Our writers also spent hands-on time inside each vault.
それらのメモは、以下の「チームが気づいたこと」のセクションに記載されています。
By the end you will know which one fits your setup.
1Passwordとは何ですか？
1Password is a password manager built by アジャイル Bits in Toronto, Canada, in 2006.
It stores logins, secure notes, and card details behind one master password.
Everything is protected with AES 256 bit encryption and a zero knowledge policy.
A 34-character Secret Key is generated at signup and stored on your device.
That key sits inside your Emergency Kit, so keep the PDF somewhere safe.
Here is a walkthrough of how the entire app looks in daily use.
🏆 Winner: 1Password
Watchtower flags weak and reused passwords before they cost you. Travel Mode hides vaults at the border. Try it free for 14 days.
1Passwordの料金
There is no free version here. Every plan is paid, and each one starts with a trial.
| プラン | 価格 | 最適な用途 |
|---|---|---|
| 個人 | 月額2.99ドル | Personal users on a yearly subscription |
| 家族 | 月額4.99ドル | Up to 5 family members plus guest accounts |
| チームスターターパック | 月額19.95ドル | Small teams of up to 10 people |
| 仕事 | 月額7.99ドル | Per user, for mid to large company resources |
価格は2026年7月に確定しました。
無料トライアル: Yes. A 14 day free trial covers all personal plans, so you can test the entire app first.
返金保証: 1Password handles refunds case by case through email support rather than a fixed window.
📌 注記： The Families plan allows up to 5 users and lets you add more people for a small extra cost. Enterprise pricing is custom.
⚠️ 警告： Those monthly figures assume annual billing. Paying month to month costs more, and there is no free account to fall back on.
Key Benefits of 1Password
Here is what makes 1Password worth the subscription:
- ものみの塔特集： It watches your vault for weak, reused, and compromised passwords. It also warns you about any known データ 違反。
- 旅行モード: Sensitive information can be hidden when you cross borders. Chosen vaults simply vanish from the device.
- Secret Key layer: Your master password alone is not enough to open the vault. The 34-character key must also be present.
- Multiple vaults: Work, home, and shared vaults stay separate. Vault organization keeps clutter down as your list grows.
- Secure sharing: You can share passwords through links that expire. That beats sending files or plain text over chat.
- Passkey support: 1Password works with the FIDO Alliance on passwordless login. Biometric logins unlock the app on mobile.
- プライバシーカード： Virtual cards mask your real debit details during online shopping.

This video walks through the vault, the apps, and the setup steps.
🥈 Runner Up: Bitwarden

📌 注記： Premium works out to $10 per year and Families to $40 per year. Business accounts run $4 per user monthly for Teams and $6 for Enterprise.

Bitwardenの主なメリット
Here is what pulls people toward Bitwarden:

- セルフホスティング： You can run the whole server on your own hardware. Almost no rival offers this ability.

- Wide platform reach: Desktop apps, mobile apps, a web vault, and browser extensions for all major web browsers.
- 緊急アクセス: Trusted contacts can reach your vault if something happens to you.
- 2026 upgrades: A phishing blocker now stops fake login pages, and password coaching flags exposed credentials live.

機能比較
Both tools cover the basics well. The gaps show up in the details, so here are ten areas side by side.
| 特徴 | 1パスワード | ビットワーデン |
|---|---|---|
| 開始価格 | 月額2.99ドル | 0ドル（無料） |
| 無料プラン | ❌ | ✅ |
| 無制限のデバイス | ✅ | ✅ |
| Open Source Code | ❌ | ✅ |

| オペレーティングシステム | Windows macOS Linux アンドロイド iOS | Windows macOS Linux Android iOS |
| 最適な用途 | Families and business accounts | Budget and open source fans |
1. Password Management and Vault Setup
1パスワード: Setup starts with your master password and the Secret Key. You can then build multiple vaults for work, home, and shared logins. Everything from a Netflix login to a passport scan lives in one place.
ビットワーデン: The vault is flatter, using folders and collections instead of separate vaults. Its data importer pulls in a CSV file from another password manager or your browser in a few clicks.
2. Password Generator and Strong Passwords
1パスワード: パスワード ジェネレータ builds secure passwords and unique passwords as you sign up for new sites. Length and character rules are adjustable, and the result is saved without extra steps.
ビットワーデン: Its generator makes long, distinct strong passwords for every site, including passphrases. The free plan includes it, which is rare among free versions.
3. Username Generator and Email Aliases
1パスワード: A username generator creates masked email addresses for signups. That keeps personally identifiable information out of marketing lists during online shopping.
ビットワーデン: Custom domains let you tell the vault which sites share a login. Usernames and aliases can be generated through connected forwarding services.
4. Command Line and Developer Access
1パスワード: A command line tool pulls secrets into scripts and secure applications. Developers can keep API keys out of source code and log files.
ビットワーデン: Bitwarden also ships a CLI, and its open source licence means you can 監査 exactly what it does. Self-hosting on your own server appeals to the same crowd.
5. Watchtower and Password Health Reports
1パスワード: Watchtower scores every entry and surfaces weak passwords, reused passwords, and compromised passwords. It also warns you when a site suffers a data breach.
ビットワーデン: Vault health reports cover the same ground on paid plans. In 2026 the tool added live password coaching and a phishing blocker for safer security online.
⚠️ 警告： Bitwarden keeps its reports behind the premium version. Watchtower is included with every 1Password subscription.
6. 安全なパスワード共有
1パスワード: You can share passwords through links that expire on a schedule. Shared vaults and guest accounts let family members reach only what they need.
ビットワーデン: Sharing runs through Organizations, which hold collections that a group can open. Bitwarden Send handles one-off text and files with end-to-end encryption.
7. Business Accounts and Company Resources
1パスワード: The business plan adds admin controls, reporting, and policy rules over company resources. A Teams Starter Pack covers up to 10 people at a flat rate.
ビットワーデン: Teams and Enterprise plans undercut most rivals per seat. Admins can enforce policies, and self-hosting keeps data inside your own network.
8. Credentials Management and Account Recovery
1パスワード: Account recovery leans on the Emergency Kit and, for families, a trusted organiser. Lose both the key and the master password and nobody can help, since only you hold them.
ビットワーデン: You can export the vault to a file at any time, which makes migration painless. Emergency access hands a trusted contact a way in after a waiting period.
9. Apps, Browser Extensions and Access Management
1パスワード: The desktop app, mobile apps, and browser extensions stay in sync across multiple devices. Extended access management lets admins manage access to secure applications from one console. Biometric logins unlock the desktop version in a second.
ビットワーデン: Desktop apps, mobile apps, a web vault, and a browser extension cover all major web browsers. Biometric authentication works too, though credentials are automatically filled with one more click than rivals need. It is available in over 60 languages.
10. 価格設定とコスト
Here are the paid plans lined up next to each other.
| プラン | 1パスワード | ビットワーデン |
|---|---|---|
| 無料 | ❌（14日間無料トライアルのみ） | 永久に0ドル |
| 個人的 | Individual: $2.99/month | Premium: $1/month |
| ファミリープラン | Families: $4.99/month | Families: $3.33/month |
| Small team | Teams Starter Pack: $19.95/month | Not listed in our data sheet |
| 仕事 | Business: $7.99/month | Not listed in our data sheet |
1パスワード: You pay more, and you get Watchtower, Travel Mode, and tighter vault controls in return. The family plan is the strongest value in the lineup at $4.99 for five people.
ビットワーデン: Nothing else in the password manager market gives this much away for free. Premium at $1 a month buys reports, file attachments, and a built-in authenticator.
さまざまなシナリオ
| 必要な場合は | 選ぶ | なぜ |
|---|---|---|
| Zero cost | ビットワーデン | Free plan has no device limit |
| 家族で共有 | 1パスワード | Five users plus guest accounts |
| Auditable code | ビットワーデン | Open source and self-hosted |

💰 あなたの予算
If the budget is zero, the decision is already made. A free account with Bitwarden beats paying $2.99 for features you may not use.
🔌お使いのデバイス
Both run on Windows, macOS, Linux, Android, and iOS with no hard device cap. Check that your browser is covered before you commit.
🔐 Your Login Habits
Both let you enable two factor authentication by scanning a QR code with Google Authenticator. A hardware security key or a mailed verification code works too, so you never have to manually enter a shared secret for security purposes.
🎓 あなたの経験レベル
Non-technical users tend to settle into 1Password faster. Bitwarden rewards people who enjoy tinkering with settings and servers.
🆓 無料トライアルとデモ
Load twenty real logins into each tool before you decide. The trial is the fastest way to see which one you will actually open.
🛟 サポートオプション
Neither offers phone support. 1Password answers by email, and Bitwarden leans on community forums plus a large help library.

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 personal users, families, and small teams. We did not test enterprise rollouts, directory sync, or self-hosted deployments at scale. Certain features on business accounts, including custom reporting, sit outside what we could check. Prices and plan names reflect July 2026 and may shift. If you manage fifty or more seats, your priorities will differ from ours.

🏆 WINNER: 1PASSWORD
1Password wins 4 out of 6 categories.
最適な用途: families, frequent travellers, 中小企業 アカウント
These two sit at opposite ends of the same idea. 1Password sells a finished product with extras nobody else bundles. Bitwarden sells trust through open code and gives the basics away.
Bitwarden is the better pick if you want a free version that never nags you. It is also the favorite password manager of people who want to read the code themselves.
For most users, though, 1Password is the best password manager of the two. You get Watchtower, Travel Mode, and a family plan that covers everyone for $4.99.
