Auth for Tesla is the fastest way to get a working Tesla API token — and the easiest place to inspect, test, and reuse it. Sign in once with your Tesla account, and your access and refresh tokens are ready to copy into Shortcuts, third-party tools, scripts, or anything else that talks to Tesla's API. A TOKEN TOOL, NOT A TESLA CLIENT Auth for Tesla doesn't drive your car, drain your battery, or pretend to be the Tesla app. It does one job extremely well: hand you a valid OAuth token and help you make sure it works. BOTH TESLA APIS • Owners API (v3) — the standard token used by most Tesla-compatible apps and Shortcuts. • Fleet API (v4) — Tesla's modern, officially supported API for developers with a partner account. MULTIPLE ACCOUNTS Keep personal, work, and test accounts side by side. Switch between them with one tap, rename them, and add new ones without losing the others. 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. No more flipping to jwt.io. • Snippet Exporter — generate ready-to-paste cURL, HTTPie, Swift, or Python snippets for the active token, complete with bearer header. • Test Your Token — run a few read-only diagnostic calls against the Tesla API to confirm your token actually works end to end, plus a local scopes inspection. TOKEN HEALTH AT A GLANCE Every profile shows a live countdown to expiry, the time of the last successful refresh, and the detected region (NA, EU, AP, ME, CN) so you always know what you're talking to. SIRI & SHORTCUTS All four token actions — Get and Refresh for both Owners and Fleet API — appear automatically in the Shortcuts app and work hands-free with Siri. Build automations that always have a fresh token. PRIVATE BY DESIGN Your Tesla username and password are entered directly in a secure in-app browser — they never pass through this app or any developer-run server. Tokens are stored encrypted in your iCloud Keychain and sync privately across your own devices. No analytics, no tracking, no third-party SDKs.
