# Login Pages and Forms for React and Tailwind

> Login is the door to your product, and everyone walks through it. A good screen is calm and quick, with clear errors and a sensible order of options. Try each one with a password manager and from the keyboard, because that is how people really use it. Install one, then connect it to the authentication you already have. Keep the first screen simple and quiet.

- [Auth Form](https://layro.dev/@educlopez/auth-form.md): A presentation-only sign-in / sign-up form that reveals fields progressively and stays fully accessible. (`npx layro-cli add @educlopez/auth-form`)

## About

Login and sign up components cover the way into an app: sign in forms with email and password, magic links, social buttons such as GitHub and Google, sign up forms, password reset screens, two factor prompts and split layouts with a product image beside the form.

Offer the methods your users actually have, label every field, and let password managers do their job with the right autocomplete values. Show errors without saying which part was wrong, and keep the page fast and plain, since nobody wants to wait to sign in.

## Frequently asked questions

### How do I build a login page in React?

A form with labelled email and password fields and a submit button, posting to your auth provider or server. Libraries such as Better Auth, Auth.js or Clerk handle sessions.

### Which autocomplete values should login fields use?

Use username or email on the identifier, current-password on the password when signing in and new-password when signing up, so password managers fill and save correctly.

### Should I offer social login?

Yes, if your users have those accounts, since it's quicker and avoids another password. Keep an email option for people who don't want to link a social account.

### What is a magic link login?

Signing in by clicking a one time link sent to your email instead of typing a password. Links should expire quickly and work only once.

### How should login errors be worded?

Say the email or password is incorrect without saying which, so attackers can't learn which accounts exist, and keep what was typed in the email field.

### Should sign up and sign in be one page?

They can share a page with a switch between them, or start with email and branch based on whether an account exists. Make the difference obvious.

### How do I add a show password toggle?

Add a button inside the field that switches the input type between password and text, with an accessible label that changes to match.
