I’m using Brave and Firefox on a Mac, both want to open the “System Settings” app - this works, OSX will open the Settings and propose to add the otp directory to an entry in your password manager. For 1password, I copied the entire link (including the otpauth://) and pasted it in the additional field of “one time password” - I verified both with logoutlogin and no problems. It does not work with authy, but for that you could follow @m-p-3@kbin.social 's addon link and scan the QR with the phone app.
