Better yet, using the Shortcuts app for iOS, create a shortcut that opens a URL with `prefs:root=PASSWORDS` in Safari.
For macOS, you can make the same shortcut open `/Library/Apple/System/Library/CoreServices/SafariSupport.bundle/Contents/PreferencePanes/Passwords.prefPane`.
A single shortcut can be used to accomplish this, using the OS check and an `if` condition.
Then add the shortcut to the home screen as an icon and it’ll also show up in Spotlight search.
