Allows you to provide a code which will solve a checkpoint encountered during a native authentication. A checkpoint is a security step added by a provider which needs to be solved to complete the authentication. Checkpoints that require a code are 2FA (two-factor authentication) and OTP (one-time password). Depending on the way you have configured the account you are trying to authenticate, you can get your code from various ways such as a mail, a SMS or from a two-factor authentication app.
