Security

Your Tesla is as important to us as it is to you.

From account sign up to using Tessie out in the world, Tessie has paid close attention to guarding you and your Tesla.

No Passwords to Steal

Tessie doesn't use or store passwords, because they are easy to guess, steal and compromise from other websites.

Biometric Protection

Tessie supports a range of biometrics on iPhone, iPad and Android as an additional authentication factor.

Network Encryption

All inbound and outbound network connections are SSL/TLS 1.2 encrypted.

Remote Storage Encryption

All data is encrypted at rest using AES-256 and symmetric keys.

On-Device Data Protection

Tessie uses the dedicated Secure Enclave hardware layer on iPhone, iPad and Apple Watch, and the AES-encrypted Keystore on Android.

Access Control

Access to your Tesla can be revoked at any time by unlinking your Tesla account or by changing your Tesla password.

Multi-Factor Authentication Support

Tessie fully supports, and strongly encourages using, Tesla account multi-factor authentication.

Secure Account Linking

Tessie uses industry-standard OAuth authentication to ensure security. Here's how it works:

1. Sign in directly with Tesla

Tessie opens an SSL/TLS 1.2-encrypted window to tesla.com for you to sign in. These credentials are invisible to Tessie.

2. Tessie gets a random token

This token is used to communicate with your Tesla.

3. You control access

Revoke access by unlinking your Tesla account or by changing your Tesla password.
