If you actually use random passwords, this isn't possible. You have to pull up your password in plaintext so you can view it in its entirety and manually count to the correct character, This partial password stuff is just utter garbage. It's lower security than a typical password, way lower security than multi-factor auth, blocks use of password managers, and is generally inconvenient for no good reason.
