A second check on top of your password
Two-factor authentication asks for something beyond the password, usually a code generated on the spot. Because a crypto transfer cannot be reversed, protecting the account carries more weight than elsewhere. Codes from an authenticator app are considered harder to steal than codes sent by SMS. Recovery codes are written down and kept somewhere separate.
The common form is a 6-digit code that changes every 30 seconds.
