Change login password for SFTP Only ID

UNIX for Advanced & Expert Users
1

Hi All,

I have an SFTP server where there are user id's created for vendors and given only SFTP access for them (eg: given below)

jim.tran:x:10040:10008:abc.def@ghi.com:/dropbox:/bin/false

They cannot login to the server via SSH and can only do an SFTP. These users are set up as jailed users (chroot jail) and has a password which is expiring every 90 days. They might be using different tools to connect to the server like Core FTP, Filezilla, Putty sftp etc.

Question is how can these users change their password by themselves even before the passwords get expired ?

Thanks,
Sabari Nath S

They can't. You may have to set up some alternate system for them to do so.
