Just about any account you own on the internet is prone to being hacked. After numerous widespread breaches through the past years, tech companies are now working together to develop a standard that would make passwords a thing of the past, replacing them with more secure methods like biometric or PIN-based logins that do not require transferring data over the internet.
But while those standards are still being adopted, the next best way to secure your accounts is two-factor authentication, or 2FA. This a process that gives web services secondary access to the account owner (you) in order to verify a login attempt. Typically, this involves a phone number and / or an email address. This is how it works: when you log into a service, you use your mobile phone to verify your identity by either clicking on a texted / emailed link, or by typing in a number sent by an authenticator app.
