このガイドを信頼する理由
I moved my own logins into Keeper eight months ago and have tested every feature here on Windows, macOS, Linux and アンドロイド. Nothing below is copied from a marketing page.

Keeper is one of the most heavily certified パスワードマネージャー options available today.
Most people only ever use the autofill and stop there.
This guide shows you how to use Keeper Security properly, feature by feature.
Step by step, with screenshots and real tips.
Keeperセキュリティチュートリアル
This How to Use Keeper Security tutorial walks you through the Keeper password manager from first login to admin-level controls.

キーパーセキュリティ
Store every password, passkey and document in one encrypted vault. Keeper is a zero-knowledge platform, so your data is encrypted on your own device and never readable on Keeper servers. Personal plans start at $1.79 a month with a 30-day free trial.
Keeper Securityを使い始める
Before any feature makes sense, finish this one-time setup.
約3分かかります。
Here is what my own vault looked like after the first week:

それでは、各ステップを順を追って見ていきましょう。
ステップ1:キーパーアカウントを作成する
Go to the Keeper Security website and click Start Free Trial.
Enter your email address, then create your master password.
This one password unlocks your entire vault, so make it at least 16 characters with mixed case, numbers and symbols.
✓ チェックポイント: A confirmation email lands in your 受信トレイ within a minute.
ステップ2:アプリとブラウザ拡張機能をインストールする
Keeper runs as a web vault, a desktop app, a mobile app and a browser extension.
Install the desktop app plus the KeeperFill browser extension, since autofill only works with the extension in place.
Here’s what the setup gives you:

✓ チェックポイント: The Keeper icon appears in your browser toolbar and unlocks with your master password.
Step 3: Turn On MFA and Biometrics
You will be prompted to enable Multi-Factor Authentication during onboarding. Accept it.
Keeper supports FIDO2 WebAuthn hardware tokens, Google Authenticator, Microsoft Authenticator and SMS codes.
MFA is the single biggest step in protecting your Keeper account.
Then switch on biometrics for fast access on your phone, and save your 24-word recovery phrase somewhere offline.
✅ 完了: Your Keeper account is live and every feature below is now available.
Keeper Securityの強力なアドオンの使い方
強力なアドオン lets you bolt extra protection onto your plan without moving to another password manager.
以下に、その使用方法をステップごとに説明します。
Step 1: Open the Add-ons Page
Log in to the web vault and click your name in the top right corner.
Choose Account, then Add-Ons.
Step 2: Enable BreachWatch
Tick the box next to BreachWatch and confirm the purchase.
Keeper scans your saved login credentials against known breach data.
これがその様子です。

✓ チェックポイント: A coloured health score appears next to every record in your vault.
Step 3: Review the First Scan
Open BreachWatch from the left menu and work through anything marked high risk.
Change each weak or reused password before you close the report.
✅ 結果: BreachWatch now sends you a notification whenever a saved password shows up in a new breach.
💡 プロのヒント: Run the first scan late in the day. The initial pass flags a lot.
Keeper Securityリモートアクセスソリューションの使い方
Remote Access Solution lets you open RDP, SSH, VNC and database sessions straight from a browser tab.
以下に、その使用方法をステップごとに説明します。
Step 1: Add a Connection
Open Keeper Connection Manager and click New Connection.
Pick the protocol you need, such as SSH for a Linux server.
Step 2: Attach Credentials
Link the connection to an existing vault record instead of typing a password.
Keeper injects the credentials at launch, so the user never sees them.
これがその様子です。

✓ チェックポイント: The remote desktop or terminal loads inside the browser with no client install.
Step 3: Launch and Record
Click the connection name to start the session in your browser.
Turn on session recording if your organization needs an audit trail.
✅ 結果: Your team can reach production machines without ever holding the actual passwords.
💡 プロのヒント: Name connections after the machine role, not the hostname. Hostnames change; roles rarely do.
Keeper Securityのリモートブラウザ分離機能の使い方
リモートブラウザの分離 lets you keep malicious pages away from the machine sitting on your desk.
以下に、その使用方法をステップごとに説明します。
Step 1: Create an Isolated Session
In Connection Manager, add a connection and choose Remote Browser Isolation.
Paste the target URL into the address field.
Step 2: Set Session Rules
Decide whether to accept clipboard copying, file downloads and printing.
Most admins switch downloads off for anything outside the company.
これがその様子です。

✓ チェックポイント: The site loads in a streamed window with a session banner across the top.
ステップ3:閲覧を開始する
Click Connect and the page renders on Keeper’s servers, not yours.
Close the tab and the whole session is wiped.
✅ 結果: Suspicious links now open somewhere disposable instead of on your laptop.
💡 プロのヒント: Use isolation for vendor portals that demand old browser plugins. You get access without weakening your own browser.
Keeper Securityの安全なファイルストレージの使い方
安全なファイルストレージ lets you keep sensitive documents somewhere safer than a shared drive.
以下に、その使用方法をステップごとに説明します。
Step 1: Open or Create a Record
Pick an existing record, or create a new one using a purpose-built record type.
Record types keep the right fields together, for example a bank account.
Step 2: Add Attachments
Select Add Attachments inside the record and choose your file.
The file is encrypted on your device before it ever leaves it.
これがその様子です。

✓ チェックポイント: A paperclip icon appears on the record and the file opens from any device.
Step 3: Share It Safely
Use One-Time Share to send a document with a link that expires.
You can delete the share at any point without deleting the record.
✅ 結果: Your documents now sit behind the same zero-knowledge encryption as your login details.
💡 プロのヒント: Store scanned ID documents as attachments, not notes. Attachments never appear in search previews.
Keeper Securityゼロトラストサイバーセキュリティの使い方
ゼロトラストサイバーセキュリティ lets you stop treating the office network as automatically trustworthy.
以下に、その使用方法をステップごとに説明します。
Step 1: Turn On Enforcement Policies
Open the Admin Console and choose Roles, then Enforcement Policies.
Set minimum master password length and require multi-factor authentication.
Step 2: Restrict Devices
Approve デバイス individually so a stolen laptop cannot log in silently.
Configure inactivity logout so idle sessions close on their own.
✓ チェックポイント: New device logins now sit in a pending queue until an admin approves them.
Step 3: Watch the Audit Log
Open Advanced 報告 and track logins, shares and failed attempts.
Send alerts to your security channel so nothing waits for a weekly review.
✅ 結果: Access is granted per person and per device, which is what zero trust actually means.
💡 プロのヒント: Start enforcement with one pilot role. A full rollout buries your help desk in reset requests.
How to Use Keeper Security Password Manager
パスワード管理 lets you replace the reused passwords you have been carrying around for years.
以下に、その使用方法をステップごとに説明します。
ステップ1:既存のパスワードをインポートする
Choose Import in the web vault and pick Chrome, Firefox or a CSV file.
Then delete the saved copies in your browser and switch its password manager off.
Step 2: Generate Strong Replacements
Open Keeper’s password ジェネレータ when a site asks you to create a login.
Set the length to at least twenty characters and let Keeper save the record.
これがその様子です。

✓ チェックポイント: Your audit score climbs as each reused password is swapped out.
Step 3: Run a Security Audit
Open Security Audit to see which passwords are weak, old or reused.
Work down the list and replace the red entries first.
✅ 結果: Every account now has a unique password that you never have to remember.
💡 プロのヒント: Change your ten most valuable logins first: email, banking, and anything holding payment information. Everything else can wait a week.
How to Use Keeper Security Privileged Access Manager
特権アクセス管理 lets you keep the keys to your infrastructure out of spreadsheets and chat threads.
以下に、その使用方法をステップごとに説明します。
Step 1: Build a Shared Folder
Create a shared folder for each system, such as production databases.
Move the admin records into it and remove the personal copies.
Step 2: Assign Rights by Role
Give each team view-only or edit rights instead of full ownership.
View-only users can autofill a password without ever seeing the characters.
これがその様子です。

✓ チェックポイント: The shared folder lists every member and the exact rights they hold.
Step 3: Rotate on a Schedule
Turn on password rotation for service accounts you cannot manually track.
Keeper updates the record and the target system in the same process.
✅ 結果: Admin credentials are now managed centrally, so an offboarding takes one click.
💡 プロのヒント: Audit shared folder membership every quarter. Access tends to accumulate quietly as people move between teams.
How to Use Keeper Security for MSPs
MSP lets you keep client data separated while still managing it from one console.
以下に、その使用方法をステップごとに説明します。
Step 1: Open the MSP Console
Log in to Keeper MSP and add each client as its own managed company.
Every client gets an isolated tenant with its own encryption keys.
Step 2: Allocate Licences
Assign licences from your pool and change the count as clients grow.
Billing follows the licences you actually have in use.
これがその様子です。

✓ チェックポイント: Each managed company appears in the console with its own licence count.
Step 3: Delegate Admin Access
Add a technician to a client tenant with a scoped admin role.
Remove that access the moment the contract ends.
✅ 結果: You can support dozens of clients without mixing a single record between them.
💡 プロのヒント: Book the MSP demo before you purchase. Licence pooling is easier to see live than in the docs.
Keeper Securityのプロ向けヒントとショートカット
After eight months of daily use, these are the habits that saved me the most time.
キーボードショートカット
| アクション | ショートカット |
|---|---|
| Open the KeeperFill menu | Ctrl + Shift + K |
| Fill the matching login | Ctrl + Shift + L |
| Create a new password | Ctrl + Shift + G |
| Lock the vault 即座に | Ctrl + Shift + X |
You can change any of these in the extension settings, and Keeper’s own tutorials cover the rest.
ほとんどの人が見逃す隠れた機能
- 1回限りの株式: Send a password to someone with no Keeper account. The link expires on a timer you set.
- 緊急アクセス: Designate up to five trusted contacts who can reach your vault after a waiting period.
- オフラインモード: Keeper keeps a local encrypted copy, so your vault still opens on a device you have logged into before.
- Quiet discounts: Students get 50% off and military, first responders, nurses and doctors get 30% off.
キーパーのセキュリティに関するよくある間違いを避ける
Mistake #1: Leaving passwords in your browser
❌ 間違い: Importing into Keeper and letting Chrome keep its own saved copies.
✅ 右: Delete the browser copies and switch its password manager off. Two managers fighting over one form is the most common autofill problem people report.
Mistake #2: Treating the master password like any other password
❌ 間違い: Reusing an old password, or storing the master password inside the vault it unlocks.
✅ 右: Use a long passphrase you can recall without help, and keep the 24-word recovery phrase on paper. Keeper cannot reset it for you.
Mistake #3: Skipping the security audit
❌ 間違い: Importing 300 logins and never looking at them again.
✅ 右: Run Security Audit monthly. That practice is what turns a password manager into a real security upgrade.
Keeperセキュリティのトラブルシューティング
Problem: Autofill does nothing on a login page
原因: The site uses a non-standard form, or the extension is locked.
修理: Click the Keeper icon, unlock it, then use Add to Existing Record so KeeperFill learns that page.
Problem: Your vault will not sync between devices
原因: The app is holding an offline copy from a previous session.
修理: Log out fully, log back in with an internet connection, and pull down to refresh on mobile.
Problem: You are locked out after losing your MFA device
原因: Keeper cannot see your encryption keys, so support cannot bypass MFA for you.
修理: Use a backup code or a second registered token. If both are gone, your recovery phrase is the only route back.
📌 注記: If none of these fix your issue, contact Keeper Security support directly.
Keeper Securityとは何ですか?
キーパーセキュリティ is a password manager and security platform that stores your credentials, files and payment information in one encrypted vault.
Think of it like a bank vault where you hold the only key and the bank cannot open the door.
Many password managers stop at storing logins. Keeper keeps going into file storage, dark web monitoring and admin controls.
こちらの簡単な概要をご覧ください。
These are the core features you get:
- 強力なアドオン: Extend your Keeper vault with BreachWatch dark web monitoring and extra secure file storage.
- リモートアクセスソリューション: Reach internal machines through Keeper Connection Manager without a VPN client.
- リモートブラウザの分離: Open risky web apps inside a sandboxed browser that never touches your device.
- 安全なファイルストレージ: Store passports, contracts and payment information in the same encrypted vault as your passwords.
- ゼロトラスト・サイバーセキュリティ: Verify every user and device before granting access to company data.
- パスワード管理: Generate, autofill and audit every password you own from one place.
- 特権アクセス管理: Control admin credentials, service accounts and secrets across your 仕事.
- MSPs: Run separate, isolated vaults for every client you manage.
Keeper is a zero-knowledge platform. Your data is encrypted and decrypted locally on your device using AES 256-bit encryption at the record level. Keeper Security employees have no ability to decrypt customer data because you hold the keys.
That is also why Keeper has never had vault contents exposed. In the event the servers were hacked, the stored data would stay unreadable.
It is SOC 2 certified, ISO 27001, 27017 and 27018 certified, FedRAMP Authorized and StateRAMP authorized.
