Activating your Priority Pass benefit as an American Express cardholder in 2026 is a two-step digital process. First, you must log in to your AmEx online account or the AmEx app, navigate to the "Membership" or "Benefits" tab, and find the "Lounge Access" section to officially enroll in the program. Once enrolled, you will receive a confirmation, but you still need a separate account with Priority Pass. Go to prioritypass.com/activate and enter your unique 16-digit Priority Pass membership number (which is different from your AmEx card number) and the web PIN provided in your enrollment email. This will allow you to set up a username and password and access your Digital Membership Card via the Priority Pass app. Remember that your AmEx card itself is rarely accepted for entry at lounges; you must present either your physical or digital Priority Pass card to gain access.
