Login to Extension

Consumer customers can login to the Keeper browser extension with the Keeper email address and Master Password. If you are part of an Enterprise rollout, you may be directed to login with your Enterprise SSO Login credentials.

On the Chrome browser, the extension will automatically login when you login to the Web Vault. Other web browsers may require you to login separately to the Vault and Browser Extension.

For customers who login with SSO, you can type in the Enterprise Domain supplied by your Keeper Administrator.

Searching the Vault

You can search for any website login or other information stored in your Keeper vault from the KeeperFill extension. The search feature is case insensitive and will match any record within your vault.

Autofill Passwords

Clicking the Keeper lock allows you to quickly fill and login to the site. You can fill login and password by clicking on fill button or click on Show More to fill individual fields.

Filling Custom Fields

To have Keeper automatically fill custom fields into login forms, simply create a custom field in your record, in the web vault with the name of the form field (e.g. "Account Number"). If the name matches the field on the screen near the form field, Keeper will fill it for you.

Filling Custom Fields
Mapping Custom Fields to Form Fields

To make sure KeeperFill is able to locate the record in your vault to fill, be sure to set the Website Address in your record to the same domain as the website (e.g. amazon.com). To match multiple domains, simply create additional Website Address custom fields in your record.

Payment Cards & Identity

KeeperFill can also fill payment cards and identity information that are stored in your Vault. Payment cards are only available for filling on websites which you currently have a Keeper record in your vault.

Firefox and U2F Security Keys

While FIDO U2F support was added with the release of Firefox Quantum, the feature is turned off by default. In order to enable U2F support in Firefox Quantum, follow the steps below:

  1. Type "about:config" (without quotes) into the Firefox address bar and press Enter.

  2. Search for u2f.

  3. Double-click on security.webauth.u2f to enable U2F

Supported Keys

It’s important to understand that every FIDO U2F implementation can vary from the official specifications. Some sites supporting FIDO U2F have made accommodations for the incompleteness of Firefox’s implementation, but some have not. In other situations, some services may not work with Firefox Quantum because of a service-specific implementation.
