What is two-factor authentication and why is it important?
Two-factor authentication (2FA) adds an extra layer of security by requiring two forms of verification before access.
How does 2FA work?
2FA typically involves something you know (like a password) and something you have (like a smartphone app or SMS code).
Is 2FA really necessary for my accounts?
Yes, 2FA significantly reduces the risk of unauthorized access, making it much harder for attackers to compromise your accounts.
What are some common methods of 2FA?
Common methods include SMS codes, authenticator apps, and hardware tokens.
Can I use 2FA for all my online accounts?
Most major online services offer 2FA, but it's best to check the security settings of each account.
