LEDGER Ledger Nano S USB hardware wallet（投稿ID : 1imr19）

The Ledger Nano S is a model with an OLED LCD screen. Not only for Bitcoin, but also for Ethereum. In this model, unlike the previous model, which required approval using a security card or smartphone app, approval can now be performed directly from the button on the device. This also eliminated the malware problem. Additionally, since it supports FIDO-compliant authentication methods, it can be used as is as a two-step authentication device in services such as Gmail, Dropbox, and Github.
