taginfo: authentication:*

This page describes a key prefix rather than a simple key.

Some facilities require authentication ("unlocking"), even if the use is for free. Different operators use different authentication mechanisms for their facilities. Some facilities even support several authentication mechanisms, and the user can choose which to use.

Authentication vs payment

This key is only concerned with the authentication method, not the payment method. If you can pay directly without having to register or be part of a network, then use authentication:none=yes.

To denote whether a facility is free or not, use fee=yes/no. For payment methods, use the payment:*=* key. To denote whether a facility is public, or only accessible to a certain group, use access=*.

Use of authentication on parking lots

authentication:*=* is also used in combination with parking lots and street parking. It describes what needs to be done to park legally. The two common subkeys are

• authentication:disc=* - a parking disc needs to be displayed to show the time of arrival
• authentication:ticket=* - a ticket needs to be bought and displayed in the car.

See Street_parking for details.
