Ville Nahkuri shared these instructions on the Tesla Slack Community:
If you would like to add an additional user to your Tesla mobile app, with their own unique login details, you should first create a Tesla Account in their name. Then email us at [email protected] with the following information:
- Full VIN of the car
- First and last name of the user
- Their Tesla-registered email address
- Their phone number
- Their mailing address
The user will receive an email to validate their access. This can take up to 3-5 business days. Please keep in mind that this will grant the additional user access only to the Tesla mobile app, and allow them to monitor and control the vehicle.
You can find the intructions on the Tesla support site too.
