I set up a dedicated server with Ubuntu 16. I am using ssh to access it. I created access with key pairs. I wanted to use SFTP,my password was to simple so I changed the users' (not root) password on the server. However the new password did not work for the FTP . I tried my old password again and FileZilla connected to the server. Please note that on my server the password was changed (so I know that is not the issue)? What is going on, do I need to restart my server?
Some more information: I accessed the server with SFTP before I made the password change, so it worked with the old one but is still working with the old password...
Thank you.
