A month ago the firmware of ledger nano s+ has been elevated to 1.1.0. The most important thing (surprisingly for me not mentioned in the official release) brought to device by new firmware is the ability to install new app namely Security Key which implements Web Authn protocol and, thus, leverages public key cryptography security mechanism to fortify user's accounts opened on various WEB services. More on Web Authn and on the use of Security Key app can be read on dedicated page of
Ledger official blog.
