What is SMS-Based Two-Factor Authentication?

Two-factor authentication is a security process where users provide two different types of evidence to verify their identity. Typically, this means something you know (like a password) and something you have (like a phone). SMS-based two-factor authentication sends a one-time code via text message to the user’s mobile phone when they try to login or perform sensitive actions. The user then enter this code along with their password to gain access.

This extra layer of security makes it much harder for hackers to access accounts, because even if they steal a password, they would also need the physical phone to get the SMS code. SMS 2FA is popular because it doesn’t require special apps or hardware tokens, making it accessible for many people.
