Auth for Tesla gets you a working Tesla API token in seconds — then helps you check it, prove it, and put it to work. Sign in once with your Tesla account and your refresh and access tokens are one tap from the clipboard, ready for Shortcuts, scripts, home-automation tools, or your own app. A TOKEN TOOL, NOT A CAR APP Auth for Tesla doesn't drive your car, wake it up, or try to replace the Tesla app. It does one job well: hand you a valid OAuth token and make it easy to use. ONE TAP TO COPY • Refresh token and access token side by side, each copied with a single tap. • A live "Valid for…" countdown on the access token, and a clear "Long-lived" badge on the refresh token. • Refresh both with one button — or with ⌘R on Mac. • Turn on token details for issuer, audiences, scopes, region, and expiry at a glance. YOUR PASSWORD STAYS WITH TESLA You sign in on Tesla's own website in a secure in-app browser. Your username and password never pass through this app or any developer-run server. Multi-factor sign-in works as usual, and sign-in survives a hop to your password manager. PROVE IT WORKS Test Your Token runs a few read-only calls against the Owners or Fleet API — your account, your vehicles, your scopes — so you know the token works end to end before you paste it anywhere. DEVELOPER TOOLS BUILT IN • JWT Inspector — paste any token, or pick a stored one, and see the decoded header, payload, scopes, expiry, and a clear Valid/Expired status. • Snippet Exporter — copy the active token as ready-to-run cURL, HTTPie, Swift, or Python, bearer header included. OWNERS API AND FLEET API • Owners API — the token most Tesla-compatible apps and Shortcuts ask for. • Fleet API — Tesla's official API for developers with a partner account, with the region (North America, Europe, Asia Pacific, Middle East, China) detected for you. EVERY ACCOUNT, ONE TAP APART Keep personal, work, and test accounts side by side for each API. Switch, rename, and add accounts without signing in again. SIRI & SHORTCUTS Get and Refresh actions for both APIs appear automatically in the Shortcuts app and work with Siri, and each can target a specific account. Build automations that always have a fresh token. IPHONE, IPAD AND MAC The same tools on every device, in a Liquid Glass design. PRIVATE BY DESIGN Tokens are stored encrypted in your iCloud Keychain and sync only across your own devices. No analytics, no tracking, no third-party SDKs.
