Bahaa Abdul Hadi feels SSO or Single Sign-On is an authentication method that allows users to have a single sign-on or credential to authenticate multiple applications. Combining SSO with Multi-Factor Authentication (MFA) ensures the highest level of security. We look at how this can be done.

How SSO works

SSO works on the basis of a trust relationship between the service provider and the identity provider. This is done in the form of a certificate or token. A master sign-on is done for authentication using an SSO application. Once this is done, the SSO application then stores the user’s credentials. These credentials are then used to authenticate users whenever they want to login to any software.

Users need to remember only password, and it can be used to sign on to all applications. While it is highly convenient for users, there are security risks involved. If a hacker gains access to the password, then they can get access to all applications. Using MFA can help in overcoming this risk and making SSO more secure.

MFA and SSO

In MFA, there are two or more authentication factors used to verify identity. This can include password, PIN, OTP, biometric factors, etc. The combination of multiple factors enhances security thus reducing the risk of security breaches. When MFA is combined with SSO, it increased user convenience while ensuring the highest levels of security. This is how it works:

  • You need to work with an SSO provider who offers a solution that can be effectively integrated with MFA.
  • The SSA solution allows the user to login once at the start of a work session. The login credentials are then saved and the same credentials used for all applications. Users need to enter the password only once.
  • Additional security layer is implemented by using MFA. It can be through the use of OTP or biometric factors. The additional layer of MFA security ensures that even if someone accesses the password they cannot gain access to the application.
  • MFA needs to be implemented in all applications. Ideally, biometrics can be used since it is convenient and user-friendly.
  • It is important to inform and educate users about how SSO and MFA works.
  • Authentication policies must be created, and they need to be reviewed regularly to ensure they are offering the highest security levels.

An integrated solution offering SSA and MFA is the best way to secure your system. It is convenient to use while ensuring no compromise on data security.
