Since someone tried to hack my bank account I\ve become very concerned about internet security. I've read a lot of professional and useful articles, the most I liked this https://www.safetydetective.com/blog/what-is-phishing-and-how-to-protect-against-it/ for simple and friendly writing style. But I hardly understand should I use two-factor authentication on all sites or only on important ones like my banking account?

2 Auth is a way to notify you on multiple contacts so you know what is happening to your account. An example of 2 Auth is through messages or emails.

What? Are you joking? This is completely wrong. It simply requires a 2nd form of identification, normally in addition to a password. 2FA typically uses a physical device, like a USB stick (such as FIDO), to store credentials. This physical device must be present and used each time you log in. This only works for accounts that support 2FA, such as gmail. This prevents someone from stealing or guessing your password.and logging in, since they would not have your additional credentials. Aside from the inconvenience, the risk is that the physical device is lost or damaged, so you need an extra one to use as a backup. You can associate multiple sets of additional credentials with a single account that supports 2FA. 2FA is typically used for primary email accounts that would, for example, be used to reset passwords.

Both of you could simply google it. There's no reason to post a question like this in this forum.

What? Are you joking? 2FA AKA MFA certainly does not need at all to be used with a physical device?!?!?
Apparently someone else should Google it, too. ;)

Learn how to read troll. "2FA typically uses a physical device". See that word "typically"? When people are discussing 2FA to protect their accounts, that is what they are normally referring to, not what the first response claimed.
