By default, password authentication is
enabled for VTY lines.
In VTY line view, this command is
associated with the protocol inbound
command. If you specify a non-default
value for only one of the two commands in
VTY line view, the other command uses the
default setting, regardless of the setting in
VTY line class view.
Remarks

Changing this setting does not affect online
users. If the current number of online Telnet users
is equal to or greater than the new setting, no
additional Telnet users can log in until online
users log out.
