2FA is actually less secure than a strong password. Phone accounts can be easily hacked via various methods. In fact, I am suspecting that OP is really a hacker that is trying to make Polo accounts less secure by getting them to require 2FA.
Accounts with 2FA allow a password reset using your phone, that is how Coinbase accounts get hacked all the time. If you don't use 2FA on your Coinbase account, you can't be hacked with a strong password.
2FA = hacker's wet dream
2FA is like requiring home owners to put multiple locks on their guns so that they can't quickly arm themselves if they get robbed.
I just used my Keepass to generate this 24 digit password: Ã:äPrQÕ¾+N=í©Sÿ3ƽ§«7Ùà2
I checked the generator and there are a potential of over a hundred different characters, so 100^24 = over 10^48 possible combinations.
There is no way OP can hack 10^48 possible combinations, so he wants to degrade security by using the 2FA back door method.
This is how you know OP is a hacker.
