Determining who you are is called “authentication.”
This is a process that we encounter all the time. Every time we log in, we’re authenticating to a system.
Usually, we do this with a unique username and password. To provide additional security and assurances, multi-factor authentication is highly recommended.
Multi-factor or two factor authentication is when—in addition to a username and password—the user requires another way of identifying themselves. This often generates a one-time code for a smartphone app or via text message.
The security concept behind this approach is simple. Now to get into an account you must:

Honestly, the username is typically public knowledge. It’s often
