Once I’ve enabled the PayPal Security Key, how do I use it with my mobile phone?

There are two ways to connect to the PayPal Security Key via a mobile phone:

1. Log in to PayPal.com via your mobile phone

Here's how to get the security code sent to your phone:
  • When you log in, click the Send SMS button and check your mobile phone for the text message with a 6-digit security code. You'll usually receive a text message response in less than a minute, depending on your carrier service.
  • If you have multiple phone numbers on your account, be sure your mobile phone has been set as the primary phone number. If SMS is not available, we can also call your primary phone number if you’d like to listen for your 6-digit security code.
  • Make sure that your primary mobile phone number is enabled before you enable the Security Key, or else you won’t be able to log in with the Security Key. Note: you can still log in via a different method (for example, by answering your account security questions).
There is no fee to use the PayPal Security Key, however your standard mobile rates apply when you receive a security code by SMS or by phone. Check with your mobile provider for details.

2. Download and launch the PayPal app

If you’re using the PayPal app on your mobile phone instead of logging in through our website on your phone:
  • Log in to your account with your email and password, as you normally do, and wait for a PayPal Security Key SMS that will contain your OTP. Enter your pin to log in.
  • The PayPal app allows you to log in to you account using your iOS/Android device’s fingerprint reader. Check the app settings to set up this feature.
If you requested a code but did not receive one, first ensure your device has proper reception. Note that if you are in an area without a phone signal or with a period of high network traffic, the token might not arrive in a timely manner. You can request another code by tapping Send SMS again.
