How do I set up my PayPal powered by Braintree account to allow Log In with PayPal?
If you already have an established PayPal account, you can choose to use your PayPal username and password to log into the Braintree sandbox or production environments. While this does not link your PayPal and Braintree accounts in any way, it does allow you the convenience of using only one set of login credentials for two separate accounts.
Enabling Log In with PayPal does not automatically set up your Braintree account to accept PayPal as a payment method. If you would like to accept PayPal via the Braintree gateway, you willl need to configure PayPal separately.
