KeePass Password Safe is a free and open-source password manager primarily for Windows. It officially supports macOS and Linux operating systems through the use of Mono. Additionally, there are several unofficial ports for Windows Phone, Android, iOS, and BlackBerry devices. KeePass stores usernames, passwords, and other fields, including free-form notes and file attachments, in an encrypted file. This file can be protected by a master password, key file, and/or the current Windows account details. By default, the KeePass database is stored on a local file system (as opposed to cloud storage).
KeePass supports a number of plugins. It has a password generator and synchronization function, supports two-factor authentication, and has a Secure Desktop mode. It can use a two-channel auto-type obfuscation feature to offer additional protection against keyloggers. KeePass can import from over 30 other most commonly used password managers.
A 2017 Consumer Reports article described KeePass as one of the four most widely used password managers (alongside 1Password, Dashlane and LastPass), being "popular among tech enthusiasts" and offering the same level of security as non-free competitors but being more difficult to install.

Overview
Password management
Passwords stored by this application can be further divided into manageable groups. Each group can have an identifying icon. Groups can be further divided into subgroups in a tree-like organization.
Further, KeePass tracks the creation time, modification time, last access time, and expiration time of each password stored. Files can be attached and stored with a password record, or text notes can be entered with the password details. Each password record can also have an associated icon.
Import and export
The password list is saved by default as a .kdbx file, however it can be exported to various formats like TXT, HTML, XML and CSV. The XML output can be used in other applications and re-imported into KeePass using a plugin. The CSV output is compatible with many other password safes like the commercial closed-source Password Keeper and the closed-source Password Agent. Also, the CSVs can be imported by spreadsheet applications like Microsoft Excel or OpenOffice/LibreOffice Calc. Exports from these programs can be imported to KeePass databases. KeePass can parse and import TXT outputs of CodeWalletPro, a commercial closed-source password safe. It can import TXT files created by Bruce Schneier's Password Safe v2. File format support can be expanded through the use of KeePass plugins.
Multi-user support
Keepass supports simultaneous access and simultaneous changes to a shared password file by multiple computers (often by using a shared network drive), however there is no provisioning of access per-group or per-entry. As of May 2014, there are no plugins available to add provisioned multi-user support, but there exists a proprietary password server (Pleasant Password Server) that is compatible with the KeePass client and includes provisioning.
Auto-type, global auto-type hot keys, and drag and drop
KeePass can minimize itself and type the information of the currently selected entry into dialogs, webforms, etc. KeePass has a global auto-type hot key. When KeePass is running in the background (with opened database) and the user presses the hot key, it looks up the correct entry and executes its auto-type sequence. All fields, title, username, password, URL and notes can be drag and dropped into other windows.
Windows clipboard handling allows double-clicking on any field of the password list to copy its value to the Windows clipboard. KeePass can clear the clipboard automatically some time after the user has copied one of their passwords into it. KeePass features a protection against clipboard monitors (other applications won't get notifications that the clipboard content has been changed).
It did have a paste-once functionality: allow only one paste operation, after pasting, the clipboard is cleared automatically by KeePass, but this was removed in version 2.x due to incompatibility and insufficient effectiveness.
Browser support
The auto-type functionality works with all windows, and consequently with all browsers. The KeeForm extension allows users to open websites with Internet Explorer and Mozilla Firefox and fill in user details automatically. For Internet Explorer, there's also a browser integration toolbar available.
For Firefox there's another extension called KeeFox which connects to KeePass when a user needs to access a password from it.
Built-in password generator
KeePass features a built-in password generator that generates random passwords. Random seeding can be done through user input (mouse movement and random keyboard input).
Plugins
KeePass has a plugin architecture. There are various plugins available from the KeePass website (such as import/export from/to various other formats, database backup, integration and automation, etc.). Note that plugins may compromise the security of KeePass, because they are written by independent authors and have full access to the KeePass database.

Cryptography
Runtime security
According to the utility's author, KeePass was one of the first password management utilities to use security-enhanced password edit controls, in this case one called CSecureEditEx. The author makes several claims regarding the security of the control and its resistance to password revealing utilities; however, the author does not cite or make any references to any third-party testing of the control to corroborate the claims of its security.
Passwords are protected in memory while KeePass is running. On Windows Vista and later versions, passwords are encrypted in process memory using Windows Data Protection API, which allows storing the key for memory protection in a secure, non-swappable memory area. On previous Windows systems, KeePass falls back to using the ARC4 cipher with a temporary, random session key.
Offline security
Access to the database is restricted by a master password or a key file. Both methods may be combined to create a "composite master key". If both methods are used, then both must be present to access the password database. KeePass version 2.x introduces a third option--dependency upon the current Windows user. KeePass encrypts the database with the AES or Twofish symmetric ciphers. The kdbx database is encrypted with AES in CBC/PKCS7 mode without proper authentication, as there are only SHA2 hashes guarding the integrity of ciphertext, while these might catch a typical file corruption they will not prevent malicious tampering. AES is the default option, and Twofish is available in 1.x, but is not available in version 2.x. However, a separate plugin provides Twofish as an encryption algorithm. Beginning with version 2.35 ChaCha20 cipher is also available.
