mytesla.io — Tesla Fleet API Key Generation & Hosting

Generate Your Key Pair

mytesla.io generates Tesla Fleet API key pairs in your browser and hosts the public key on dedicated Azure Storage accounts with built-in HTTPS. It replaces FleetKey.cc, which Tesla blocked in May 2025. $14.99/year.

How It Works

Generate

Create an ECDSA P-256 key pair right in your browser. Free, instant, private.

Host

We host your public key on a dedicated Azure Storage account with built-in HTTPS. $14.99/year.

Register

Use your unique URL as the Allowed Origin in the Tesla Developer Portal. Done.

Why This Exists

Tesla requires every Fleet API developer to host a public key at a precise HTTPS URL. Most people don't have hosting infrastructure for a single PEM file.

FleetKey.cc is dead

The free community solution was blocked by Tesla in May 2025 for using a shared domain. Hundreds of thousands of Home Assistant users lost their key hosting overnight.

Dedicated = unblockable

Each user gets their own Azure Storage account with a unique *.web.core.windows.net URL. From Tesla's perspective, this is indistinguishable from you owning your own infrastructure.

HTTPS built in

Azure Storage static websites include Microsoft-managed SSL certificates. No custom domain, no Let's Encrypt, no configuration. It just works.

FAQ

What is this?

mytesla.io is a Tesla Fleet API key generation and hosting service. It generates ECDSA P-256 key pairs in your browser and hosts the public key on a dedicated Azure Storage account with HTTPS. Tesla requires this hosted key for Fleet API access. This replaces FleetKey.cc, which Tesla blocked in May 2025.

What happened to FleetKey.cc?

Tesla blocked FleetKey.cc in May 2025 because it used a shared domain to dynamically serve different keys for different users. Tesla detected this multi-tenant pattern and blocked the entire domain. mytesla.io solves this by giving each user a dedicated Azure Storage account with a unique URL.

Is my private key safe?

Yes. Your private key is generated entirely in your browser using industry-standard cryptographic libraries (the Web Crypto API). It never leaves your device. We never see it, store it, or transmit it. Only the public key is uploaded to your hosted storage account.

Does this work with Home Assistant?

Yes. This is the recommended replacement for FleetKey.cc for Home Assistant Tesla Fleet integration users. Generate your key pair, host the public key, then use the URL as your Allowed Origin in the Tesla Developer Portal. Follow the standard Home Assistant Tesla Fleet setup guide from there.

What if my subscription expires?

Your key stays accessible for 30 days after your subscription expires (grace period). After that, the URL returns an expired notice. After 90 days total, the storage account is deleted and the name is released. You can resubscribe at any time during the grace period to restore service instantly.

Can I regenerate my keys?

Yes. Log in to your dashboard at mytesla.io/manage, generate a new key pair, and click Regenerate Key. The new public key replaces the old one at the same URL. Note: you'll need to re-register the key with Tesla and re-pair your virtual key with your vehicles after regenerating.
