How can I manually edit existing IDs and Passwords?

Oh, this is interesting... And a Roboform user may have this question when using Sxipper for the first time.

It seems the only way to change either ID or Password is to go through an actual login on desired site and hope Sxipper remembers.

Separately, I just deleted a particular site with incorrect ID and Password and then went through the site's 2-step (separate pages) login. Sxipper simply will not remember the ID (1st page) but it does remember the password (2nd page).

Well, Sxipper doesn't like Roboform and you don't need to create a login item before using it. Just login to a website as usual and Sxipper will try to detect the information for you. So there's no way in design to let you manually edit those login IDs/passwords.

But in case, if you really want to take the risk of yourself, you can try to backup (export) the logins, manually add that file and restore is back to your browser.

The backup data file is actually a plain text file. Each line of the file has the following fields. Modify it when you clearly know the meaning of each field and take your own risk.

"hostname","username","password","formSubmitURL","httpRealm","usernameField","passwordField"

Good luck! ;)
