The only way to copy the keychain phrase is by first clicking on it to show it, that may not be entirely secure if the computer is, for some reason, being watched by someone else or during a recording or a livestream.
Describe the solution you’d like
There should be a button that copies the content of the keychain phrase text box to the clipboard without actually displaying it to the user.
Describe alternatives you’ve considered
Quickly displaying and re-hiding the text, however if, for some reason, the screen is being recorded (either with or without the end user’s consent), the frame could easily be grabbed. Another alternative may be to copy the keychain phrase to a password manager when the user is sure that it would be safe to do so, however that adds another point of failure and doesn’t address the problem that malware could potentially be grabbing screen frames.
That’s the approached followed by most password managers; there are separate “show text” and “copy password to clipboard” buttons to avoid showing the password when it’s not necessary.
