The process will eventually be as follows: Click the "Enable MFA" button. A modal window will appear with a QR code, accompanied by instructions to either scan the QR code with your camera or copy and paste the code into your password management app (featuring a convenient "Copy to Clipboard" icon).
Below the QR code, there will be a text box to input and verify the code. Once the code is successfully verified, MFA will be enabled, and you will be logged out, requiring you to log back in.
