RE: [EN] U2F - Universal Second Factor - The basic functionality
Great thanks for this detailed explanation about U2F. I use a Nano Ledger as a cold storage but without the U2F option because I was thinking that a hardwarewallet by itself is pretty secure enough. So do you think that U2F should be always used even with Nano Ledger or is it just mandatory for those who need some kind of extra potection?
Thank you very much!
If you use the ledger as cold storage, this is a secure way to secure your coins.
U2F is an easy way to implement a factor in authentication processes. This is not necessarily necessary.
However, it is important to use 2 factors of authentication in any way.
