Push button in Security key used for 2FA/MFA
I have come across many security keys from different manufacturers such as solokeys, yubico etc.., for the purposes of 2FA/MFA. Products vary basically w.r.t features such as USB-A, USB-C, Apple connector or NFC. But, I could not still figure out the reason for having a push button in couple of products whereas the nano products do not have that push button. So, does the push button offer extra security in any manner? or if the push button is not available, is the key open to security risks?
