setting up ftp server

[hm786]

i followed a tutourial to create an ftp site, and then it asked me for a username and password, but i do not recall setting up any password in the tutourial, please can you help me out, possibly telling me if there is a default password? The link to the tutourial is :https://www.windowscentral.com/how-set-and-manage-ftp-server-windows-10

Many thanks.
