Here’s what the team came up with! These aren’t “officially endorsed” solutions and I haven’t tested them myself, but hopefully you’ll find some use of them:
Chrome, Brave, Vivaldi
chrome-extension://nngceckbapebfimnlniiiahkandclblb/popup/index.html?uilocation=popout#/lock
Opera:
chrome-extension://ccnckbpmaceehanjmeomladnmlffdjgn/popup/index.html?uilocation=popout#/lock
Edge
extension://jbkfoedolllekgbhcbcoahefnbanhhlh/popup/index.html?uilocation=popout#/lock
Firefox, Tor browser:
moz-extension://a01abe27-c9d4-48ef-aed2-a0acca72a6fa/popup/index.html?uilocation=popout#/lock
You can change that end string there to get to different pages too:
Login screen:
/popup/index.html?uilocation=popout#/home
Lock screen
/popup/index.html?uilocation=popout#/lock
Either should work/re-route depending on your vault state.
(the above are all set to be the lock page)
