Patent attributes
A device that includes a secure element or a secure environment receives a token for authenticating a user that has an account with a service provider. The device generates, based on the token, a set of keys that include at least a private key and a public key. The device performs a key authentication procedure to compare the set of keys and a configured set of keys and selects a public key, of the set of keys or the configured set of keys, based on a result of the key authentication procedure. The device causes a device identifier of the device and the public key to be provided to another device that uses the device identifier and the public key to perform an authentication procedure to authenticate the user. The device receives, from the other device, an indication of whether the device is connected to a network.
