Two Factor Authentication

You've probably seen two-factor authentication before (aka those annoying texts and emails), but let's go a bit into the theory.

A brief note: Cell phone text messages aka SMS are commonly used for multifactor auth. These are not great, because a) someone can steal your phone number and get the texts sent to them b) intercept your text messages

However, those things are not in your threat model unless you are famous or have cryptocurrency wallets. So don't worry about it, SMS 2FA is great.

Another note: Just because you have multi-factor doesn't mean you can't get phished for it!
