Why Use a Password Manager?

Modern life demands unique, strong passwords for every service. Remembering dozens—or hundreds—of random strings is impossible for most people. A password manager solves this by securely storing passwords and automatically filling them in when needed.

}

Initial Setup

  1. Create a master password that is long, unique, and memorable.
  2. Enable two‑factor authentication (2FA) for your vault.
  3. Sync across devices by signing into your account.

Adding and Organizing Passwords

Most managers allow you to create entries with custom fields, tags, and folders.

// Sample entry JSON export
{
  "title": "GitHub",
  "username": "jane.doe",
  "password": "zY5#l9VxR2p8!Q4w",
  "url": "https://github.com/login",
  "notes": "Personal account for open‑source projects.",
  "tags": ["development", "code"]
}

Security Best Practices

Troubleshooting Common Issues

Can't sync across devices?

Make sure you are logged in with the same account on all devices and that your internet connection is stable.

Forgot master password?

Most managers cannot recover lost master passwords. If you have a password hint or recovery key, use that. Otherwise, you may need to reset the vault, which will erase all stored data.
