# Login & Authentication

UltraClaw supports three ways to sign in. You must use the **same method you used when you registered** — if you signed up with your phone number, you log in with your phone number.

## Sign-In Methods

</CardGroup>

## Logging In

1. Go to [ultraclaw.ai](https://ultraclaw.ai) and click **Login**
2. Choose the method you used when you signed up
3. Complete the verification (SMS code, password, or Google OAuth)
4. You'll land on your [dashboard](https://ultraclaw.ai/dashboard)

<Warning>
  You must use the same sign-in method you registered with. If you try to log in with email but you registered with your phone number, it will not find your account.
</Warning>

## Linking Additional Sign-In Methods

Once logged in, you can link additional methods from your dashboard so you have multiple ways to access your account.

<Steps>
  <Step title="Open Account Settings">
    Go to [ultraclaw.ai/dashboard](https://ultraclaw.ai/dashboard) and navigate to **Account Settings**.
  </Step>

  <Step title="Link a method">
    Choose what you'd like to add:

    * **Link email** — if you signed up via phone or Google, add an email + password
    * **Link Google** — if you signed up via phone or email, connect your Google account
  </Step>

  <Step title="Verify and save">
    Complete the verification flow for the new method. Once linked, you can use any of your connected methods to log in.
  </Step>
</Steps>

## Troubleshooting

<AccordionGroup>
  <Accordion title="I can't log in">
    The most common cause is using a different sign-in method than you registered with. Try each method (phone, email, Google) to find the one you used at signup.
  </Accordion>

  <Accordion title="I didn't receive my SMS code">
    SMS codes can take up to 60 seconds. Check that you're using the exact phone number you registered with, including the country code. If you still don't receive it, try requesting a new code.
  </Accordion>

  <Accordion title="I forgot my password">
    On the login page, click **Forgot password** and enter your email address. You'll receive a reset link.
  </Accordion>

  <Accordion title="My Google account isn't working">
    Make sure you're signing in with the same Google account you used at registration. If you have multiple Google accounts, check that the correct one is selected.
