Key:authentication

Some charging stations require authentication ("unlocking"), even if charging is for free. Different operators use different authentication mechanisms for their charging stations. Some charging stations 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 charging station is free or not, use fee=yes/no. For payment methods, use the payment=* key. To denote whether a charging station is public, or only accessible to a certain group, use access=*.
