Two-factor authentication is an approach to authentication which requires the presentation of “two or more” of the three authentication “factors” (“something the user knows”, “something the user has”, and “something the user is”).
The first factor is your PIN number – “Something you know”. The second factor is the token itself, the code it generates is – “something you have”. This combination helps us verify your identity. To generate the code just press the button on the front of the token and a code will be displayed for several seconds. If you miss it just press the button again.
You’ll notice that the code will change frequently. There’s no need to turn off the token it will turn off automatically after several seconds.
