A method for accessing communication networks includes receiving by a device an identification of a communication network; determining whether the identification corresponds to a registered communication network; if the identification corresponds to a registered communication network, generating a password for accessing the communication network by applying a cryptographic function parameterized with a secret value associated with the communication network to the identification; and automatically establishing a connection of the device to the communication network using the generated password. Furthermore, methods for managing access to communication networks and providing communication networks are disclosed. A corresponding client device, service infrastructure and service provider infrastructure are also detailed.
