A host which provides an FTP service may additionally provide Anonymous FTP access as well. Under this arrangement, users do not strictly need an account on the host. Instead the user typically enters 'anonymous' or 'ftp' when prompted for username. Although users are commonly asked to send their email address as their password, little to no verification is actually performed on the supplied data.
As modern FTP clients typically hide the anonymous login process from the user, the ftp client will supply dummy data as the password (since the user's email address may not be known to the application).
For example, the following ftp user agents specify the listed passwords for anonymous logins:
* Mozilla Firefox (2.0) — mozilla@example.com
* KDE Konqueror (3.5) — anonymous@
* wget (1.10.2) — -wget@
* lftp (3.4.4) — lftp@
The Gopher protocol has been suggested as an alternative to anonymous FTP, as well as Trivial File Transfer Protocol and File Service Protocol.
