Ryan Christoffel has a great tip regarding generated-but-not-yet-saved passwords in Apple’s Passwords app:
Now, when new passwords have been generated in iOS, but aren’t fully saved inside the Passwords app, a new menu option appears.
Available behind the three-dot icon in Passwords’ top-right corner, you’ll see a ‘Generated Passwords’ option.
I’m in the midst of transitioning from 1Password to Apple Passwords (so far, so good!), so I’m happy to have run across this.
