I cannot auto fill nor paste a password into the Mac client like I can the Windows client.
I use a password manager, but the app does not support it (you could support 1Password) so I have no way but to type in a very long password.
This really adds friction to purchases.
Please consider adding support for Password Managers, or just allow pasting. The fear around passwords on the clipboard is overblown, and 1password clears out copied passwords in a short time anyway.
