Integrate Log In with PayPal
Log In with PayPal (formerly PayPal Access) is a commerce identity solution that enables your customers to sign in to your web site quickly and securely by using their PayPal login credentials. Log In with PayPal is available free of charge.
Log In with PayPal provides an enhanced merchant experience for your customers through:
- Simplicity. Only one user identity to remember to log in.
- Convenience. Fewer address and bank account forms to fill out.
- Peace of mind. As always, PayPal secures customer financial information.
- Integration with seamless checkout. Customers can directly check out without logging in to PayPal again.

Customer, merchant, and developer benefits
Open, standards-based solutions
Log In with PayPal is based on OpenID Connect, which uses the open standard OpenID 2.0 and OAuth 2.0 protocols (OpenID Connect builds OAuth 2.0 capabilities into the protocol itself). This security enables you to trust that your users are securely logged-in. On your side, your system must manage the logged-in and log-out sessions. In addition, it must properly manage any of the user information provided through PayPal (specific user attributes can be shared by PayPal only after the user has provided consent to share those specific attributes with the merchant).
Streamlined sign up and sign in
Customers use their PayPal credentials to securely sign up and sign in to your site. This reduces cart abandonment, and can increase conversion rates and sales. Also, customers do not need to create a user account to shop and pay on your site.
Access to more customers
Better leverage PayPal's 100 million active members.
Automatic updates to customers' account data
Changes to user account data are dynamically updated.
To integrate Log In with PayPal, complete these one-time configuration steps.
Create your PayPal application
Follow the steps to create your PayPal application and enable Log In with PayPal for your application. If you are looking to combine your Log In with PayPal integration with your PayPal Express Checkout integration, enable the optional seamless checkout feature.
After you successfully create your PayPal application, store your
client_secret credentials and pass them to the PayPal endpoints in an authentication header in each request.
Embed the Log In with PayPal button
The Log In with PayPal button integration consists of these components:
- The Log In with PayPal button image that is displayed on the merchant's website.
- The authorization endpoint and the parameters passed to it. After customers click the button, they are forwarded to this endpoint.
- If you prefer to understand the inner workings of the button integration, you can choose to manually embed the standard Login with PayPal button and construct the authorization endpoint and its parameters.
The Log In with PayPal integration consists of three phases that take place each time a customer logs in with PayPal from the merchant's website:
The customer clicks on the Log In with PayPal button, which forwards the customer to the authorization endpoint.
If the customer successfully logs in to PayPal and consents to sharing basic information with the merchant, PayPal passes an authorization code to the merchant. The authorization endpoint is called from the Log In with PayPal button and the code is integrated into the button code. For integration information, see embed the Log In with PayPal button.
The merchant passes the authorization code received in the previous step to the tokenservice endpoint and receives an access token. For integration details, see grant token from authorization code. This access token expires after a short period of the time, so the merchant also receives a refresh token to periodically refresh the access token. For integration details, see grant token from refresh token.
The merchant obtains the user profile information that the customer has consented to share with the merchant by passing the access token received from the previous step to the userinfo endpoint. For integration details, see get user information.
Through the seamless checkout feature, a customer already logged in with PayPal to the merchant's website can choose to check out without logging in to PayPal again. For integration details, see Integrate Log In with PayPal seamless checkout.
