Privacy Risks of Digital IDs and Mobile Driver's Licenses

Mobile driver's licenses (mDLs) and digital IDs are rapidly moving from pilot programs into everyday use across the United States. While the convenience of tapping your phone instead of pulling out a physical card is appealing, these systems introduce new privacy risks that most people aren't aware of. Here's what you need to know before going digital with your identity.

The Current State of Digital IDs in 2026

As of 2026, mobile driver's licenses and government-backed digital ID wallets have moved from pilot programs into early production use in dozens of states. The TSA now accepts mobile driver's licenses at airport security checkpoints in participating states. Apple Wallet and Google Wallet both support mDLs, and several states have launched their own digital ID apps.

The push toward digital identity is accelerating. But the convenience comes with trade-offs that privacy advocates, civil liberties organizations, and security researchers have been raising alarms about.

How Mobile Driver's Licenses Work

A mobile driver's license stores your identity credentials on your smartphone, typically in a secure enclave (a hardware-protected area of the phone's processor). When you need to verify your identity — at an airport, a bar, or a traffic stop — you present your phone, which transmits the relevant information to a reader device.

The technology is built on the ISO/IEC 18013-5 standard, which is designed to enable selective disclosure — meaning you should be able to share only the specific data needed (for example, confirming you're over 21 without revealing your exact date of birth or home address).

The Promise of Selective Disclosure

In theory, mDLs are more privacy-preserving than physical IDs because you can share only the minimum information needed. A bouncer at a bar only needs to know you're over 21 — they don't need your home address, organ donor status, or license number. Selective disclosure makes this possible.

The Privacy Risks You Should Know About

1. Over-Collection of Data

While selective disclosure is technically possible, there's no guarantee that businesses will implement it correctly. Without strong laws mandating minimum data collection, a business could request — and receive — far more data than necessary. A liquor store verifying your age could potentially request and store your full name, address, date of birth, and license number.

2. Location and Transaction Tracking

Every time you use your mDL, a digital transaction is created. Depending on the implementation, this could create a detailed log of everywhere you've presented your ID — every bar, airport, pharmacy, and government office. This data trail doesn't exist with physical IDs.

3. Phone Compromise = Identity Compromise

If your phone is compromised by malware, a bad actor could potentially access your digital ID, especially if you don't have strong device security. While secure enclaves provide hardware-level protection, sophisticated attacks have breached these defenses before.

The Surveillance Concern

Privacy and civil liberties groups have warned that mobile IDs could facilitate government surveillance. Unlike a physical card in your wallet, a digital system creates auditable records of when and where you presented your identity. Without strict legal protections, this data could be accessed by law enforcement or other government agencies.

4. Fake App Scams

As digital IDs become mainstream, scammers are creating fraudulent ID apps designed to steal personal information. These fake apps mimic the look and feel of legitimate state-issued mDL apps, tricking users into entering sensitive information like Social Security numbers, dates of birth, and home addresses.

5. Inconsistent Standards and Protections

Because adoption varies by state, the protections around digital IDs are inconsistent. Some states have enacted legislation governing how mDL data can be collected and retained by third parties, while others have no specific protections in place. This patchwork means your privacy protections depend on where you live and where you use your digital ID.

6. Biometric Data Risks

Some digital ID systems incorporate facial recognition for identity verification, requiring you to take a selfie that's compared against your ID photo. This biometric data, if stored improperly or breached, creates permanent identity theft risks — you can change a password, but you can't change your face.

How to Protect Your Privacy With Digital IDs

If You Adopt a Mobile Driver's License

  • Use strong device security: Enable biometric authentication (Face ID, fingerprint) and a strong PIN on your phone. Enable remote wipe capabilities.
  • Only use official apps: Download your state's mDL app only from the official app store listing linked from your state DMV's website. Never download an ID app from a link in an email or text message.
  • Review what you're sharing: Before presenting your mDL, check exactly what data is being requested. If a business is requesting more than necessary, decline and use your physical ID instead.
  • Keep your physical ID: Don't abandon your physical driver's license. Keep it as a backup for situations where you don't want to create a digital transaction record.
  • Update your phone's software: Keep your phone's operating system up to date to ensure you have the latest security patches protecting the secure enclave.

If You're Concerned About Digital IDs

  • You can usually opt out: In most states, mDLs are currently optional. You are not required to adopt a digital ID and can continue using your physical driver's license.
  • Advocate for strong legislation: Support state and federal legislation that mandates data minimization, prohibits retention of mDL transaction data by businesses, and restricts government access to usage logs.
  • Monitor your personal data exposure: Digital IDs are just one piece of your overall privacy picture. Data brokers already hold extensive personal information about you that can be combined with mDL data.

Protect Your Identity Holistically

Your digital ID is only as secure as your overall digital footprint. If data brokers already have your home address, phone number, date of birth, and Social Security number exposed online, a digital ID adds another layer of risk. PrivacyOn removes your personal information from 100+ data broker sites and provides continuous monitoring to keep it removed, reducing the data available for identity theft and fraud.

The Bottom Line

Mobile driver's licenses and digital IDs offer real convenience, but they also introduce privacy risks that don't exist with physical IDs. The technology to protect privacy exists — selective disclosure, secure enclaves, data minimization — but whether those protections are actually implemented depends on state laws, business practices, and your own security habits. Stay informed, stay cautious, and keep your physical ID handy.
