The access shared password is an optional password, that can be set by the Tenant or the Venue Manager for a Venue (the Tenant can also set this for all manageable Venues), and represents an additional access control for end-users, to be performed after authentication to the Splash Portal.
This can be applied to all sign-in methods supported by the Solution ("classical login", Social Login and Click-through mode). An end-user who does not enter the correct password, is not able to access the service, even if correctly performing the authentication on the Splash Portal.
The Tenant or the Venue Manager are able to change the password at any time, from the Control Panel, by editing Registration options.
A practical example
One of the possible scenarios of this solution is when you wish to give access to end-users by using a unique common password, and without asking them to remember individual access credentials (username/password).
This is only one example: the access shared password method indeed, as already said, can be applied over all sign-in methods supported by the Solution.
After that, the Splash Portal will ask the specified access password. The access to the Internet, of course, will be allowed only if the right password is entered, even if the "classic" authentication has been successful.
