Autofill and saving logins
In the browser
When you focus a sign-in field, the extension offers matching logins. A login is offered only to the site it belongs to. Cards and identities have no site, so the same card can be used anywhere, but nothing is offered until you focus a field that asks for it, and no value leaves the background until you pick one item by hand.
The popup also has a Fill on this site action for the active tab.
When you sign in somewhere new, or change a password, the extension offers to save it.
On Android
Vaultiq is an Android autofill service for logins. Turn it on in system settings (see Install the Android app).
When a sign-in form appears, Android shows one suggestion, Fill with Vaultiq. Tapping it opens Vaultiq over the form. If the vault is locked you unlock it first (fingerprint or password). Then you see up to three matches, each with a Fill button, plus Search vault and Save new.
When you sign in to a new app or site, Android’s own “Save to Vaultiq?” prompt leads to a confirm sheet in Vaultiq.
Check who is asking
The sheet always shows who requested the fill. For a browser page it shows the verified website domain. For a native app it shows the app’s name and package, marked Not a verified website. A fake app can imitate a login screen, so read that line before you fill.
Limits
Identity and card autofill on Android is not built. Autofill never fills into Vaultiq’s own unlock fields.
