computer is mac, system is high sierra 10.13.4

then my computer update system restarts, and now ssh-t prompts

searched the Internet and found that other people had the same "Enter passphrase for key" prompt,
but the situation was different from mine. I didn"t understand it. I want to know what the problem is. How to configure multiple git accounts with ssh correctly?
