Design prompts for sign up pages

A sign up page has one job: get the right person into the product with as little friction as possible, while giving them just enough reason to bother. The ones that convert ask for two or three fields, not ten, lead with social sign in so most people never touch the form, keep one clear primary action, and pair the form with a panel that says what you actually get. The prompts below are the most-copied sign up, login and auth designs in the Superdesign library, from playful split layouts to social-first mobile screens and editorial brand panels. Open any one to see the exact prompt behind it, then tweak the copy and generate your own editable version in seconds.

How to prompt a sign up page that looks designed, not generated

An AI design agent has a strong default for a sign up page, and most of those defaults add friction: a long stack of fields, a confirm-password row, no social sign in, a bare card on a dark purple gradient, and a vague "Sign Up" button. A good prompt is really a list of constraints that override those defaults. Here is each default you need to override, the words that do it, and a template that bakes them all in.

Design a [light or dark] sign up page for [product], a [what it is] for [who it is for].
Fields: ask for only [email and password], no confirm-password field. Note that anything else (name, company, role) is collected after signup, not here.
Social sign in first: [Google, GitHub, Apple] buttons above an "or with email" divider, so most people never touch the form.
One primary action: a single solid [Create account] button. Add a show-password toggle, and a quiet "Already have an account? Log in" link so signup and login never blur.
Value panel: a split layout with the form on one side and a panel that names the one outcome they get, one short testimonial with a name, and a real product mock on the other. Not a bare card on a blank page.
Helpful states: an inline password-strength meter that warns but does not block, a "Forgot password?" link by the field, and specific errors like "That email is already registered. Log in instead?". Include the loading and success states.
Style: a neutral base with one [accent] color reserved for the primary button. Headline typeface [name], body [name], not the default Inter and no purple gradient.
Trust line: a short note under the button, for example "No credit card needed" or a privacy link.

Field count

Default: It asks for everything up front, a stack of name, company, role, phone, password and a confirm-password row, so most people quietly leave.

Constrain it: Cap it at two or three fields, usually email and password, and say the rest is collected after signup with progressive profiling.

Social sign in first

Default: It builds an email-and-password form only, so every visitor has to type even though most would rather tap a provider they already trust.

Constrain it: Name the providers you support (Google, GitHub, Apple) as buttons above an "or with email" divider, so the form is the fallback, not the default.

One clear action

Default: It drops a confirm-password field and two equal-weight buttons, so attention splits and a typo in the second password blocks the signup.

Constrain it: Remove the confirm field and add a show-password toggle, keep one solid primary button, and demote "Log in" to a quiet link.

Give a reason to sign up

Default: It centers a bare form card on a blank or dark gradient canvas, with nothing to tell a stranger why the account is worth creating.

Constrain it: Use a split layout: the form on one side, a value panel on the other naming the one outcome, a short named testimonial, and a real product mock.

Helpful states and recovery

Default: It builds only the happy path: bare fields, a hidden or missing "Forgot password?" link, and a vague "Sign up failed" if anything goes wrong.

Constrain it: Ask for an inline password-strength meter that warns not blocks, a "Forgot password?" link by the field, and specific errors that name the fix and next step.

Color and type

Default: Left alone it defaults to Inter, a dark theme with a purple gradient, and rainbow accents used as decoration.

Constrain it: Name a headline and body typeface and one accent color on a neutral base, and reserve that color for the primary button.

Frequently asked questions

What makes a good sign up page?

Low friction and a clear reason to bother. Ask for two or three fields at most, lead with social sign in so most people never touch the form, keep one obvious primary action, and pair the form with a panel that names the one outcome they get. The best signup screens are short, clear, and confidence-building.

How many fields should a sign up form have?

As few as you can get away with, usually two or three. Forms with three fields convert the best, and asking only for email and a password (no confirm-password row) removes the biggest drop-off. Collect everything else, like company or role, after the account exists, with progressive profiling.

Why does my AI-generated sign up page look generic?

Because a vague prompt gets the model defaults: a long stack of fields with a confirm-password row, no social sign in, a bare card on a dark purple gradient, and the Inter typeface. Cap the fields, put social sign in first, add a value panel, name one accent color and a non-default typeface, and it stops reaching for the average.

Should login and sign up be on the same page?

Keep them as distinct screens with clear labels so a user never has to ask which one they are on. If you do combine them, lead with one and offer a clear link to the other, like "Already have an account? Log in", rather than two equal-weight tabs that blur together.

How do you write a prompt to generate a sign up page UI?

Describe the brief, not the vibe: the product and who it is for, the two or three fields you actually need, the social providers first, one primary action with a show-password toggle, a value panel beside the form, the password-strength and error states, one accent color, and a named typeface. The template above walks through each part, and you can open any example here to see a full prompt that works.

Can I use my own brand colors and copy?

Yes. Generate the layout first, then describe your accent color, typeface, headline and the providers you support in plain language and branch a variant. Every design comes back as real, editable code, so wiring in your auth and brand happens in your own repo, not a rebuild from a picture. Stuck on something? Ping us and we will sort it out together.
