Common 2FA methods:
1. Text Message - Receive a login code (SMS).
2. 2FA Application - Mobile application that generates an authentication code.
3. Bio-metric - This method requires you to physically present something to
gain access to your account. Common methods of bio-metric verification
include retina scans and fingerprint.
An account that uses 2FA is
much more secure than a mere username and password login, but that
doesn’t mean it is 100% safe.You may lose access if you lose your phone
or unable to receive the login code if your phone number is inactive.
Mobile number portability is an opening for hackers to impersonate you
and switch your number. Others may be able to use or access to your
device (apps) when it is unattended while at work or losing it while traveling. Hackers may be able to hack your device (apps).
It is
recommended that users always activate 2FA whenever it is available. And
remember to always have at least one back-up method just in case the
main 2FA method is not working / failed, you are still able to get the login code /
access. Common back-up methods are: back-up phone number and
generate a one time back-up code and save / place it someway safe.
