Sshwifty is a SSH and Telnet connector made for the Web. It can be deployed on your computer or server to provide SSH and Telnet access interface for any compatible (standard) web browser. Sshwifty is a great free alternative to Shellngn. In this step by step guide I will show you how to install Sshwifty on your Synology NAS using Docker.

💡Note: This guide works perfectly with the latest Sshwifty 0.3.14 release.

Now open your browser and type in your HTTPS/SSL certificate like this https://ssh.yourname.synology.me In my case it’s https://ssh.mariushosting.synology.me at the top left click the + button. Follow the instructions in the image below.

Select Password as Authentication method. Select utf-8 as Encoding method. Click Connect. Follow the instructions in the image below.
