Security Best Practices with Cash App

Cash App Sign In

  • Every time you sign in to your Cash App account, you’re sent a one-time-use login code.
    • If you received an unsolicited sign in code via email, we recommend securing the email account associated with your Cash App account by updating your password and enabling two-factor authentication
  • If you sign in to your Cash App on a device other than your personal device, make sure to sign out.

Cash App Payment Verification

  • Enable the Security Lock setting so that every Cash App payment requires your passcode.
  • Enable notification via text message or email so that you are notified after every Cash payment. You may adjust these settings in the profile section of your Cash App.

Secure your mobile device

  • Create a passcode for your mobile device. To do so, check your device’s general settings. Because all devices vary, you may need to check your device manual for more information.

Secure your email

  • If you have an email address associated with your Cash App account, we recommend securing that email account by enabling two-factor authentication (if your email provider supports it).

Communication with the Cash Team
