Great post THX !!!
Kudo's & what else...
The used IP address is here the IP address of the Jolla smartphone in your local wlan.
You can get your IP address o your smartphone via settings > system settings > developer mode > WLAN IP address.
To sum up:
1.) Activate developer mode (settings > systems settings > developer mode)
2.) Enable remote connection and set an SSH password
3.) Change the password of the nemo account, via terminal
You have to enter the password you set as your SSH password (see 2.)).
Here you have to set a new password for user nemo.
4.) Connect your Jolla to your WLAN, if not connected already
5.) Check your WLAN IP address (settings > system settings > developer mode > WLAN IP address)
6.) Connect to the sftp server of your smartphone, by using the IP address and nemo as user, for example with Dolphin. You have to authenticate by using the passwd you set for your nemo user (see 3.)).
