## Account Questions

  </Accordion>

  <Accordion title="I forgot my username or password. What do I do?">
    Click **Forgot username or password?** on the sign-in page, or go directly to Capital One's [sign-in help page](https://verified.capitalone.com/sign-in-help/?client=SIC).
  </Accordion>

  <Accordion title="Can I activate someone else's card on their behalf?">

    Do not activate the card. Contact Capital One immediately by calling the fraud reporting line at **1-800-227-4825** (available 24/7) to report the situation. It's possible the card was sent in error or your identity may have been used without your permission. Capital One's fraud team will investigate and advise you on next steps.
