Two-factor authentication (2FA) or two-step authentication (2SA) is a security feature that helps protect your account in addition to your password.
When two-factor authentication enabled, you log in to your account by entering your username and password as normal. The site will then prompt you to enter a code that is either configured on your application (Google Authenticator) or sent to your phone by text message. This one-time code, or one-time password (OTP), is only valid for a limited time, usually no more than five minutes, and can only be accessed by someone with access to this application or phone.
Therefore even if hacker has a password for your account he will not be able to enter it, since the system will require additional login confirmation, based on the method you have chosen:
- sms code sent to your mobile phone;
- login code generated by the application installed on your device (PC, mobile phone).
EXMO recommends to install two-factor authentication on EXMO account, as well as on EXMO registration mail.
