Editing 2-Factor Authentication (section)

== How to add 2-factor authentication info to KeePassXC ==
Download KeePassXC from https://keepassxc.org/download/.

# In your main database, if you have not already written your Rose-Hulman username and password in the database: Make a new entry for your Rose-Hulman network account. Go to Entries > New Entry. Enter your username and password and click OK. Press <code>Ctrl + S</code> to save the KeePass database.
# Make a separate database for your 2-factor authentication tokens and keep it in a different location (e.g., off of cloud storage and on your hard drive only). This is recommended for security reasons. Source: [https://keepassxc.org/docs/#faq-security-totp KeePassXC FAQ]
# Make a new entry called "RHIT 2-Factor" for your RHIT 2-factor authentication token in that database. Go to Entries > New Entry. You can leave username and password blank. (You can call it something else, but I use this name for the purposes of this tutorial.)
# In the entry, go to Advanced > Attachments. Click "Add" and add the QR code image that you downloaded in your Downloads folder. Click OK at the bottom and press Ctrl + S inside of KeePassXC.
# Delete the QR code image from your Downloads folder.
# We will now read the QR code to get the 2-factor authentication "secret". This is how KeePassXC generates the 2-factor authentication code you use to log in.
## On Linux or Windows Subsystem for Linux, you can read a QR code through the <code>zbarimg</code> tool. To do this, open up a terminal (<code>Ctrl+Alt+T</code> on most Linux distros) and perform the following commands:
### Ubuntu-based distros: <code>apt-get install zbar-tools</code>
### Type <code>cd ~/Downloads</code> (may be different on Windows) and then type <code>zbarimg <whatever you saved your image as>.png</code>
### You should see something like this text (YOUR_EMAIL and SOME_STRING_OF_LETTERS_AND_NUMBERS are different since it's a different user that generated the QR code, but you should see your network email under YOUR_EMAIL and a bunch of letters and numbers under SOME_STRING_OF_LETTERS_AND_NUMBERS):
#### <code>QR-Code:otpauth://totp/Rose-Hulman%20Institute%20of%20Technology%3AYOUR_EMAIL%40rose-hulman.edu?secret=SOME_STRING_OF_LETTERS_AND_NUMBERS&issuer=Microsoft</code>
### Copy the text under SOME_STRING_OF_LETTERS_AND_NUMBERS and put it into a blank text document (e.g. through Notepad). This is called the '''secret'''.
# Right-click on the KeePassXC entry called "RHIT 2-Factor" and go to TOTP > Set Up TOTP.
# Paste in the '''secret''' you put in a blank text document and paste it under "Secret Key". Leave all the other settings alone and click OK.
# Press <code>Ctrl + S</code>. Go back to 5. and then look at 1. under that inside the "Look Here First - Getting Started" section.
