AutoFill

AutoFill puts a username and a password into a login form. It never fills when a page loads. You always start it: a click, a key or a pick from a list. This page tells you how AutoFill works on each platform. The setup steps are on the page of each app.

All platforms share these rules:

Lasbolt fills only logins whose web address matches the page. It checks the address in the local agent, not in the page.
A secret value is not sent to the page until you pick the login.
An item can ask for your approval for each use. Then Lasbolt waits until you approve in the web app. See AI agents.
End-to-end (E2E) items fill only when the client is unlocked. On iOS, E2E items do not fill yet.

One extension code base serves Chrome and Firefox. Safari uses the same code inside the macOS app.

The extension talks to the local agent (lasbolt agent) through a native messaging host. You must have the lasbolt CLI installed and logged in. Run lasbolt integrate chrome --extension-id <ID> or lasbolt integrate firefox once to write the host manifest.
Start a fill in one of three ways: click the Lasbolt button in the toolbar and pick a login, press the shortcut (Ctrl+Shift+L, on macOS Command+Shift+L), or click the small icon in a login field.
The popup also searches your vault, copies a username or a password, and shows a one-time code. A copied password leaves the clipboard after 30 seconds, where the browser allows it.
A form in an iframe fills only if the frame has the same origin as the page.
The extension does not save new logins yet.

There is no extension in the Chrome Web Store or the Firefox add-ons site yet. You load a build from the source code. See Browser extensions.

The macOS app contains the Safari extension and runs the agent for you.

Turn on the Lasbolt extension in Safari. The app shows the steps in its Settings.
Fill works as in the browser extension: toolbar button, shortcut or field icon.
The app can copy a field of an item. It asks for your approval first when the item needs it.
The system AutoFill list of macOS and passkeys are not available. They need the paid Apple Developer Program.

See macOS app.

The iOS app has an AutoFill credential provider. Safari and apps show Lasbolt logins above the keyboard and in the password list.

Turn Lasbolt on in Settings > General > AutoFill & Passwords. The app shows the number of logins that are ready.
The extension reads a read-only copy of your logins that the app writes. It asks for your master password (or Face ID, when you turned it on) before it fills.
It fills passwords only. One-time codes and passkeys are not available. E2E items and items that ask for approval do not appear.
The credential provider needs a build with the paid Apple Developer Program. A free developer account cannot install it.

See iOS app.

The Android app is an Autofill service. Chrome and Firefox on Android fill through it. There is no browser extension on Android.

Turn Lasbolt on as the autofill service in the Android settings. The app has a button for this.
In Chrome, also turn on Settings > Autofill services > Autofill using another service. Firefox needs no extra setting.
When a login form gets focus, Lasbolt shows the matching logins. A locked agent shows one entry, Unlock Lasbolt.
Lasbolt fills only in Chrome and Firefox builds that it knows by their signing certificate. Other browsers get no fill.
It also fills one-time codes and cards, offers a strong password on sign-up forms, and saves a new login after you submit a form. You can turn Lasbolt off for one site.

See Android app.
