3Com 56K manual When using Autopass Prompting When using Password Prompting

Setting up Dial Security 10-5

Autopass Prompting Autopass is the default form of password protection. Autopass automates the process of logging in to the host modem, but it requires the guest and host devices to be Business Modems.

When a guest device attempts an Autopass connection, the guest includes its password in its V.42 error-control request. The host modem checks all the enabled passwords in its security accounts for a match.

Password Prompting Password Prompting allows connections with any guest device, as long as the guest user knows the correct password.

When the host has Password Prompting enabled, it asks guest users for a password. The host modem checks the received password against each of its active Security accounts.

The table below is a comparison between Autopass and Password prompting.
