KeePass is a free, open-source password manager. It stores all your passwords in one encrypted file (a “database”), so you only ever have to remember one password — the master password — instead of dozens.！

This guide explains, in simple terms, why you need a password manager, and how to actually use KeePass day-to-day.

A strong password is long, random, and not reused anywhere else. Real words, birthdays, and short passwords can be guessed or cracked quickly; long random strings of letters, numbers and symbols can't.

The problem: if you use the *same* strong password on every website and just one of those websites gets hacked, criminals now have the key to all your accounts. You should use a different, strong password for every single service you sign up for.

Nobody can remember 50+ random passwords. That's what a password manager is for.

A password manager is a program that:

• Generates strong, random passwords for you.
• Stores them all in one encrypted “vault”.
• Locks that vault with a single master password, which is the only one you need to remember.
• Fills in your saved passwords for you, so you never have to type or remember them yourself.

KeePass is one such tool. It's free, open source, and stores your passwords in a single file (a .kdbx database) that is encrypted with strong algorithms (AES-256, ChaCha20, Twofish). Because it's just one file, you can copy it to another computer, a USB stick, or a cloud drive like OneDrive or Google Drive.

1. Download and install KeePass (or use the portable version, which needs no installation — just unzip and run).
2. Click File → New… to create a new database.
3. Choose a strong master password. This is the single password you must remember from now on — make it long, e.g. a memorable sentence. If someone gets your database file and guesses this password, they get everything, so make it a good one.
4. Save the database file somewhere safe.

Right-click in the entry list and choose Add Entry…. For each entry you can fill in:

• Title – the name of the website or service.
• User name – your login name or email.
• Password – click the button next to the password field to generate a strong, random one automatically instead of typing your own.
• URL – the website address (clicking it later opens your browser).

Entries can be organized into groups (folders) on the left, e.g. “Email”, “Shopping”, “Work”. Use the search box to quickly find an entry again.

Don't forget to save the database (the disk icon) after making changes.

Once a password is stored, KeePass gives you a few ways to use it without ever having to read or type it yourself:

• Copy to clipboard. Double-click the user name or password cell in the entry list (or press Ctrl+B / Ctrl+C) to copy it. Paste it into the login form. KeePass automatically clears the clipboard again after a short time, for safety.
• Auto-Type. This is the most convenient method: KeePass can “type” your user name and password directly into the website's login form for you, as if you had typed it on the keyboard. Select the entry and use the global Auto-Type hotkey, or the Auto-Type command, and KeePass fills in the login boxes automatically.
• Drag & drop. You can drag a field straight from KeePass onto a target window.

KeePass has a plugin system: small add-ons, written by independent developers, that extend what KeePass can do. The core program stays simple, and you only add the extra features you personally need.

Plugins exist for almost everything, for example:

• Browser integration, so KeePass can auto-fill web forms directly.
• Automatic database backups.
• Two-factor / one-time-password (TOTP) generation.
• Importing passwords from other password managers or browsers.
• Syncing your database with cloud storage services.

Installing a plugin:

1. Download the plugin file (usually a .plgx or .dll file) from the KeePass Plugins page.
2. In KeePass, go to Tools → Plugins → Open Folder; this opens the “Plugins” folder.
3. Move the downloaded plugin file into that folder.
4. Restart KeePass — the plugin is now loaded and usually adds new menu items or options.

To remove a plugin, just delete its file from the Plugins folder and restart KeePass.

Plugins are written by different, independent authors, and the KeePass team can't check every single one for bugs. Only install plugins from sources you trust.

• Never reuse your master password anywhere else.
• Back up your database file regularly — if you lose it (and any key file, if you use one), your passwords are gone.
• Use the built-in password generator instead of inventing passwords yourself; it produces genuinely random, strong passwords.
