To get started, run the following command:

Allow the command to update your Two-Factor Authentication. After running the
command, you’ll be asked a couple of questions, the first one being:
This one you need to answer 'yes'(y).
Do you want authentication tokens to be time-based (y/n)

You’ll then be presented with a secret key and multiple “scratch codes”.
We strongly suggest saving these emergency scratch codes in a safe place,
like a password manager. These codes are the only way to regain access if

You’ll then be prompted with several questions, The choices are all
about balancing security with ease-of-use. It begins with:

You will need to answer 'yes'(y) for two-factor authentication to work with your login.
Next question we also suggest answering yes to prevent a replay attack:
Do you want to disallow multiple uses of the same authentication
token? This restricts you to one login about every 30s, but it
increases your chances to notice or even prevent
man-in-the-middle attacks (y/n)

For security reasons we strongly suggest answering 'no'(n) to this next question:
By default, tokens are good for 30 seconds and in order to
compensate for possible time-skew between the client and the server,
we allow an extra token before and after the current time. If you
experience problems with poor time synchronization, you can increase
the window from its default size of 1:30min to about 4min.

On the next question we suggest answering 'yes'(y) since rate-limiting
means that a remote attacker can only attempt a certain number of guesses
before being blocked.
If the computer that you are logging into isn't hardened against
brute-force login attempts, you can enable rate-limiting for the
authentication module. By default, this limits attackers to no more
than 3 login attempts every 30s.

Now you're configured. You can now login without an SSH key. Make sure you
know your account password because login using two-factor authentication will
still require your password before letting you in.
