2FA (Two-Factor Authentication) is a security measure used to protect accounts by requiring two forms of verification before granting access. It helps prevent unauthorized access, even if someone has your password.
Typically, 2FA involves:
- Something You Know – A password or PIN.
- Something You Have – A one-time code from an authenticator app, SMS, or a physical security key.
This extra layer of security makes it much harder for hackers to access your account.
