⚡ 簡単な評価:
- 価格: Bitwarden runs Free: $0, Premium: $1, Families: $3.33. LastPass starts at Premium: $3.00/mo. and tops out at 仕事 MAX: $9.00/mo.
- 最適な用途: Bitwarden suits people who want open source code and a real free account. LastPass suits people who want dark web monitoring and emergency access built in.
- 主な違い： Bitwarden publishes its source code and funds third party security audits. LastPass keeps its code closed.
- 私たちのおすすめ： Bitwarden, rated 4.5 against 3.8, because the free plan covers unlimited passwords on unlimited devices.
ほとんどの人は パスワードマネージャー once and stay for years.
That makes the first choice worth a few minutes of thought.
LastPass has been a popular パスワードマネージャー since the browser toolbar era.
Bitwarden arrived later with open source code and a free version that never nags you.
Both work as a secure password manager, keeping login credentials behind one master password.
The gap shows up in price, transparency, and what the free plan actually gives you.
概要
This LastPass vs Bitwarden comparison covers pricing, security features, and everyday password management.
We also look at who each password manager fits best.

Pricing comes straight from each vendor’s published plans.
LastPassとは何ですか？
LastPass is a password manager that stores login credentials in a cloud vault.
You sign in to your LastPass account with one master password.
The LastPass vault then fills usernames and passwords for you.
The LastPass browser extension works in Chrome, Firefox, Edge, and Safari.
Older builds even supported Internet Explorer before Microsoft retired it.
Plans cover home users, LastPass Families, LastPass Teams, and LastPass Business.
Our full LastPass review goes deeper into the LastPass features listed below.
Here is a walkthrough of the vault and its main screens.
ラストパス
A familiar vault with dark web monitoring and emergency access. Best if you want those extras without adding a second app.
LastPassの料金
Here is what the paid plans cost.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| プレミアム | 月額3.00ドル | One person who wants every consumer feature |
| 家族 | 月額4.00ドル | Shared folders for a household |
| チーム | 月額4.25ドル | Small groups needing basic user management |

Pricing verified August 2026.
無料トライアル: Premium and Families offer a 30-day trial. No card is needed to start.
返金保証: Paid plans carry a 30-day refund window from purchase.
📌 注記： Premium adds 1GB of encrypted file storage, dark web monitoring, and emergency access. The Families plan repeats those perks across six vaults.
⚠️ Pricing conflict: 私たちの データ sheet lists LastPass paid tiers only. A LastPass free version still exists, but the free version limits users to one device type — computers or phones, not both. Treat the table above as the paid plan reference and check the vendor page before you buy.
Key Benefits of LastPass
Here is what LastPass does well:
- ダークウェブの監視： LastPass watches breach dumps for your email addresses. You get alerts when data breaches expose an account you saved.
- LastPass Security Dashboard: The security dashboard scores your stored passwords. It flags weak passwords and reused entries in one list.
- 緊急アクセス: A trusted contact can request your vault after a waiting period. Useful for spouses and executors.
- Passwordless login: The LastPass Authenticator app can unlock the vault without typing a complex master password every time.
- Encrypted file storage: Premium includes 1GB for scans of passports and 保険 papers alongside secure notes.
- Business controls: LastPass Business adds access management, user management, and directory sync for admins.

LastPass Pros & Cons
✅ メリット
- Dark web monitoring and password reminders come with Premium
- Emergency access hands your vault to a trusted person
- Passwordless login through the LastPass Authenticator
- Admin tools for LastPass Teams and LastPass Business
❌ デメリット
- The 2022 security incident copied backup vault data from LastPass servers
- Closed code means no outside reader can audit it
- Free users get one device type, so phones and laptops do not sync together
Bitwarden とは何ですか?
Bitwarden is an open source password manager for personal accounts and business accounts.
Anyone can read the code on GitHub and check what the app does.
The Bitwarden password manager encrypts your vault with AES 256 before it leaves your device.
That 256 bit key comes from your master password, so only you can decrypt it.
There are desktop apps for Windows, macOS, and Linux, plus mobile apps for iOS and アンドロイド.
A browser extension covers all major web browsers.
This walkthrough shows the vault, the apps, and the sync settings.
🏆 受賞者：Bitwarden
Open code, published security audits, and a free plan with unlimited passwords on unlimited devices.
Bitwardenの価格設定
Here is what Bitwarden offers on its consumer tiers.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 無料 | $0 | Unlimited passwords across unlimited devices |
| プレミアム | $1 | Vault health reports, file sharing, and a built-in authenticator |
| 家族 | $3.33 | Six accounts with a shared collection |
Pricing verified August 2026.
無料トライアル: The free account never expires. Paid plans add a short trial window.
返金保証: Bitwarden refunds paid plans within 30 days of purchase.
📌 注記： Premium features include emergency access, 1GB of encrypted file storage, and vault health reports. Business accounts sit on separate per-user pricing.
⚠️ 請求に関する注記： These prices are billed yearly, so the monthly figure only applies if you pay for twelve months up front. Check the plan page before you subscribe.
Bitwardenの主なメリット
Here is what pushes Bitwarden ahead for most users:
- Open source and audited: Third party security firms run yearly security audits and publish the reports. Few other password managers do both.
- A free plan worth using: The free version syncs unlimited passwords across unlimited devices, which most free versions do not allow.
- Zero knowledge design: Encryption happens on your device. The server stores encrypted data it cannot read.
- Bitwarden 送信: Share a file or a 文章 note through an expiring link. Handy for sensitive information you do not want sitting in email.
- Two factor authentication choices: Free accounts support email and authenticator apps such as Google Authenticator. Premium adds YubiKey and Duo.
- セルフホスティング： You can run Bitwarden on your own server if you want the vault under your roof. The docs find instructions for Docker in a few clicks.

1. Password Vault and Storage
ラストパス: The vault holds all your passwords plus secure notes, cards, and addresses. Everything sits in folders you can rename. Password management here feels close to a filing cabinet with a search bar on top.
ビットワーデン: The secure vault uses items and collections instead of folders alone. Its importer reads files from most password managers, so moving stored passwords in takes minutes.
2. Free Version Limits
ラストパス: LastPass free gives unlimited password storage on one device type. Pick computers and your phone drops off. That single rule pushes most free users toward a paid tier.
ビットワーデン: The free account syncs unlimited passwords to a laptop, a tablet, and a phone at once. You lose vault reports and file sharing, not basic access.
💡 プロのヒント: If you only ever log in from one laptop, the free version gap will not affect you. Everyone else should count their devices first.
3. 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 sets length, digits, and symbols from the extension or the LastPass mobile app. It saves a new secure password to the entry as you create the account.
ビットワーデン: Password generation covers random strings and passphrases, and it keeps a history of what it made. Passphrases help when a site rejects symbols but you still want unique passwords.
4. Multifactor Authentication
ラストパス: Multi factor authentication runs through the LastPass Authenticator, hardware keys, or biometric authentication on a mobile device. Business MAX adds adaptive rules for staff logins.
ビットワーデン: Two factor authentication works on the free tier with any authenticator app. The premium version adds hardware keys, and the built-in code generator replaces a separate app.
5. Dark Web Monitoring and Reports
ラストパス: Dark web monitoring checks breach lists for your email and warns you when personally identifiable information leaks. The LastPass security dashboard turns that into one score.
ビットワーデン: Vault health reports list weak passwords, reused entries, and accounts caught in known data breaches. The reports live behind the premium plan.
6. Master Password and Passwordless Login
ラストパス: Passwordless login lets the authenticator app approve access instead of typing a complex master password. You still need that master password during recovery.
ビットワーデン: Login with device approves a new sign-in from a phone you already trust. Biometrics unlock the app after that first login on each device.
⚠️ 警告： Neither company can reset your master password for you. Lose it without a recovery method and the encrypted data stays locked forever.
7. 保存して自動入力
ラストパス: The LastPass extension offers to save a login the moment you submit a form. Autofill also handles multi-page sign-ins where the username and password sit on different screens.
ビットワーデン: Custom domains tell the browser extension that two addresses belong to the same company, which fixes most missed fills. Browser extensions on Chrome, Firefox, Safari, and Edge all behave the same way.
8. Password Sharing and Emergency Access
ラストパス: Password sharing runs through shared folders, and recipients can use an entry without seeing the characters. Emergency access hands the whole vault to a named contact after a delay you set.
ビットワーデン: Families and business accounts get shared collections, while Bitwarden Send moves a one-off secret to anyone with a link. Emergency access sits in the paid tiers.
9. Open Code and Data Portability
ラストパス: The code is closed, so outside researchers cannot inspect how encrypted passwords are handled. Export works, but it produces a plain file you must delete straight after import.
ビットワーデン: Export vault produces JSON or CSV, and an encrypted export option protects the file with a password. Because the client code is public, security researchers review it without asking permission.
10. 価格設定とコスト
Here are the paid plans side by side.
| ティア | ラストパス | ビットワーデン |
|---|---|---|
| 無料 | Not listed in paid plans | 無料：0ドル |
| 個人 | Premium: $3.00/mo. | Premium: $1 |
| 家族 | Families: $4.00/mo. | Families: $3.33 |
| Small team | Teams: $4.25/mo. | Separate business pricing |
| 会社 | Business: $7.00/mo. and Business MAX: $9.00/mo. | Separate business pricing |
ラストパス: You pay $3.00/mo. for the features that make the product interesting, including dark web monitoring and encrypted file storage. The jump to Business at $7.00/mo. buys access management rather than better password security.
ビットワーデン: Premium at $1 costs less than a coffee refill per year, and the free tier already covers the core job. Families at $3.33 undercuts the LastPass equivalent while adding six vaults.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| A free password manager | ビットワーデン | Free plan covers every device |
| Dark web alerts built in | ラストパス | Monitoring ships with Premium |
| Open code you can inspect | ビットワーデン | Public repository and audits |
| Emergency access for family | ラストパス | Included at $3.00/mo. |
| The lowest yearly bill | ビットワーデン | Premium: $1 against $3.00/mo. |
| Admin controls for staff | ラストパス | Business tiers add user management |
💰 あなたの予算
Bitwarden asks $1 for its premium features, while LastPass Premium sits at $3.00/mo. Over a household of six the Families gap widens further.
🔌お使いのデバイス
Count your phones and laptops before choosing a free tier. Only one of these two syncs a free vault to every device you own.
🔐 Your Trust Model
Some people want to read the code that guards their vault. Others are fine trusting a vendor’s word, which is how many password managers still operate.
🎓 あなたの経験レベル
Both apps guide a beginner through setup in under ten minutes. Self-hosting a server is the only step that needs real technical support.
🆓 無料トライアルとデモ
You can test LastPass Premium for 30 days without paying. Bitwarden lets you stay on the free account for as long as you like.
🛟 サポートオプション
Both run email support with a public help centre and community forum. Neither bundles a virtual private network, so budget for that separately if you want one.

私たちのレビューで取り上げられなかったこと
We looked at personal accounts and small teams. We did not test enterprise SSO, directory sync at scale, or bulk licensing. Our notes reflect the August 2026 builds, and both products change often. If you manage hundreds of staff, your priorities will differ from what we covered here.

🏆 優勝：ビットワーデン
Bitwarden wins 4 of 7 categories and scores 4.5 against 3.8.
最適な用途: budget-conscious users, people who want open code, households with mixed devices
The two products aim at different buyers. Bitwarden treats secure password management as a utility and charges accordingly. LastPass sells a bundle where monitoring and recovery tools ride along with the vault.
LastPass still earns a look if you want those extras without stitching apps together. Its dashboard makes good password hygiene easy to measure, and its admin console beats the Bitwarden equivalent for smaller offices.
Security breaches shape reputations, and the 2022 security incident remains the sticking point for many LastPass users. Bitwarden has not had a comparable event, and its public code lets outsiders check the claims. For most people that combination, plus the price, settles it.

よくある質問
LastPassとBitwarden、どちらが良いですか？
Bitwarden, for most people. It scores 4.5 to 3.8 here, costs less, and publishes its code. Choose the alternative if you want dark web alerts bundled in.
LastPassは今でも優れたパスワードマネージャーですか？
It still protects a vault with strong encryption and useful extras. The 2022 breach damaged trust, so weigh that against the features before you renew.
Bitwarden は本当に無料ですか?
Yes. The free tier costs $0 and stores unlimited passwords on unlimited devices. Paid plans add vault reports, file sharing, and emergency access.
なぜ人々はLastPassから離れていくのか？
Two reasons come up most: the 2022 incident that exposed backup vault copies, and the free tier limit of one device type. Cheaper rivals did the rest.

Premium is listed at $1 and Families at $3.33 on a monthly basis, billed annually. The free plan stays free with no time limit.
