KeePass is a highly secure and popular open-source password manager used to store and manage passwords, usernames, and other sensitive information in a secure manner. It was developed by Dominik Reichl and is available for various platforms, including Windows, macOS, Linux, and mobile devices.

One of KeePass's key features is its robust security. It employs strong encryption algorithms (e.g., AES, Twofish) to safeguard stored data, ensuring that only authorized users with the master password can access their passwords. The master password serves as the primary key to unlock the encrypted database.

KeePass provides a user-friendly interface, allowing users to organize their passwords in a structured manner using folders and categories. Additionally, it offers password generation tools, helping users create complex and unique passwords to enhance security.

The software enables users to quickly search for specific passwords and offers features like auto-type, which allows automatic filling of login forms for websites and applications. KeePass also supports plugins, extending its functionality and making it customizable to meet individual needs.

Moreover, KeePass emphasizes portability and accessibility by allowing users to store their encrypted password database on various storage mediums, such as local drives, USB drives, or cloud storage. This allows users to access their passwords from different devices while maintaining security and privacy.

Overall, KeePass is a reliable and secure password management solution that helps users keep their sensitive information organized and protected.

• Auto-Type Functionality: Automates entering usernames and passwords.
• Password Generator: Creates strong, random passwords.
• Organize Passwords: Categorize passwords into groups and subgroups.
• Search & Filter: Quickly find specific entries.
• Custom Fields: Add extra information to entries.
• Attachments: Securely attach files to password entries.
• Security Features: Offers additional security options.
• Cross-Platform: Accessible on various operating systems.
• Plugins & Extensions: Extend functionality with additional features.
• Import & Export: Import/export passwords easily.
• Database Synchronization: Sync the database across devices securely.

• The estimated password quality (in bits) is now displayed on the quality progress bar, and right of the quality progress bar the length of the password is displayed.
• Auto-Type: before sending a character using a key combination involving at least two modifiers, KeePass now first tests whether this key combination is a registered system-wide hot key, and, if so, tries to send the character as a Unicode packet instead.
• Auto-Type: added workaround for Cygwin's default Ctrl+Alt behavior (which differs from Windows' behavior).
• Auto-Type: added {APPACTIVATE ...} command.
• {HMACOTP} placeholder: added support for specifying the shared secret using the entry strings 'HmacOtp-Secret-Hex' (secret as hex string), 'HmacOtp-Secret-Base32' (secret as Base32 string) and 'HmacOtp-Secret-Base64' (secret as Base64 string).
• {T-CONV:...} placeholder: added 'Uri-Dec' type (for converting the string to its URI-unescaped representation).
• Added placeholders: {URL:USERINFO}, {URL:USERNAME} and {URL:PASSWORD}.
• Added placeholders: {BASE}, {BASE:RMVSCM}, {BASE:SCM}, {BASE:HOST}, {BASE:PORT}, {BASE:PATH}, {BASE:QUERY}, {BASE:USERINFO}, {BASE:USERNAME}, {BASE:PASSWORD} (within an URL override, each of these placeholders is replaced by the specified part of the string that is being overridden).
• Added {NEWPASSWORD:/Profile/} placeholder, which generates a new password for the current entry using the specified password generator profile.
• Pattern-based password generator: the '^' character now removes the next character from the current custom character set (for example, [a^y] contains all lower-case alphanumeric characters except 'y').
• Enhanced syntax highlighting in the sequence field of the 'Edit Auto-Type Item' dialog.
• Added option 'Do not ask whether to synchronize or overwrite; force synchronization'.
• Added synchronization support for the group behavior properties 'Auto-Type for entries in this group' and 'Searching entries in this group'.
• Root group properties are now synchronized based on the last modification time.
• While saving a database, a shutdown block reason is now specified.
• Added 'Move to Group' menu in the 'Selected Entries' popup of the main entry list context menu.
• Items of dynamic menus (tags, strings, attachments, password generator profiles, ...) now have auto-assigned accelerator keys.
• As alternative to Ctrl+F, pressing F3 in the main window now displays the 'Find' dialog.
• Added UIFlags bit for hiding password quality progress bars and information labels.
• Enhanced system font detection on Unix-like systems.
• When using 'xsel' for clipboard operations on Unix-like systems, text is now copied into both the primary selection and the clipboard.
• Added '--version' command line option (for Unix-like systems).
• Plugins can now subscribe to an IPC event that is raised when running KeePass with the '-e:' command line parameter.
• Added workaround for .NET AutoWordSelection bug.
• Added workaround for Mono bug 10163; saving files using WebDAV now also works under Mono 2.11 and higher.
• Added workaround for Mono image tabs bug.
• Added workaround for Mono NumericUpDown drawing bug.

• Merged the URL scheme overrides and the 'Override all URLs' option into a new dialog 'URL Overrides'.
• Improved autocompletion of IO connection parameters using the MRU list (now treating the user name as filter).
• Improved interaction of IO connection trigger parameters and the MRU list.
• The master key prompt dialog now validates key files only when clicking [OK], and invalid ones are not removed automatically from the list anymore.
• Improved support for managing columns leftover from uninstalled plugins in the 'Configure Columns' dialog.
• If the 'Unhide Passwords' policy is turned off, the passwords column in the auto-type entry selection dialog is now unavailable.
• The entry list in the main window is now updated immediately after performing auto-type or copying data to the clipboard.
• Various list view performance improvements.
• The 'Searching entries in this group' group behavior properties are now ignored during resolving field references.
• Improved behavior in case of syntax errors in placeholders with parameters.
• Two-channel auto-type obfuscation: improved realization of clipboard paste commands.
• General main window keyboard shortcuts now also work within the quick search box and the database tab bar.
• Pressing Ctrl+Shift+Tab in the main window now always selects the previous database tab (independent of which control has the focus).
• Changed shortcut keys for moving entries/groups on Unix-like systems, due to Mono's incorrect handling of Alt (preventing key events) and navigation keys (selection updated at the wrong time).
• Auto-Type: improved modifier key releasing on Unix-like systems.
• Various code optimizations.
• Minor other improvements.

• A key-up event to the groups tree in the main window without a corresponding key-down event does not change the entry list anymore.
