Two-factor authentication in Salesforce
Two-factor authentication in Salesforce is a two-step login process. You can enable it if your users need more security rather than the ordinary login process. In this process, once the user logs in using their username and password, a token or passcode is sent to their device, which they need to enter in order to finally log in.
Time-based tokens can now be used as a substitute to SMS-based (not available for non-English organizations) and e-mail-based login verification to activate a computer:
