[HDGEM] Two-factor authentication (2FA) is an additional layer of security that can protect your account when your password has already been stolen by malicious hackers.

Two-factor authentication codes are generated based on several variables, including a secret seed and a timestamp. The seed is unique every time it's generated, and the time variable creates a new seed generally every 30 seconds. In order for a 2FA code to be generated, the company's server needs to share a secret seed with the user's local application. This is usually done by encoding the seed in a QR code, which can then be captured by an authenticator app by scanning it.
