A passport-based digital ID is a digital identity credential created from verified information in a physical passport. In the United States, current wallet implementations can read information from an authentic U.S. passport, confirm the electronic passport data, verify that the person enrolling matches the passport holder, and then provision a separate digital credential to a supported device.
Short answer: your physical U.S. passport acts as the trusted source document. The phone reads the passport’s data page and electronic chip, the service checks that information and verifies the holder, and an independent digital credential is created for later identity presentation. The digital credential is not a photo of the passport and does not turn the phone into a replacement passport.
What a U.S. Passport-Based Digital ID Actually Is
The term can be confusing because a modern U.S. passport is already an electronic passport, or ePassport, with a chip inside the physical booklet. A passport-based digital ID is something different: it is a new digital credential created from information verified through that passport.
The physical passport remains the original government-issued document. The passport-derived credential is provisioned to a phone or another supported device after the enrollment service confirms the passport and the person presenting it.
Current U.S. examples illustrate the concept. Apple allows eligible users to create a Digital ID in Apple Wallet from an authentic, unexpired U.S. passport. Google Wallet allows an ID pass to be created from a supported passport, including a U.S. passport. The two products have their own enrollment, device and acceptance rules, so “passport digital ID” should not be treated as the name of one universal credential.12
Passport-based does not mean government-issued digital passport. The physical passport supplies trusted identity information, but the resulting wallet credential is a separate digital object with its own issuer, rules and accepted uses.
The Trust Starts With the Physical Passport
The process works because an ePassport contains more than printed information. Its contactless chip stores identity data and a digital security feature that can be checked for authenticity and integrity. ICAO describes ePassport validation as verifying the digital signature on the chip to determine whether the electronic data came from the proper issuing authority and whether it has been altered.3
During enrollment, a wallet may first scan the The standardized machine-readable characters on a passport data page that allow passport information to be read electronically. on the passport’s data page. The phone can then communicate with the The contactless electronic chip embedded in an electronic passport and used to store digitally protected passport data..
This matters because copying the printed name, passport number and photograph would not provide the same evidence as working with authenticated electronic passport data. The chip includes digitally protected information tied to the passport’s issuance, allowing compatible systems to perform checks that cannot be performed from a photograph or screenshot alone.
How a Passport Becomes a Digital Identity Credential
The exact screens and technical checks differ by wallet, but present U.S. implementations follow the same broad model: inspect the source passport, validate its electronic information, confirm the person enrolling is the passport holder, and provision a new credential.
- The physical passport is scanned. The enrollment process reads information from the passport data page rather than asking the user to type every identity field manually.
- The electronic chip is read. A compatible phone communicates with the passport’s contactless chip to obtain electronically stored passport information.
- The passport information is validated. The service checks the passport data as part of determining whether the document being used for enrollment is authentic and acceptable.
- The person is matched to the passport. Current wallet systems require a live facial verification step rather than relying only on possession of the document.
- A separate digital credential is provisioned. Once the required checks are completed, the digital ID or ID pass is added to the supported wallet or device.
For example, Apple’s Digital ID enrollment uses the passport’s MRZ and ePassport data and requires the user to provide a Live Photo. Apple states that, for its Digital ID, this information is sent to Apple as the issuing authority for the Digital ID rather than to a state or national government.4
Google’s ID pass enrollment similarly requires the user to scan the passport information page, scan the passport security chip and record a facial video for identity verification. Google states that an ID pass is encrypted and stored on the device rather than in the user’s Google Account.5

The Digital Credential Is Derived From the Passport, Not a Copy of It
A passport-based digital ID should not be understood as a scanned passport stored in a wallet app. A scan or photograph reproduces what the document looks like. A digital credential is created only after an enrollment system has processed and verified information associated with the source passport.
The distinction also separates the source document from the derived credential. The U.S. passport continues to exist as the physical document issued for its established passport functions. The digital credential has its own lifecycle and can be accepted only by systems that support that particular type of digital identity presentation.
A successful passport scan does not place the passport itself inside the phone. It provides verified source information used to create another credential.
What Happens When the Digital ID Is Presented
Enrollment and presentation are separate events. Enrollment establishes the digital credential on the device. Presentation occurs later, when a compatible verifier asks the holder to provide identity information.
The holder is shown the request and authenticates on the device before the credential is presented. The verifier then evaluates the digital response rather than deciding whether an image displayed on the phone looks genuine. The exact communication method and information requested depend on the wallet, credential and verification system.
This also means that possessing a passport-based digital ID does not make it usable everywhere. The business, agency, website or checkpoint on the other side must support the relevant credential and presentation method.
Acceptance remains limited and provider-specific. Apple’s current documentation says its passport-derived Digital ID can be used at select TSA checkpoints in the United States for domestic identity verification and cannot replace a physical passport for international travel or border crossing. Google likewise states that its ID pass is not a replacement for physical documentation and may not be universally accepted.67
Why Passport Verification and Digital ID Verification Are Two Different Checks
There are two trust decisions in the overall process. First, the enrollment system has to establish confidence in the physical passport and the person using it. Later, a verifier has to establish confidence in the digital credential presented from the device.
The first stage reaches back to the passport as the source of identity information. The second deals with the credential that was created from that verified source. This separation is what allows a person to present a digital identity credential later without rescanning the physical passport for every supported transaction.
It also explains why passport-based digital ID does not depend on showing a visual passport page on a screen. The useful part of the system is the verifiable digital relationship between the source passport, the enrolled holder, the issued digital credential and a verifier capable of recognizing it.
A U.S. passport-based digital ID is best understood as a derived identity credential: the passport establishes the source identity, enrollment binds that identity to the holder and device, and the resulting credential can then be presented where compatible verification is available.
