"KeePassHelper" provides a toolbar button that opens a floating panel at top center part of the currently selected page to display all the matching passwords based on the page URL. You can select an entry and paste either user-name or password to the currently selected input field. Also the extension can enter both user-name and password and press submit button all in once.


  1. What is "KeePassHelper" extension and how does it work?

    By default, the extension adds no element to your browser (instead of a toolbar button) nor performs any background credential checks hence it is ultra-lightweight. When a login is required, you can press the toolbar button (you can also assign a keyboard shortcut for this action) and check all credentials that are matched to the currently selected URL. Use arrow up and down keys to navigate through the credentials. Once a credential is selected, press Alt + U to insert username or press Alt + P to insert password or even press Alt + B to perform {USERNAME}{TAB}{PASSWORD} autotype rule.

    Note that username and password insertion only works when an input field is already selected before the panel gets opened.

  2. How can I use KeePassHelper extension on Windows OS

    For KeePassHelper extension to work you will need KeePass desktop application. You can get it from Also, you need to make sure KeePassHTTP plugin is installed in the KeePass application. This plugin is the communication bridge between your KeePassHelper extension and KeePass desktop application.

    To install KeePassHTTP plugin, drop KeePassHttp.plgx into the KeePass program file directory. To verify KeePassHttp has been installed correctly, go to Tools > Plugins and you should have KeePassHttp in there.

    Now open a web page which requires a password, then press the toolbar button. KeyPassHelper extension will send the request to KeePassHTTP plugin and this plugin opens a confirmation window. Click on the "allow" button for KeePass to store the communication token. That's it. You can now retrieve passwords from KeePass application directory.

    Note, KeePass application needs to be opened and database needs to be unlocked for KeePassHelper extension to be able to communicate with it.

  3. How can I use KeePassHelper extension on Mac OS?

    Install KeePassHelper extension on your browser. Install MacPass application on your Mac OS. Open a KeePass database using MacPass application. In the MacPass preferences, go to the plugins tab and make sure MacPassHTTP is enabled. Now open a webpage that requires login credentials in your browser. Focus the username field and then click on the toolbar icon of KeePassHelper extension. A notification box is opened in the MacPass window once asking for your consent whether this new token is permitted or not. Click on the allow button. That's it! Your KeePassHelper extension is now connected to MacPass and you can now get credentials on any page by opening the panel (popup).

    Note, MacPass application needs to be opened and database needs to be unlocked for KeePassHelper extension to be able to communicate with it.

  4. How can I define a keyboard shortcut for opening the command panel?

    Open chrome://extensions/ in a browser tab. At the bottom of the page, click on the "Keyboard shortcuts" link. Find "Find matched passwords and display them" and assign a keyboard shortcut for it. Alt + Shift + P combination is recommended.

    If keyboard shortcut is set you can perform a login as follows:

    • Alt + Shift + P to open the panel
    • Up and down key to find the credential
    • Alt + U to insert username at the currently selected element
    • Alt + P to insert password at the currently selected element
    • Alt + B to insert username at the currently selected element, then switch to the password field and insert password there and press the submit button; equals to {USERNAME}{TAB}{PASSWORD}{ENTER}
    • Alt + Shift + B to insert username at the currently selected element, then switch to the password field and insert password there (no submission); equals to {USERNAME}{TAB}{PASSWORD}

  5. How can I connect this extension to the KeePass or MacPass application?

    Press the toolbar button. If the extension does not have a stored pairing "key", it will send a request to the KeePass or MacPass application. You will need to allow the database access and then the extension will be able to send requests.

  6. What's new in this version?

    Please check the Logs section.

  7. Can I re-register this extension to KeePass?

    Simply delete the extension from your browser once and re-install it again. The extension will request a new key from KeePass or MacPass application.

  8. How can I close the panel?

    Hit ESC key or press the "Close" button.

  9. Can I change the search query once the panel is opened?

    Yes, when the panel is opened, top level URL is used for finding matching credentials. You can change the text and press Enter key to perform a new lookup. Note that at this moment, the query needs to be a URL. Performing custom search is yet not possible through HTTP communication.

  10. Can I save a new credential in my KeePass application without opening the actual application?

    Yes!, as of version 0.2.3, you can right-click over the toolbar button and select "Save a new login form in KeePass". This will bring up a panel that allows you to save login form to KeePass application.

    Note that KeePassHelper will try to guess all the fields based on the data you have already entered in the page. So it is better to first fill the form once in your browser and then hit the context menu item

    Always make sure to double check password field before requesting the save. Also, note that KeePassHelper only sends form data to KeePass application. If you really want to write the changes to your database, you still need to press Ctrl+S on the actual application.

  11. When I am using KeePassHelper extension on, Yahoo asks for account verification. Why is this happening and what is the workaround?

    Some websites like Yahoo check to make sure form submission is done by users. Basically, when submission event is dispatched by a button, there is a flag that refers to whether this is a user-initiated event or not. There is a simple workaround for this. Just ask KeePassHelper to fill the username and password and not submitting the form, then press the "Enter" key for the actual form submission.

  12. How can I insert additional values via String Fields?

    As of version 0.3.1, it is possible to fill additional input fields within the login form using string field entries (on KeePass application select an item and then use the right-click "Edit Entry" option. Go to the "Advanced tab" and define as many string fields as you like). Make sure your KeePassHelper is configured to send these string fields along with the credentials.

    Note that in oppose to the chromeIPass extension, KeePassHelper extension matches "Key" value with either "ID" or "NAME" attribute of all the input fields within the form and if there is a match, the value of that string field is being inserted. For instance if there is a HTML input element <input id="loginId" type="text" value=""> then define a string field with "Key" equals to KPH: loginId.

  13. How can I generate one-time-passwords (OTPs) with KeePassHelper extension?

    To generate OTPs, save OTP’s secret in the following format as a string field:

    • Key: KPH: otp
    • Value: key=OTP_SECRET


    • Key: KPH: sotp
    • Value: key=SECURE_OTP_SECRET

    To generate a secure OTP secret string, use the encryption tool in the right-click menu over the toolbar button. This tool helps you to protect any string data using a passphrase.

    When the popup is open, if either KPH: otp or KPH: sotp keys is detected, you can use the OTP button to store one-time tokens to the clipboard. It is also possible to insert the time-based tokens while filling the login form. To do so, find the element id and create a new string field in the following format:

    • Key: KPH: element's id or name
    • Value: {{TOTP}}

    Note: if KPH: sotp is detected, you will get a prompt to enter the passphrase whenever an insert command is used.

    Note: it is highly recommended to use KPH: sotp to have an additional protection if your database got compromised.

    Editorial Review

    In today’s world, people have accounts on different sites and platforms. This makes it challenging to remember the username and password. Long gone are the days when you had the same password for every account. Now, you are required to have long and complex passwords because of security reasons. This makes it difficult to remember the passwords and usernames of all the accounts. On of the best solutions for this problem is the KeePassHelper Password Manager. It will enable you to search and add the passwords and usernames from the KeePass application without copying them. Read on to know how it works.

    The KeePassHelper Password Manager extension is not so easy and simple use. You will need at have the KeePass application least version 2.17 or the latest to run it. Additionally, you will need to install KeePassHTTP plug-in. First of all, you must install KeePass application or any other compatible applications and then install the KeePassHTTP plug-in. After that, you will have to log into the KeePass and ensure the KeePassHTTP plug-in is properly installed. You can do this by going to the Tools -> Plugins options. Once, you have verified, you can start using this extension. You will have to go to a page that contains a password. Then, you should to go KeePassHelper's popup window to see the list of credentials available. Click on the lock icon on the toolbar; a new window will appear in the middle of the screen. You can now retrieve passwords and usernames from the window without any trouble. Furthermore, when you click on the toolbar icon, a new window will pop up. It will show all the matching passwords and usernames related to it. Through this extension, you enter login or password in the selected box. You can even add both the username and password. To make it easy for users, you can use direction keys to move up and down the list of credentials. For inserting a username, you can use “Alt + U”; for a password, you can use “Alt + P”, by pressing “Alt + B” you can insert both. A wonderful thing about this extension is that you can use it on different browsers including Chrome, Firefox, and Opera. The only drawback of this extension is that it is complex to use. You will have to keep in mind that you should choose the login name or password input box before inserting it. If the box is not selected insertion will not take place. This extension enables you to change the URL and conduct a new search. Another excellent feature of this extension is that it is lightweight in resources. However, some users had a challenging time using this. For a user, the Password option didn’t work. While for another user, there was an error connecting to the KeePass HTTP. For being able to use this extension, you need to install the KeePass application. Without this application, there will be no communication between the add-on and application. For permitting the communication, you need to open KeePass app and the database should be unlocked. Hence, use this extension and make it easy to manage your passwords.
