# Passkeys & account recovery

## What is a passkey?

A passkey is a secure credential stored on your device and unlocked with Face ID, Touch ID, or your device PIN. Helios uses passkeys instead of passwords:

* There's no password that can be guessed, reused, or leaked.
* Signing in and approving sensitive actions both use your passkey.
* The key material never leaves your device.

## Keeping access safe

* **Keep your device's screen lock on.** Your passkey is protected by it.
* **Use your platform's passkey sync** (iCloud Keychain on Apple, Google Password Manager on Android) so your passkey is backed up and available on your other devices.
* **Don't share** approval prompts with anyone.

## If you lose access

If you lose your device or your passkey, Helios offers a few ways to recover your account:

* **Password manager** — Helios asks your password manager for your synced Helios passkey; you approve on your device.
* **Social recovery** — recover using a linked sign-in.
* **Email** — Helios sends a one-time code (OTP) to your email to verify it's you.

You'll be guided through whichever method fits your situation.

{% hint style="danger" %}
Helios will never ask you for your passkey, recovery codes, or approval prompts over email, chat, or phone. Anyone who does is trying to scam you.

## Frequently asked

### I got a new phone. How do I sign in?

If your passkey is synced through your platform (iCloud Keychain / Google Password Manager), it should already be available on your new device. If not, use one of the recovery methods above.

### Can I use Helios on more than one device?

Yes — if your passkey is synced through your password manager, you can use the same account across your devices.

### Can Helios reset my account for me?

Helios can't see or recreate your passkey. Recovery confirms it's really you through the methods above, then restores your access.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.helioscard.xyz/getting-started/passkeys-and-recovery.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
