My feature entails adding Apple Passwords support like Safari. It will enhance existing workflows for people using iCloud Keychain (now Apple Passwords).
When a user goes to a login form a popup appears that allows them to autofill the username/password. Currently the only way to autofill passwords with Apple Passwords is to open the context menu > Autofill > Passwords > Search for the relevant site > Manually copy/paste the username & password (you have to redo the steps from the context menu for the username & password individually).
