Possilble to access with SFTP aka with ssh-key file instead of user+password?

[Nam G VU]

I'm looking for FTP server that can serve with SFTP protocol using SSH key, is it possible? If yes, please guide us how to.

I have go thru the walkthru here and it seems to serve with user+password only.

Cheers

We may use atmoz/sftp at this ssh-login guide here

Pure-FTPd provides FTP & FTPS (FTP+SSL) support which works for most cases.
For SFTP support you'd need to use a dedicated SFTP service instead such as the one you mentioned :)
Hope this helps clarify.
