Which type of two factor authentication is the most effective?
Two Factor Authentication is very useful if you want to provide your accounts with more security. The idea is that you need two pieces of information to log into your account so in the case that someone obtains your password, they will still not be able to access your account.
Here are a few types of two factor authentication:
A secondary password, pin or pattern
An email confirmation code
A phone confirmation code
Some websites use two factor authentication whenever you log in if you enabled it, while others have it when you log in with a new device. My question is which type of two factor authentication is the most effective?
Personally, I think phone confirmation code is the most effective because the code changes all the time and it is harder for hackers to get access to your phone or phone network.
