One Proton account also opens Proton Calendar and the other Proton services.
Signup takes about a minute, and Proton Pass free needs no payment details.

Key Benefits of Proton Pass

- Integrated 2FA authenticator: TOTP codes live beside each login. No separate authenticator app is needed.
- プロトンセンチネル: These advanced security features watch for suspicious sign-ins on your Proton Pass account.

機能比較
Both tools guard the same thing. They just build very different walls around it.
We compared ten areas that decide which vault fits your work. Start with the summary, then read the detail below.

| 最適な用途 | Families and business teams | Privacy-first individuals |
1. セキュリティアーキテクチャと暗号化
ラストパス: Encryption happens on your device, so LastPass never sees your master password. That model held up in 2022, when attackers copied encrypted vault backups from LastPass servers. Weak master passwords were the exposure, which is why LastPass security now enforces a longer minimum.
プロトンパス： AES-256 strong encryption protects every entry of sensitive data, and items stay end to end encrypted on Proton’s servers. The zero knowledge design means only you hold the keys. Cure53 audited the code, and anyone can read it.
⚠️ 警告： No vendor can rescue a weak master password. Pick a long passphrase before you move a single entry.
2. Vault and Password Management
ラストパス: The vault holds logins, secure notes, cards, and addresses in named folders. LastPass features also include 1GB of encrypted file storage for documents. Password management stays organised even past a thousand records.
プロトンパス： It stores more than just your passwords, covering cards, aliases, and secure notes. Recent builds added file attachments, so sensitive information can be stored securely beside a login. Existing passwords import as JSON, CSV, ZIP, or XML.
3. Plans, Devices and Free Version Limits
ラストパス: Five paid tiers run from Premium up to Business MAX. LastPass Teams, LastPass Families, and LastPass Business each add seats and admin tooling. The catch sits on the free tier, where the free version limits users to one device type.
プロトンパス： Free users store unlimited passwords on unlimited devices with no seat cap. That free plan is the strongest in this category. Paid plans then layer on aliases, sharing, and monitoring.
4. パスワードジェネレーター
ラストパス: パスワード ジェネレータ builds a secure password of any length from the extension or the app. Every new entry saves straight into the vault. It is the fastest route to unique credentials on every site.
プロトンパス： Password generation offers random strings or memorable phrases, depending on what you have to type by hand. Both formats meet the same strength targets. Proton Pass offers the choice at signup time, not buried in settings.
5. Multi Factor Authentication
ラストパス: Multifactor authentication covers hardware keys, biometrics, and the LastPass Authenticator with push approval. Business tiers extend multi factor authentication policies across staff accounts. The codes live in a separate app rather than the vault.
プロトンパス： An integrated 2FA authenticator sits inside the vault itself. Two factor authentication codes appear next to the matching login, so you copy nothing between apps. Proton Sentinel adds sign-in monitoring on top.
6. Dark Web Monitoring and Email Aliases
ラストパス: Dark web monitoring watches breach dumps for addresses tied to your account. Alerts arrive in the security dashboard when a match surfaces. There is no aliasing layer, so your real address still lands on every signup form.
プロトンパス： Hide my email aliases generate a throwaway address per site, which is why reviewers recommend Proton Pass for personal privacy. Ten aliases come free, and Pass Plus removes the cap. Pass Monitor then flags exposures on the dark web.
7. Passwordless Login and Vault Access
ラストパス: Passwordless login opens the パスワードボールト with a fingerprint or a push from the LastPass mobile app. You still keep a master password for recovery. Emergency access lets a nominated contact reach the vault after a waiting period.
プロトンパス： Biometrics unlock the desktop apps and mobile builds, and passkey support is built in. There is no handover feature for a trusted contact. That gap matters more than most buyers expect.
8. Save, Autofill and Browser Extensions
ラストパス: The LastPass extension saves and autofills across Chrome, Firefox, Edge, and Safari. Support for Internet Explorer was retired years ago. Browser extensions carry most of the daily workload here.
プロトンパス： A browser extension handles autofill so you can securely log in anywhere. Since Proton Pass launched, the Proton Pass apps have spread to Windows, Mac, Linux, iOS, and Android. Nothing is browser-only.
9. Password Sharing and User Management
ラストパス: Password sharing runs through shared folders with per-person permissions. Admin access management on Business tiers covers provisioning, revocation, and reporting on employee access. User management is the clearest advantage LastPass holds.
プロトンパス： Sharing works through secure links or vault invites, and Pass Plus covers up to ten recipients. Everything stays encrypted in transit. Admin layers are lighter than a business buyer usually expects, which keeps managing passwords simple but limits control.
10. Password Hygiene and Reminders
ラストパス: The LastPass security dashboard scores every entry and surfaces reused or weak passwords. Password reminders nudge you when an entry ages past a safe window. That feedback loop builds good password hygiene faster than any lecture.
プロトンパス： Pass Monitor scores stored passwords and warns on reuse. It also checks whether login credentials have appeared in a data breach. Reporting stops at the individual, with nothing for staff auditing.
💡 プロのヒント: Fix every reused entry before you migrate. Carrying weak credentials into a different password manager solves nothing.
11. 価格設定とコスト
Here are the paid plans side by side.
| ティア | ラストパス | プロトンパス |
|---|---|---|
| 無料 | One device type only | $0, free forever |
| 入場料支払い済み | Premium, $3.00/mo. | Pass Plus, $2.99/month |
| 家族 | Families, $4.00/mo. | Pass Family, $4.99/month |
| チーム | Teams, $4.25/mo. | Pass Essentials, contact sales |
| 仕事 | Business, $7.00/mo. · Business MAX, $9.00/mo. | Pass Professional, contact sales |
ラストパス: Premium sits a cent above Pass Plus, but the ladder above it is far deeper. Business MAX at $9.00/mo. buys reporting no Proton tier matches. For teams, that ladder is the whole argument.
プロトンパス： The free tier costs nothing and caps nothing, which is rare. Proton Unlimited at $9.99/month bundles Proton Mail, Proton Drive, and Proton VPN for secure communication in one bill. Per seat, though, its premium plans run above NordPass and ビットワーデン.
さまざまなシナリオ
| もしあなたが…を必要とするなら… | 選ぶ | なぜ |

| Code you can inspect | プロトンパス | Open source and Cure53 audited |
| One vault for six people | ラストパス | Families at $4.00/mo. |

私たちのレビューで取り上げられなかったこと
This comparison focused on individuals, families, and small teams. We did not evaluate the Pass Essentials or Pass Professional business tiers, and we did not stress-test either vault past a few hundred entries. Our notes reflect the August 2026 builds. If you run 100 seats or need SCIM provisioning, your priorities will differ from what we covered here.

🏆 WINNER: LASTPASS
LastPass takes the overall spot on its 3.8 rating, though it wins only 3 of 8 categories.
最適な用途: families sharing one vault, 中小企業 managing staff logins, and anyone who needs emergency access.
That scorecard deserves an honest note. LastPass carries the higher rating and the deeper plan ladder, but Proton Pass wins more individual categories.
If you manage other people, LastPass is the practical pick. Provisioning, revocation, and password sharing across a team are things Proton has not matched yet.
If you are protecting one person’s accounts, the answer flips. Proton Pass is free, open source, and has never lost customer data.
Either choice beats reusing the same password everywhere. Pick one this week and start moving entries across.
