What are mobile login screens?

Mobile login screens let users sign in or create an account on a phone with as little typing as possible: social sign-in, one-time codes, passwordless links and clear error messages.

When to use them

Use them as the entry point of a mobile app or web app, and for verification steps such as entering an SMS code or resetting a password.

Best practices

  • Use autocomplete values like email, current-password and one-time-code.
  • Offer a show password toggle and keep error messages next to the field.
  • Make the primary button full width and easy to reach.
  • Never block paste in password or code fields.

Framework versions

Each screen is available in one of Bootstrap 6, Bootstrap 5, Tailwind CSS or pure CSS. The live preview opens at phone width; switch to tablet or desktop to see how the screen stays centred on larger displays. Copy the HTML, CSS and JavaScript or download the complete page, replace the sample data and connect it to your own API.
