Single sign-on UI

This design showcases a single sign-on interface with a minimal and modern aesthetic. The layout is clean and focused, providing users with three prominent sign-in options: Apple, Google, and Facebook. A clear call to action for new users to sign up is provided above the sign-in buttons. The interface uses subtle branding with recognizable logos to make the sign-in process straightforward for users. An acknowledgement clause about the terms of service and privacy policy is placed unobtrusively at the bottom.
