Will Wallets Replace Passwords in the Era of Decentralized Identity

Passwords remain one of the weakest points in digital security today! Despite decades of use, they are increasingly ineffective in the face of modern internet threats — data breaches, phishing attacks, password reuse, and weak protections. In the age of Web3 and decentralized identity (DID), a new tool is emerging that could transform the landscape: the identity wallet — a digital wallet that manages your online identity.

If you’re new to decentralized identity, start with our article Crypto Wallet vs. Decentralized ID. Understanding DIDs. In this article, we explore how wallets built on decentralized identity systems and verifiable credentials could replace passwords entirely, transforming both security and usability across the web.

Why Passwords Are No Longer Enough

Passwords were never meant to be a long-term solution. Today, they:

  • Are vulnerable to breaches and phishing
  • Provide weak protection for sensitive ​​identity information
  • Are hard to manage for users
  • Rely on centralized identity systems that are increasingly distrusted

According to IBM and Verizon reports, over 80% of data breaches involve compromised credentials. That’s a call to action. 

The average user today manages around 35 online accounts, often with poor password hygiene. A recent global survey revealed that 25% of users reuse the same password across 11 to 20+ accounts, and 36% include publicly available personal data in their passwords, data often easily found via social media or forums. A clear example of the consequences came in December 2023, when the 23andMe breach exposed the data of nearly 7 million users after hackers exploited leaked passwords.

Users also often struggle with the cognitive burden of managing complex passwords and navigating multi-factor authentication processes, leading to security fatigue and potentially dangerous shortcuts.

What Is an Identity Wallet?

An identity wallet is a digital wallet that stores verifiable credentials, digitally signed pieces of information that prove identity. 

These can include:

  • A government-issued digital passport
  • A diploma or education certificate
  • Proof of age, address, or citizenship
  • Professional qualifications

With an identity wallet built on decentralized identity systems, users gain:

  • Have full control over your data
  • Share only the specific information required
  • Store data locally or in encrypted form
  • Authenticate without a password—using a digital signature or biometric scan

How Wallets Work in a Decentralized Identity System

A decentralized identity system combines several key components:

  • Decentralized Identifier (DID) – a user-controlled unique identifier
  • Verifiable Credential (VC) – a digitally signed record that validates a claim (e.g., age)
  • Decentralized ledger – a blockchain that anchors trusted issuers
  • Smart contracts – automate issuance and verification of credentials

When accessing a service, instead of entering an email and password, your identity wallet provides a verifiable claim (e.g., age 18+). The service validates this without ever accessing your private data.

Real-World Example: EU Digital Identity Wallet

digital identity wallet

The European Union is actively developing the EU Digital Identity Wallet, which allows citizens to:

  • Store ID cards, driver’s licenses, diplomas
  • Sign documents electronically
  • Access government services without a login or password

This initiative was launched by the European Commission in 2021 as part of the eIDAS 2.0 regulation. The goal is to make the wallet available to all EU citizens by 2026, recognized across all member states. The wallet will meet strict privacy standards, support mobile devices, and serve as a universal tool for authentication, document signing, qualification verification, and more.

It’s the first large-scale decentralized identity implementation at the national level, focusing on privacy, interoperability, and user control.

Government Approaches Around the World

Governments are approaching decentralized identity adoption in different ways, balancing innovation, trust, and regulation:

European Union (eIDAS 2.0) – Combines decentralized identity systems with legal trust services. The EU aims to roll out interoperable, privacy-focused Digital Identity Wallets (EUDI Wallets) by 2026. The eIDAS 2.0 framework blends self-sovereign identity (SSI) principles with legally recognized trust frameworks, involving qualified issuers and service providers. It emphasizes selective disclosure and legal validity across borders.

United States –  The U.S. ecosystem is market-driven and led by tech companies like Microsoft, IBM, and Oracle. It is innovation-focused with rapid adoption but lacks unified federal regulation, which results in challenges around standardization and interoperability.

Japan — Follows a hybrid approach that incorporates blockchain and decentralized identities as part of its digital transformation strategy. The government encourages adoption in healthcare, finance, and public services, focusing on security and standardization while maintaining flexible legal frameworks.

Wallets vs. Passwords: A Comparison

wallet vs password

Security. Passwords are prone to phishing and leaks, whereas identity wallets use cryptography and never expose your data to the service.

Convenience. Users no longer need to remember dozens of credentials—one wallet grants access to all platforms.

Privacy. Centralized systems collect and store your personal data; identity wallets let you decide what to share and with whom.

Control. Password systems are controlled by service providers. Wallets offer complete control to the user.

Scalability. Passwords struggle in multi-service ecosystems. Identity wallets work across platforms with high compatibility.

Who’s Already Using Identity Wallets?

1) Microsoft Entra Verified ID
A corporate platform by Microsoft for issuing and verifying verifiable credentials of employees, students, and clients. Built on open DID and VC standards, it integrates with enterprise systems and identity access management. Suitable for HR, education, public services, and B2B ecosystems.

2) Spruce ID
A Web3-native identity solution allowing users to sign in and approve actions using wallets instead of passwords. Popular in DAOs, DeFi, and NFT platforms.

3) Polygon ID
Built on zk-SNARK technology, this decentralized identity framework enables privacy-preserving verification of identity and user rights. It is designed for scalable Web3 applications within the Polygon ecosystem.

4) Dock, Disco, ION (Bitcoin)
These projects build infrastructure and standards for verifiable credentials and DID:

Who Will Ditch Passwords First?

Web3 projects – Already pioneering the shift to decentralized identity. Most decentralized apps now support wallet login and DID. It’s a natural evolution based on self-sovereign identity.

Fintech startups – within 1–3 years. Seeking to streamline KYC via identity verification using wallets. These companies aim to reduce KYC costs and boost security. Identity wallets automate onboarding and cut fraud risk.

EU public services – Mandated to adopt decentralized identities by 2026. eIDAS 2.0 mandates member states to adopt digital identity wallets. Citizens will use them to access state services.

Education and HR – within 3–5 years. Diplomas, certificates, and experience can be shared as verifiable credentials. This will streamline job applications and background checks.

Traditional SaaS – Slower adoption due to reliance on centralized identity models. Most legacy SaaS rely on LDAP, SSO, or centralized login systems. Migration will require architectural shifts and clear user demand.

How Wallets Enable Passwordless Login

  1. The service asks for proof of identity.
  2. The user selects a credential in their wallet (e.g., proof of email).
  3. The wallet signs the request and sends it to the service.
  4. The service verifies the signature via the decentralized ledger.
  5. Login complete—without username, password, or email.

This is known as passwordless login and is already being implemented across Web3 apps, financial platforms, and government systems.

Technical Breakdown of an Identity Wallet

An identity wallet isn’t just an app, it’s a secure architecture for managing identity:

  • Storage – encrypted local/cloud storage of VCs
  • Signature – generates cryptographic proofs for login and verification
  • DID management – create/manage decentralized identifiers
  • Interface – visual and programmatic APIs (DIDComm, OpenID for VC)

Robust wallets support:

  • Biometric unlock (FaceID, TouchID)
  • Recovery options (social recovery, multi-party computation)
  • Secure enclaves (hardware-based protection)

How DID and VC-Based Login Works — Step by Step

  1. A site or service sends a challenge (“Prove who you are”)
  2. The user selects a credential in their wallet (e.g., “I am over 18”)
  3. The wallet signs the challenge and credential
  4. The service verifies the cryptographic signature
  5. Access granted without exposing personal data
