1/ Two Factor Authentication (2FA) is an extra layer of security that proves the person accessing an account is the authentic owner.
2/ 2FA methods include authenticator apps, hardware keys, SMS codes, and more - but not all methods are equally secure.
3/ For example, SMS-based 2FA is the least safe. Hackers can...
-Obtain your personal details.
-Port your phone number to a different phone (SIM swapping).
-Then receive all texts and calls intended for you.

4/ One way to protect yourself from SIM swapping is to use a unique email address that's associated with your mobile service and nothing else. But it's better to avoid SMS-based 2FA altogether.

5/ 2FA Mobile Apps:
Apps like Authy, Microsoft Authenticator and Google Authenticator provide you with a code passcode that changes every 30 seconds.
A hacker would need to have possession of your device to breach your account.

6/ Hardware Keys:
YubiKeys, for example, provide a single-use passcode for each login instance, and they also require you to physically touch the key in order to activate it – making it impossible for a hacker to access remotely.
