I've been using 1Password for a while and recently decided to purchase a yubikey as an extra layer of protection.
I noticed that in order to enable U2F I needed to firstly create a 2FA. I understand that this is a backup in case I lose the yubikey.
So my question is this: does the U2F provide anything other than ease of use?
I was under the impression that U2F is safer than 2FA apps. But if I have to use both of them, is it really safer since the true strength of the chain depends on how strong the weakest of the links is.
I am not sure which category this belongs to, sorry if I chose the wrong one.
Thanks in advance for any help!
