Edge inherited Chrome's extension ecosystem, which means any Chromium-based vault extension installs the same way and behaves identically. The main difference is where you find the extensions store and a couple of Edge-specific settings worth checking.
Edge's built-in saver is tied to your Microsoft account and syncs only across Edge itself. A dedicated extension works the same way across every browser you use — Chrome on your laptop, Firefox on desktop Linux, Safari on your phone — all pulling from the same encrypted vault instead of three separate silos.
Running two password managers side by side gets noisy fast — you'll get duplicate save prompts every time you log into something. Head into Edge's settings under Profiles → Passwords and turn off "Offer to save passwords" so only your extension prompts you going forward.
Check edge://extensions and confirm the extension has "Allow on all sites" enabled rather than being restricted to specific pages. If it's freshly installed, a full browser restart usually clears up any detection issues on the first few sites you visit.
