# Setting up SMS or WhatsApp login

Privy enables your users to log in to their account via SMS or WhatsApp. Your account can be set up for **either** SMS or WhatsApp, but **not both** at the same time. Your chosen configuration will apply to all applications under your Privy account.

<Info>
  We recommend including alternative login options alongside SMS or enabling [Multi-Factor
  Authentication](/authentication/user-authentication/mfa) to ensure broad accessibility in regions
  without SMS coverage and to allow users to access their accounts in the event that they lose SMS
  access.

  <Accordion title="International SMS support">
    <Note>
      International SMS via BYO Twilio is available only for accounts on Scale and Enterprise plans.
      Reach out to [support@privy.io](mailto:support@privy.io) to request access.
    </Note>

    With your own Twilio account, you can configure geo-permissions for specific regions, implement custom fraud detection rules, set spending limits, and access comprehensive logging through Twilio's dashboard.

    1. You can [sign up for a Twilio account here](https://www.twilio.com/try-twilio), if you don't already have one. Ensure that your Twilio account is a paid account, fully onboarded, and fully verified.

    2. After you create an account, you'll have access to the Twilio Console, where you can configure a [Verify service](https://www.twilio.com/docs/verify) and [region coverage](https://www.twilio.com/docs/verify/preventing-toll-fraud/verify-geo-permissions).

    3. Reach out to us at [support@privy.io](mailto:support@privy.io) and provide the following Twilio credentials:

    * Privy app ID
    * Twilio Account SID
    * Twilio Auth token
    * Twilio Verify service SID

    <Note>
      Out-of-the-box international SMS is only available for accounts on Enterprise plans. Reach out to
      [support@privy.io](mailto:support@privy.io) to request access.
    </Note>

    <Warning>
      Privy uses Twilio to deliver international SMS, and underlying carrier costs are passed through to
      your account. Refer to [Twilio's pricing
      here](https://assets.cdn.prod.twilio.com/pricing-csv/SMSPricing.csv).
