Frequently Asked Questions
Which browsers are supported?
Chrome, Firefox, and Edge. All Chromium-based browsers (Brave, Arc, Opera) can install the Chrome extension.
Is Safari supported?
Not yet. Safari is on our roadmap. Use the Locke iOS app for password management on Apple devices.
Does it work offline?
Yes. The extension caches your vault locally (encrypted), so autofill works even when you're offline.
Can I disable it on certain sites?
Yes. Exclude sites from the extension popup. Business users can use Domain Ignore List in Locke Armory to disable it organization-wide on specified domains.
