Why is Multi-Factor Authentication Important?
System access is normally granted through passwords. If a password is compromised, a hacker can then access private company and/or personal information. Users can fail to meet password security best practices by writing them down in order to remember them, using the same password for every account, or using too simple a password.
Add in the risk of phishing attacks and social engineering, and passwords are very vulnerable, which makes the information they store vulnerable as well. Multi-factor authentication adds additional security on top of the traditional password.
What is it?
Multi-factor authentication reduces the risks associated with password compromise. Multi-factor authentication requires something you know (such as a password) as well as something unique to you (a biometric scan of a fingerprint or your iris) or something you have (an access card, a random passcode) prior to granting access.
The most common form of multi-factor authentication is a password, followed by a temporary passcode being sent to your phone before access is granted.
When multi-factor authentication is enabled, an attacker who gained access to your password would need to also have access to your phone in order to log in to your account.
Check the services you use and see if multi-factor authentication is available, and utilize it whenever possible. It will generally be located within your Settings. You may have to check the service’s help in order to find out exactly where to turn on multi-factor authentication.
