⚡ 快速结论：
- 定价： Keeper Personal runs $1.79/mo. Proton Pass is free, then Pass Plus at $2.99/month.
- 最适合： Keeper Security for 商业 plans, privileged access and encrypted files. Proton Pass for a genuinely free 密码管理器.
- 主要区别： Keeper caps its free version at 10 records on one mobile device. Proton Pass free stores unlimited passwords on unlimited devices.
- 我们的选择： 守门员 安全, because FedRAMP authorisation, a security audit tool and zero trust architecture cover far more ground.
One of these tools was built for compliance officers.
The other was built to keep your inbox out of 数据 broker lists.
Keeper Security sells password management as part of a wider security stack.
Proton Pass sells privacy first and stores passwords along the way.
That split explains almost every difference below.

Keeper Security 的主要优势
Here is where Keeper earns its rating:
- Zero knowledge architecture: Encryption and decryption happen locally on your own device. Keeper can never read your data.
- Record-level encryption: Data is encrypted at both the device and record levels using AES-256. Elliptic Curve Cryptography adds a more efficient layer than traditional RSA.
- Security Audit tool: The dashboard flags weak passwords and reused entries automatically. You can fix the worst offenders in one sitting.
- Certification depth: Keeper is FedRAMP Authorized and holds SOC 2, ISO 27001 and PCI DSS. Few popular password managers carry that combination.
- Offline vault access: You can view and edit the encrypted vault without an internet connection. Handy on a plane or a bad 酒店 网络。
- One-Time Share and Emergency Access: Send a record with a time limit, or let a trusted contact reach the vault in an emergency.
- Hardware key support: Two factor authentication covers YubiKey, Google Titan, Duo Security and standard authenticator apps.

什么是质子传递？
Proton Pass is a free password manager from the maker of Proton Mail.
Proton AG owns Proton Pass and operates from Switzerland.
Proton Pass launched in 2023 as an open source password manager.
Its code is public and the German firm Cure53 has audited it.
One Proton account also unlocks Proton Calendar, Proton Drive and Proton VPN.
Every entry holds sensitive information that stays encrypted on your own device.
Runner Up: Proton Pass
Open source and end to end encrypted. The free plan covers unlimited devices and adds hide my email aliases.
Proton Pass Pricing
Proton Pass offers one free tier and three paid plans.
| 计划 | 价格 | 最适合 |
|---|---|---|
| 自由的 | €0/month | Unlimited logins, unlimited devices, 10 aliases |
| Pass Plus | 每月 2.99 欧元 | Dark web monitoring and vault sharing with 10 people |
| 帕斯家族 | 每月 4.99 欧元 | Up to six users with Pass Plus features each |
| 质子无限 | 每月 9.99 欧元 | All Proton services including Proton Mail and Proton VPN |
Pricing verified August 2026.
免费试用： None needed. Proton Pass free is free forever and no card is required.
退款保证： Paid plans carry a 30-day money-back guarantee if you cancel in time.
📌 笔记： Business buyers get separate tiers named Pass Essentials and Pass Professional. Proton Unlimited folds password management into the wider bundle of other Proton services.
⚠️ 定价说明： Proton Pass has no row in our source spreadsheet, so this table uses FahimAI’s verified figures. Paid plans here also cost more than NordPass and Bitwarden charge for similar security features.
Key Benefits of Proton Pass
Here is where Proton Pass pulls ahead:
- No device cap on free: You can store unlimited passwords across unlimited devices. Most rivals limit the free version somehow.
- Hide my email aliases: Generate a random address for each signup. Your personal email address never reaches the site.
- Integrated 2FA authenticator: Store and autofill TOTP codes without a separate authenticator app. The 2FA authenticator lives inside the vault.
- Pass Monitor: It flags weak passwords and reused entries. Dark web monitoring checks whether stored passwords have leaked.
- 质子哨兵： These advanced security features watch for suspicious logins on your Proton Pass account. Alerts arrive before damage spreads.
- Zero knowledge design: Encryption happens on your device, so only you can read the vault. Proton’s servers never hold your keys.
- Open code and audits: Anyone can inspect the source. Cure53 audits back the strong encryption claims.

Note: We have not logged extended hands-on time with Proton Pass yet. The points above come from Proton’s published documentation, its public audit reports and G2 reviews. Our full Proton Pass review covers the setup flow in more depth.

- No emergency access feature at the time of writing
- Thin compliance record next to enterprise-focused rivals
功能对比
Both tools keep your passwords safe behind audited encryption. The gaps show up once you look past the vault itself, so we lined up ten areas that decide most purchases.
| 特征 | 保管员安保 | 质子通道 |
|---|---|---|
| Starting price (paid) | 每月 1.79 美元 | 每月 2.99 美元 |
| Usable free plan | ❌ (10 records, one device) | ✅（无限） |
| 暗网监控 | ✅（付费插件） | ✅ (Pass Plus) |
| Hide my email aliases | ❌ | ✅ |
| Integrated 2FA authenticator | ❌ | ✅ |
| Encrypted file storage | ✅（附加组件） | ❌ |
| 特权访问管理 | ✅ | ❌ |
| 开源代码 | ❌ | ✅ |
| Offline vault access | ✅ | ❌ |
| 紧急通道 | ✅ | ❌ |
| 最适合 | Business plans and compliance | Privacy and a real free tier |
1. Password Storage and Free Plan Limits
守护者安全： Paid plans store unlimited passwords, payment cards and identity records. The free tier caps you at 10 records and works on one mobile device only. Upgrading to the premium version removes that ceiling straight away.
质子通道： The free plan lets you store unlimited passwords across unlimited devices. You also get ten aliases and unlimited logins without paying anything. Free users give up dark web monitoring and vault sharing, but nothing else.
⚠️ 警告： Treat the Keeper free tier as a demo. Ten records will not hold a real set of accounts online.
2. Encryption and Zero Knowledge Architecture
守护者安全： AES-256 encryption protects the vault, with Elliptic Curve Cryptography layered on top for efficiency. The zero knowledge architecture means encryption and decryption happen locally, so only you hold the keys. Keeper also runs a zero trust architecture where every connection is verified before access is granted.
质子通道： The same AES-256 standard secures every field with end to end encryption. Items stay end to end encrypted between devices, and Proton’s servers never see your keys. That design mirrors the secure communication model Proton built for Proton Mail.
3. Advanced Security Features and Monitoring
守护者安全： The Security Audit tool scores your vault and surfaces weak or reused entries on one board. BreachWatch scans breach dumps and warns you when stored passwords appear in a data breach. It is a paid add-on, so you pay extra for the monitoring most rivals bundle.
质子通道： Pass Monitor flags weak passwords and reused entries across the vault. Dark web monitoring on Pass Plus warns you when personal details surface. Proton Sentinel adds login alerts.
4. Two Factor Authentication
守护者安全： Two factor authentication covers 文本 messages, authenticator apps and hardware keys like YubiKey and Google Titan. Duo Security works as a second factor for teams already standardised on it. That breadth is why so many business customers land here.
质子通道： Multi factor authentication runs on time-based one-time passwords. The integrated 2FA authenticator stores those codes inside the vault itself, replacing a separate authenticator app. Hardware key options are thinner than what Keeper offers.
5. Password Generation and Autofill
守护者安全： Automated password generation creates strong entries whenever you sign up somewhere new. KeeperFill then fills usernames and passwords on any website or app. Autofill needs a right-click on each field, which is slower than the one-click approach elsewhere.
质子通道： 密码 发电机 builds either a memorable phrase or a random string. Autofill runs through the browser extension and mobile apps, and you just press the icon to fill login details. G2 reviews note it can be less consistent on complex forms.
6. Platform Coverage and Offline Access
守护者安全： Desktop apps cover Windows, Linux and there is a native macOS app alongside iOS and Android builds. Full offline access lets you read and edit the encrypted vault with no internet connection. That functionality is rare among popular password managers.
质子通道： The Proton Pass apps run on Windows, 苹果, Linux, iOS and Android. Desktop apps and a browser extension keep everything in sync. There is no offline editing mode.
7. Sharing, Secure Notes and File Storage
守护者安全： Records share securely between accounts, and One-Time Share hands someone time-limited access without an account. You can securely store secure notes and encrypted files, though storage is an add-on at $9.99 per year for 10GB. Emergency Access lets a nominated person reach the vault if something happens to you.
质子通道： Password sharing works through secure links, and Pass Plus shares a vault with up to ten recipients. Secure notes and file attachments sit in the same encrypted vault. There is no emergency access equivalent yet.
8. Business Plans and Privileged Access
守护者安全： This is the widest gap between the two. Keeper sells privileged access management designed to stop breaches before they spread, plus encrypted messaging and secure remote access. Admins get role controls, an audit log and compliance 报道 that satisfies SOC 2 and ISO 27001 reviewers.
质子通道： Business plans exist as Pass Essentials and Pass Professional with shared vaults and user provisioning. There is no privileged access tooling and no session management. For regulated industries there are better options on the Keeper side.
9. Transparency, Audits and Track Record
守护者安全： The code is closed, but third-party experts validate the platform through penetration testing and a public 漏洞 disclosure program. Keeper is FedRAMP Authorized and holds PCI DSS certification. Its security history is clean, with no major breach on record as of 2026.
质子通道： Anyone can read the source and check how Proton Pass works. Cure53 has audited the code independently, and Swiss privacy law governs the company. Formal compliance certifications are thinner than Keeper’s list.
💡 专业提示： Open code and formal certification answer different questions. Auditable source proves how the encryption works, while FedRAMP proves a company survives procurement review.
10. 定价与成本
Here is how the money lines up once you match the tiers.
| 层级 | 保管员安保 | 质子通道 |
|---|---|---|
| 自由的 | 10 records, one device | 免费：每月 0 美元 |
| Individual paid | Personal: $1.79/mo | Pass Plus: $2.99/month |
| 家庭 | Family: $3.83/mo | Pass Family: $4.99/month |
| Business / bundle | Business Starter: $7.00/mo | Proton Unlimited: $9.99/month |
守护者安全： Personal at $1.79/mo undercuts Pass Plus, and Family at $3.83/mo undercuts Pass Family. The catch is the add-ons: BreachWatch and file storage both carry an additional cost. Budget for those before you compare headline numbers.
质子通道： Nothing beats free, and the free tier here is a real product rather than a trial. Proton Unlimited at $9.99/month makes sense only if you want Proton Mail, Proton Drive and Proton VPN anyway. For just your passwords, the free plan may be enough.
不同场景
| 如果您需要…… | 选择 | 为什么 |
|---|---|---|
| A free plan on every device | 质子通道 | 完全没有设备数量限制 |
| Compliance paperwork | 保管员安保 | FedRAMP and SOC 2 certified |
| Email aliases without paying | 质子通道 | Ten aliases on the free tier |
| Encrypted file storage | 保管员安保 | Up to 100GB add-on available |
| Offline vault editing | 保管员安保 | Works with no connection |
| Auditable open code | 质子通道 | Cure53 reviewed the source |
💰 您的预算
Proton Pass wins outright if you refuse to spend anything, because its free tier is a real product. Keeper is cheaper once you are paying, but only until you add BreachWatch and storage.
🔌 您的技术栈
Already paying for Proton Mail or Proton VPN? Proton Unlimited absorbs password management with no extra line item.
🏢 您的公司规模
Solo users and families can go either way. Once an auditor asks where sensitive data lives, Keeper’s certifications answer the question faster.
🎓您的经验水平
Proton Pass is simpler on day one for anyone new to managing passwords. Keeper gives you more knobs, and the ability to ignore most of them.
🆓 免费试用和演示
Keeper gives you 30 days with no card upfront. Proton Pass needs no trial because the free plan never expires, so run both for a week on low-risk logins.
🛟 支持选项
Keeper runs 24/7 support for paying customers on every tier. Proton Pass lacks live chat support, so plan on tickets and documentation instead.

我们的评测没有涵盖的内容
This comparison focused on individuals, families and small teams. We did not deploy Keeper’s privileged access platform across an enterprise, or test Pass Essentials and Pass Professional at scale. Our notes reflect the August 2026 builds, so anything shipped after that date is missing here.

🏆 WINNER: KEEPER SECURITY
Keeper Security wins 4 out of 7 categories.
最适合： Regulated teams, families wanting encrypted files, anyone who needs offline access
These two products answer different questions. Keeper Security is a security company that happens to sell a vault, and the rating gap between 4.3 and 3.5 reflects how much more it does.
Offline editing, hardware keys, encrypted file storage and privileged access management have no equal on the Proton Pass side. The entry tier is also cheaper than Pass Plus.
We would still recommend Proton Pass in two cases. If you refuse to pay for a vault, Proton Pass free is the strongest option here. If you want your real address hidden behind aliases, nothing in the Keeper lineup matches it.
For everyone else, Keeper Security is the safer long-term home for your logins.
