# Magic Link Login

> Passwordless authentication for the 0xRadar dashboard and API.

Magic links let you sign in to the 0xRadar dashboard without a password. An email containing a one-time link is sent to your inbox — clicking it authenticates you instantly.

## How it works

<Steps>
  <Step title="Enter your email">
    Go to [0xradar.app](https://0xradar.app) and enter your email address in the login form. Click **Send Magic Link**.
  </Step>

  <Step title="Check your inbox">
    An email from `noreply@0xradar.app` arrives within seconds. Click **Sign In to 0xRadar** inside the email.
  </Step>

  <Step title="You're in">
    The link opens the dashboard and logs you in automatically. Your API key is visible under **Settings → API Keys**.
  </Step>
</Steps>

<Note>
  The magic link is **single-use** and expires after **15 minutes**. If it expires, return to the login page and request a new one.
</Note>

## Rate limits

To prevent abuse, magic link requests are rate-limited to **3 requests per 15 minutes** per email address. If you hit the limit, wait before requesting again.

## Alternative: API key login

If you have an existing API key and prefer direct access, you can authenticate programmatically without going through the dashboard:

```bash theme={null}
# Step 1 — request a magic link
curl -X POST https://api.0xradar.app/v1/auth/magic-link \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com"}'

# Step 2 — verify the token from the email link
curl -X POST https://api.0xradar.app/v1/auth/verify \
  -H "Content-Type: application/json" \
  -d '{"token": "mlnk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"}'
```

A successful `/v1/auth/verify` call returns a session token and your API key:

```json theme={null}
{
  "session_token": "sess_xxxxxxxxxxxxxxxx",
  "api_key": "0xr_pro_YOUR_KEY_HERE",
  "expires_at": "2026-05-28T09:30:00.000000"
}
```

## Troubleshooting

<AccordionGroup>
  <Accordion title="I didn't receive the email">
    Check your spam or junk folder. The sender is `noreply@0xradar.app`. If it's not there after 2 minutes, try requesting a new link from the login page.
  </Accordion>

  <Accordion title="The link says 'already used' or 'expired'">
    Magic links are single-use and expire after 15 minutes. Go back to the login page and request a fresh link.
  </Accordion>

  <Accordion title="I hit the rate limit">
    Wait 15 minutes from the time of your first request, then try again.
