Two Factor Authentication Is Good but What Level of 2FA Do You Need
There are different levels of two factor authentication. There are some places you can sign in and the website will push out a time-limited code. It’ll come out either as an email or it’ll come out through a message to your phone. It could even go to another device with which you were also logged in to the same account.
It does offer some security extra on top of just having a username and password. The only thing is, if somebody steals your phone that also gives them access to that second factor of authentication. It’s not going to be enough, it’s a little bit too easy with regard the a man in the middle attack. Or a thief
The next level of two factor authentication protection will be to use a separate authentication app. You can put a password or a pin code which is different from your device login password to keep people out of that app.
Or you could have it Open up only with face recognition or other biometric locking mechanism like your fingerprint.
So if someone steals your phone they would need to know the password to your authenticator app which you have different to your log in pincode to the phone. If someone was shoulder surfing and saw you enter the password to the phone - Your important accounts still have another level of protection.
