Browser Extension Version 17.8.0
In Preview
Overview
Currently in preview.
Keeper Browser Extension version 17.8.0 includes several security and usability improvements including an option to disable your browser's built-in password manager to prevent conflicts, anti-phishing protection that warns you before pasting passwords on unrecognized sites, support for adding custom fields to store sensitive information and a quick-copy option for easily sharing a record's UID.
New Features
Option to Disable Your Browser's Password Manager
Upon logging into the KeeperFill Browser Extension for the first time (or on a fresh install) you will be prompted to choose Keeper as your default password manager and import any passwords you have saved in your browser.
This eliminates potential conflicts between your browser's built-in password manager (including Google Chrome, Microsoft Edge, Opera, Brave and Firefox) and Keeper, ensuring you receive the best possible autofill experience without the hassle of manual configuration.
For step-by-step instructions, visit our end-user guide here (link pending).
These set up steps are optional but highly recommended. Click "Skip For Now" at the bottom of the extension window if you'd like to skip this process at any point during the set up wizard. You can also manage these features at any time from Keeper's Settings menu.
Following this update, an error message may appear in your browser window — if it does, just click "Turn on" or "Accept permissions" (depending on the browser) to allow Keeper to disable your browser's built-in password manager.
Verify Mode for Anti-Phishing Protection
Verify Mode helps protect you from accidentally entering your passwords on fake or malicious websites. When enabled, the extension monitors paste actions and warns you before your credentials are submitted to an unrecognized site.
How it works
When you paste a password into a login form, Keeper checks whether the site matches any of your vault records. If it doesn't, you'll see a real-time warning before anything is submitted, showing which site triggered the alert, with the option to proceed or cancel.
Protection levels
You can customize how aggressively the extension monitors your activity:
Medium: You'll only be warned if you copy a password from your vault and paste it into a different site than the one it's saved for.
High: You'll be warned any time you paste a password on a site that isn't saved in your vault at all, regardless of where the password came from.
Maximum: You'll always be asked to confirm before pasting a password, even on websites you've already saved and trust.
Choose a higher level of protection if you want more peace of mind, or a lower one if you prefer fewer interruptions during your normal browsing.
Added Support for Custom Fields
You can now add Custom Fields directly to your records from the browser extension — no need to switch to the web vault to make edits.
Click Add Custom Field within a record to create a Hidden Field for storing sensitive information such as security questions, PINs, or private notes alongside your login. This field type is masked by default to keep your data private.
Add as many custom fields as you'd like and simply reorder them with drag-and-drop. This functionality works the same across the Keeper web and mobile apps, so it should feel familiar.
Quick-Copy a Record UID
When viewing a saved record in the browser extension, click the info icon to reveal the record's unique Record ID (UID). From there, you can copy the UID or a shareable link by selecting the icons alongside it. Note that the link does not grant access to the record. The recipient must already have access rights for the link to work.
Passkey-Based Data Encryption Support
Keeper now supports an advanced passkey feature (WebAuthn PRF extension) that allows compatible websites to use your passkey for both authentication and data encryption. When a site supports this capability, Keeper handles it automatically on the backend with no extra steps required from you.
Important: If you attempt to delete a passkey that is being used for encryption by a website, Keeper will display a warning before you proceed. Deleting a passkey could prevent you from accessing your encrypted data on that site, so it's important to review this warning carefully before removing it.
Improvements
BE-6626: The Keeper browser extension now responds in real time to session management actions taken in the mobile app (lock, unlock, logout and remove). Any active extension sessions on other devices will update automatically.
BE-6910: Adding a passkey to a saved login record automatically upgrades it to the latest record format (v2→v3). Your existing credentials and notes are preserved throughout, and any errors are clearly surfaced. This works consistently across all supported browsers.
