. So, it seems that the proper procedure may vary with each distribution of Linux.

very helpful, thanks a lot

Talented Teacher. Thanks for your pains. I want to one day build a python package for physics. Your lectures are great help.

Thanks for this quick and concise explanation. Is this any more secure than hard-coding the password however? Couldn't someone cat your .bash_profile to see the password, or perform some other trickery to access it?

Pretty helpful. But when print the variables, i get a None type back.

you saved my life again!

I think I should worship you for the rest of my life. You are always the savior.

thank you for making sense of this for me - was struggling to understand it in text form only! :)

In my experience, environment variables also serve one important purpose other than maintaining secrecy. By using of environment variables instead of hard coded values I could easily roll out my project without worrying about the API keys and other settings used in the development version updated before uploading source code to the deployment server.🔥

Your explanations are great.

no idea what just happened.

@ Corey Schafer
Thanks for sharing.But it didn't work on AWS linux2 after modify .bash_profile.
How can I do ? Thnak you!!

Great information as always, but I was wondering if I could use a separate text file for holding my credentials and then load it into my python module, I can add that text file in my .gitignore so it will not be pushed. I mean it won't be nice if I generate too many environment variables, it would be confusing if I am working on multiple projects.

Hey I'm getting an error when I request a password reset that says 'get_reset_token() missing 1 required positional argument: 'self''. Any idea what could be causing this? I've coped your code from your github so I'm confident I have exactly what you have!

Still very useful 3 years later. Great videos. Btw, how do you manage credentials on scripts that will be hosted online for instance?

Hi , Nice tutorial, just a quick question, will this work the same if the code is pushed to a remote server?

How can i be able to access this value in some other machine if I want to??

depending on the shell you are using, look for corresponding .xxrc file. (e.g. if you use zsh, .zshrc; if bash, then .bashrc)

plz show me how to use this in the virtual env (venv) for windows

How about creating a separate file for security data, then adding that file to gitignore, and reading the necessary data from that file when needed?

I get None

If you are using Linux Box , the solution is to put your environment variables in "/etc/environment".

Example in your /etc/environment file:
------------------------------------------------------------------------------------
DB_USER="Y=User name"
DB_PASS="Your Password"
-------------------------------------------------------------------------------------
And reboot your computer. you will have access to them in your python files using:

import os
DB_USER=os.environ["DB_USER"]

can you save the py file anywhere on the computer ??? does it matter??

It didnt work for me i kept getting none
