What are the differences between two-factor authentication and passwords?

Two-factor authentication (2FA) adds an extra layer of security beyond just passwords. While passwords are something you know, 2FA requires something you have (like a phone) or something you are (like a fingerprint). This makes it harder for unauthorized users to access your accounts.

Why is two-factor authentication considered more secure?

2FA is more secure because even if someone steals your password, they would still need the second factor to gain access. This significantly reduces the risk of unauthorized access.

Are there any downsides to using two-factor authentication?

Yes, some downsides include the potential for inconvenience, as it requires an additional step during login. Additionally, if you lose access to your second factor, you may have trouble accessing your account.

Can I use two-factor authentication with all my accounts?

Most major online services offer 2FA, but not all do. It's best to check the security settings of each service to see if they support it.
