Fortytwo offers a two-factor authentication solution that enhances security by sending a verification code to users' mobile phones, addressing vulnerabilities related to weak or stolen passwords. The process involves an API request for authentication, sending a one-time code via SMS, and requiring this code for successful login validation. Fortytwo's system, backed by a multilingual support team and global messaging networks, is designed to protect against various forms of remote attacks.

your customers more securely, by

mobile phone.
Two-Factor
Authentication

2. Passwords aren't as secure as they used to be and if
someone gets a hold off a user’s password, they may
be able to compromise the account without any
difficulty. Even stronger passwords are at risk of
compromise.
Two-factor authentication
solves this problem
Two-factor authentication is one of the best ways to
protect against remote attacks such as phishing,
brute-force, credential exploitation and other attempts
to take over an account. Without the physical device,
remote attackers can’t pretend to be the account
holder in order to gain unauthorized access.
A password is now the
weakest link
76% of attacks on
corporate networks
involved weak or stolen
passwords.

3. Two-factor authentication provides a second layer of security to any type of
login by requiring extra information or a physical device for access, in addition
to the username and password.
The factors may include:
Something you know - a unique username and password
Something you have - a phone
Something you are – such as a biometric fingerprint, voice print or retina scan
By choosing two different channels of authentication, you can better protect
your users’ logins from remote attacks.
Why two-factor authentication?

6. Valid/Invalid Response
Once the user's login details has been captured, an authentication request is sent to Fortytwo
through an API. Fortytwo will process the request and send a verification code to the user's mobile
phone by SMS. The user will need to enter the code on the login page to verify their credentials. A
validation request is then sent back to Fortytwo, which will return a valid or invalid response.

5. Verification code
The verification code sent to the user’s
mobile phone is a one-time code. The
code can either be numeric, alpha or
alphanumeric. As a client, you can also
choose the character length of the code
and if it’s case sensitive. As a default,
codes are 6 digits and numeric.
The code is only valid for 5 minutes for
each transaction request.
