The invention relates to a computer-implemented method for connecting a vehicle to a wireless local network of a workshop, comprising: identifying at least one wireless local network configuration of the wireless local network, said wireless local network configuration being associated with credentials for using said wireless local network, associating at least one validity parameter to said credentials in order to allow limited accessibility for the vehicle to said wireless local network, generating an encrypted visual representation of said credentials, thereby enabling the generated encrypted visual representation to be presented to a camera of the vehicle and decrypted to obtain said credentials, upon receipt of a connection request including the credentials from the vehicle, checking the at least one validity parameter to determine that the credentials are still valid for the vehicle, upon determination that the credentials are still valid, allowing the vehicle to connect to the wireless local network of the workshop.
