YubiKey Passwordless Login for Synology Devices


Note: In order to follow the steps in this guide, your Synology device must run DiskStation Manager (DSM) 7 or newer. If your device does not support DSM 7+, or you prefer to run an older version, you may still be able to use YubiKeys via authenticator app two-factor authentication. For general guidance on this, see Using Your YubiKey with Authenticator Codes, and for details specific to DSM, see this Synology article (under the section 2-Step Verification).

 

Configure Passwordless Sign-In

Note: This must be done for each account on your Synology device.
