2FA/MFA
2FA (Two-Factor Authentication) or MFA (Multi-Factor Authentication) is a security method that requires users to prove their identity in two or more ways before accessing systems or data. Think of it like using both a key and a security code to enter a building, rather than just a key alone. This makes it much harder for unauthorized people to gain access, even if they discover someone's password. When companies say they need someone with 2FA/MFA experience, they're looking for professionals who can help set up and manage these extra security steps to protect company accounts and data.
