FileZilla Forums

Currently using WordPress on my live server that uses SFTP using an SSH key.

I'd like to install and upgrade plugins, but turns out you are required to enter your FTP login to install the plugins.

Is there a way to install and upgrade plugins by manually uploading the files instead of having WordPress handle the entire process?

In theory, yes. There are usually manual steps provided for installing plugins the old fashioned way. However, wouldn't that be a good question to them?

FileZilla can transfer (or, at least, attempt to transfer) everything to the server you instruct it to do. It does not care about what it is nor contents. We can't definitely answer your question, for that very reason.
