In a world where data breaches happen almost daily, one question keeps coming up among security-conscious users: what password manager has never been hacked? With cybercriminals becoming more sophisticated, choosing a password manager is no longer just about convenience—it’s about trust, architecture, and proven security history.
This in-depth guide examines the password managers that have never experienced a known data breach, explains what “never been hacked” truly means, and shows you how to choose the safest password manager for your needs in 2025 and beyond.
Why Password Managers Matter More Than Ever
Most people still reuse passwords across multiple websites. According to security research, reused credentials are responsible for over 80% of account takeovers. A password manager solves this by generating, storing, and autofilling strong, unique passwords for every service you use.
However, if the password manager itself is compromised, the consequences can be catastrophic. That’s why many users ask: Has this password manager ever been hacked?
What Does “Never Been Hacked” Actually Mean?
No software system is 100% immune to attacks. When people say a password manager has “never been hacked,” they usually mean:
- No known breach exposing user password vaults
- No leaked master passwords or encryption keys
- No plaintext user data stolen
- Strong encryption prevented attackers from accessing vault contents
Some companies have suffered incidents but protected user data due to zero-knowledge encryption. Others have a completely clean public security record.
Password Managers That Have Never Been Hacked
After analyzing public disclosures, security audits, and vulnerability databases, the following password managers have no publicly reported breaches exposing user vault data as of 2025.
| Password Manager | Security Model | Independent Audits | Known Breaches | Best For |
|---|---|---|---|---|
| Bitwarden | Zero-knowledge, open-source | Yes (3rd-party audits) | None | Power users & teams |
| 1Password | Zero-knowledge + Secret Key | Yes | None (vault data) | Families & businesses |
| KeePass | Local encryption | Community reviewed | None | Offline users |
| Proton Pass | End-to-end encryption | Yes | None | Privacy-focused users |
1. Bitwarden: Open-Source Transparency and Zero-Knowledge Security
Bitwarden is widely regarded as one of the most trustworthy password managers available today. Its biggest advantage is transparency—its source code is publicly available for anyone to audit.
Bitwarden uses:
- AES-256 bit encryption
- Zero-knowledge architecture
- PBKDF2 and Argon2 key derivation
- Optional self-hosting
Even if Bitwarden’s servers were compromised, attackers would not be able to read user vaults without the master password, which Bitwarden never stores.
Security record: Bitwarden has never suffered a known breach exposing encrypted vault data.
2. 1Password: Extra Protection with a Secret Key
1Password takes a unique approach by combining your master password with a locally generated Secret Key. This means that even if someone stole 1Password’s servers, they still couldn’t decrypt user vaults.
Key security features include:
- AES-256 encryption
- Zero-knowledge design
- Secret Key stored only on user devices
- Regular third-party security audits
While 1Password has reported minor security incidents in the past, no customer vault data has ever been compromised.
3. KeePass: A Password Manager That Lives Offline
KeePass is an open-source, offline password manager. Unlike cloud-based services, your password database stays entirely on your device.
This eliminates server-side attacks altogether. However, security depends heavily on how well you protect your local system.
Security record: KeePass itself has never been hacked. Vulnerabilities typically come from third-party plugins or poor user practices.
4. Proton Pass: Built by Privacy Experts
Proton Pass is developed by the same team behind Proton Mail and Proton VPN. It uses end-to-end encryption and a strict zero-access policy.
All encryption keys are generated and stored on user devices, meaning Proton cannot see or recover your passwords.
Security record: No known breaches affecting user password vaults.
Password Managers That Have Been Hacked (But Data Stayed Safe)
Some popular password managers have experienced security incidents, yet strong encryption prevented attackers from accessing passwords.
- LastPass: Multiple breaches reported; encrypted vaults were accessed but not decrypted
- Dashlane: No major vault breach, but has disclosed minor vulnerabilities
These cases show why encryption architecture matters more than marketing claims.
How to Choose the Safest Password Manager for You
When choosing a password manager, focus on these critical factors:
- Zero-knowledge encryption
- Independent security audits
- Open-source code (where possible)
- Strong key derivation methods
- Multi-factor authentication support
If you run a tech business or manage sensitive systems—like online platforms or payment services—this decision becomes even more critical. (You may also want to read our guide on how to protect your online accounts from hackers.)
Key Takeaways
- No password manager can guarantee zero attacks, but some have never lost user data
- Bitwarden, 1Password, KeePass, and Proton Pass have clean security records
- Zero-knowledge encryption is essential
- Open-source software allows public verification
- User habits matter just as much as software security
Frequently Asked Questions (FAQs)
Is there a password manager that is 100% hack-proof?
No system is completely hack-proof. However, strong encryption ensures that even if a breach occurs, your data remains unreadable.
Is Bitwarden safer than LastPass?
Many security experts prefer Bitwarden due to its open-source code, clean breach history, and transparent security audits.
Should I trust cloud-based password managers?
Yes if they use zero-knowledge encryption. In many cases, cloud password managers are safer than storing passwords manually.
What happens if I forget my master password?
With zero-knowledge systems, recovery is often impossible. This is a security feature, not a flaw. Always store recovery keys securely.
Final Verdict: What Password Manager Has Never Been Hacked?
If your priority is a password manager with a spotless security history, Bitwarden, 1Password, KeePass, and Proton Pass are currently among the safest choices available.
The real question is not just which password manager has never been hacked but which one would still protect your data if a breach ever happened.
